An early member of the FASF, Charlie Overstreet, took his final flight two weeks ago from his home in El Paso, Texas. He was also an active member of the El Paso Daedalian Flight 24 and one of its former Captains. Charlie, over the past ten years, has also been one of our FASF Aviation News Reporters. He was a long-time docent at Santa Teresa’s, New Mexico’s War Eagles Air Museum (WEAM), and was an active member of its Board of Directors. Both the Daedalians, the WEAM, and the FASF will sorely miss Charlie’s positive personality and his incessant “can do” spirit. Here, below, is his Daedalian Flight’s Memorial headline honoring his long service (his wife of 61 years, Mayre Sue, is at the far right with Charlie at a Daedalian gathering):
Charles “Charlie” Overstreet passed away on February 3, 2022. He was born in 1937 to Charlesand Zelma Overstreet.Charlie’sdad was a Coast Guard officer and his earliest memories were of being at Coast Guard Air Stations all around the country, watching airplanes with his dad and younger brother Lane Overstreet. This inspired a lifelong passion for aviation and patriotism.
Upon graduation from the University of Miami, Where he was a member of the AFROTC unit, Charlie was commissioned a 2nd Lieutenant in the USAF.
He entered pilot training at Big Spring, Texas where he met his future wife Mayre Sue. They married in the summer of 1961 when he finished B-47 Stratojet bomber training and was assigned to Forbes AFB, Kansas. While in Kansas, Charlie and Mayre Sue had two sons. The oldest Charles Overstreet was born in the middle of the Cuban Missile Crises, Charlie had to take a couple of hours off a nuclear alert to be at the hospital. James Overstreet was born just before his dad left for B-52 Stratofortess bomber combat crew transition training at Castle AFB, California. In 1969 Charlieand his B-52 combat crew joined the conflict in Vietnam, where he flew 55 combat missions during Operation ArcLight. Upon returning from South East Asia, Charlie left active duty with the USAF.
In 1971 the US Customs Service Sky Marshal program hired Charlie and in 1972 he was promoted to a Special Agent/Pilot position in San Antonio, TX. He transferred to DEA in 1973 as one of the initial stand-up cadre. Within a couple of years, he helped stand up the air branch supporting sensitive counter narcotics’ operation, sometimes doing things with airplanes that are generally frowned upon today.
In 1985 he transferred to El Paso, retiring from DEA in 1994. Refusing to slow down, for 17 years Charlietaught as a substitute teacher at Coronado High School. After retiring from teaching Charlie became a volunteer at the War Eagles Air Museum, he just loved being around airplanes. Charlie enjoyed working with his colleagues on the War Eagle museum staff and as a docent for visiting students.
One of his most recent and passionate endeavors was honoring our Texas and New Mexico veterans through the organization and development of the Santa Teresa Veterans Memorial Park in Santa Teresa, New Mexico. He enjoyed hunting, skeet/trap shooting, cigars, and traveling around the world with his family and friends. Charlie was a member of Safari Club International, The Order of the Daedalians, and the FASF.

The world’s first operational jet, was the German invented WWI Fighter-Bomber, the Messerschmitt ME-262, which was first produced in 1944, but abruptly terminated when Nazi Germany surrendered to the Allied Forces on May 7, 1945. But, as this series explains, the Germans were actively working on this revolutionary aircraft way back in the 1930s. The below three videos produced in Great Britain and Germany by Bismarck, who hosts the Military Aviation Channel.
The Messerschmitt Me 262, nicknamed Schwalbe (German: “Swallow“) in fighter versions, or Sturmvogel (German: “Storm Bird“) in the fighter-bomber configurations, was the world’s first operational jet-powered fighter aircraft. Design work started before World War II began, but problems with engines, metallurgy and top-level interference kept the aircraft from operational status with the Luftwaffe until mid-1944. The Me 262 was faster and more heavily armed than any Allied fighter, including the British jet-powered Gloster Meteor.One of the most advanced aviation designs in operational use during World War II,the Me 262’s roles included light bomber, reconnaissance and experimentalnight fighter versions.
In the relatively short period of its operation the ME-262 pilots claimed a total of 542 Allied aircraft shot down,although higher claims are sometimes made.The Allies countered its effectiveness in the air by attacking the aircraft on the ground and during takeoff and landing.
Strategic materials shortages and design compromises on the Junkers Jumo 004 axial-flow turbojet engines led to reliability problems. Attacks by Allied forces on fuel supplies during the deteriorating late-war situation also reduced the effectiveness of the aircraft as a fighting force. Armament production within Germany was focused on more easily manufactured aircraft.In the end, the Me 262 had a negligible impact on the course of the war as a result of its late introduction and the consequently small numbers put in operational service.
Captured Me 262s were studied and flight tested by the major powers, and ultimately influenced the designs of post-war aircraft such as the North American F-86 Sabre, MiG-15 and Boeing B-47 Stratojet.Several aircraft survive on static display in museums, and there are several privately built flying reproductions that use modern General Electric J85 engines.
In addition to our thanks for Bismarck’squality videos shown below, we also need to recognized the fine research and writing skills of the people at WikiMili, who are the principle contributors to this background information of this famous German jet.

And, here follows Bismarck’s video about the ME-262’s basic history. 23:32
And, here below is part II of the “inside the cockpit of the ME0262” at 11:22
Several years before World War II, the Germans foresaw the great potential for aircraft that used the jet engine constructed by Hans Joachim Pabst von Ohain in 1936. After the successful test flights of the world’s first jet aircraft—the Helsinki He 178—within a week of the Invasion of Poland to start the war, they adopted the jet engine for an advanced fighter aircraft. As a result, the Me 262 was already under development as Projekt 1065 (P.1065) before the start of World War II.
The project originated with a request by the Reichsluftfahrtministerium (RLM, Ministry of Aviation) for a jet aircraft capable of one hour’s endurance and a speed of at least 850 km/h (530 mph; 460 kn). Dr. Waldemar Voigtheaded the design team, with Messerschmitt’s chief of development, Robert Lusser, overseeing.
Plans were first drawn up in April 1939, and the original design was very different from the aircraft that eventually entered service, with wing root-mounted engines,rather than podded ones, when submitted in June 1939. The progression of the original design was delayed greatly by technical issues involving the new jet engine. Because the engines were slow to arrive, Messerschmitt moved the engines from the wing roots to under wing pods, allowing them to be changed more readily if needed; this would turn out to be important, both for availability and maintenance.Since the BMW 003 jets proved heavier than anticipated, the wing was swept slightly, by 18.5°, to accommodate a change in the center of gravity.
Funding for the jet engine program was also initially lacking as many high-ranking officials thought the war could easily be won with conventional aircraft. Among those were Hermann Göring,head of the Luftwaffe, who cut the engine development program to just 35 engineers in February 1940 (the month before the first wooden mock-up was completed);Willy Messerschmitt, who desired to maintain mass production of the piston-powered, 1935-origin BF-109 and the projected ME-209; and Major General Adolf Galland, who had initially supported Messerschmitt through the early development years, flying the Me 262 himself on 22 April 1943. By that time, problems with engine development had slowed production of the aircraft considerably.
One particularly acute problem arose with the lack of an alloy with a melting point high enough to endure the high temperatures involved, a problem that by the end of the war had not been adequately resolved.
The aircraft made its first successful flight entirely on jet power on 18 July 1942, powered by a pair of Jumo 004 engines, after a November 1941 flight (with BMW 003s) ended in a double flameout.
The project aerodynamicist on the design of the Me 262 was Ludwig Bölkow. He initially designed the wing using NACAairfoilsmodified with an elliptical nose section.Later in the design process, these were changed to AVL derivatives of NACA airfoils, the NACA 00011-0.825-35 being used at the root and the NACA 00009-1.1-40 at the tip. The elliptical nose derivatives of the NACA airfoils were used on the horizontal and vertical tail surfaces.
Wings were of single-spar cantilever construction, with stressed skins, varying from 3 mm (0.12 in) skin thickness at the root to 1 mm (0.039 in) at the tip. To expedite construction, save weight and use less strategic materials, late in the war, wing interiors were not painted.The wings were fastened to the fuselage at four points, using a pair of 20 mm (0.79 in) and forty-two 8 mm (0.31 in) bolts.
In mid-1943, Adolf Hitlerenvisioned the Me 262 as a ground-attack/bomber plane rather than a defensive interceptor. The configuration of a high-speed, light payload Schnellbomber (“fast bomber”) was intended to penetrate enemy airspace during the expected Allied invasion of France. His edict resulted in the development of (and concentration on) the Sturmvogelvariant.
It is debatable to what extent Hitler’s interference extended the delay in bringing the Schwalbe into operation; it appears engine vibration issues were at least as costly, if not more so.
Albert Speer, then Minister of Armaments and War Production, in his memoirs claimed Hitleroriginally had blocked mass production of the Me 262, before agreeing in early 1944. Hitlerrejected arguments the aircraft would be more effective as a fighter against the Allied bombers destroying large parts of Germany, and wanted it as a bomber for revenge attacks. According to Speer,Hitler felt its superior speed compared to other fighters of the era meant it could not be attacked, and so preferred it for high altitude straight flying.
The Me 262 is often referred to as a “swept wing” design as the production aircraft had a small, but significant leading edge sweep of 18.5° which likely provided an advantage by increasing the critical Mach number. Sweep, uncommon at the time, was added after the initial design of the aircraft. The engines proved heavier than originally expected, and the sweep was added primarily to position the center of lift properly relative to the center of mass. (The original 35° sweep, proposed by Adolf Busemann, was not adopted.)On 1 March 1940, instead of moving the wing backward on its mount, the outer wing was re-positioned slightly aft; the trailing edge of the midsection of the wing remained unswept.Based upon data from the AVA Göttingen and wind tunnel results, the inboard section’s leading edge (between the nacelle and wing root) was later swept to the same angle as the outer panels, from the “V6” sixth prototype onward throughout volume production.
On 19 April 1944, Erprobungskommando262 was formed at Lechfeld just south of Augsburg, as a test unit (Jäger Erprobungskommando Thierfelder, commanded by HauptmannWerner Thierfelder)to introduce the 262 into service and train a corps of pilots to fly it.
On 26 July 1944, Leutnant Alfred Schreiber with the 262 A-1a W.Nr. 130 017 damaged a Mosquito reconnaissance aircraft of No. 540 Squadron RAF PR Squadron, which was allegedly lost in a crash upon landing at an air base in Italy.Other sources state the aircraft was damaged during evasive maneuvers, and escaped.
Major Walter Nowotny was assigned as commander after the death of Thierfelder in July 1944, and the unit re-designatedKommando Nowotny. Essentially a trials and development unit, it mounted the world’s first jet fighter operations. Trials continued slowly, with initial operational missions against the Allies in August 1944, and the unit made claims for 19 Allied aircraft in exchange of six Me 262s lost.
Despite orders to stay grounded, Nowotny chose to fly a mission against an enemy bomber formation flying some 9,100 m (30,000 ft) above, on 8 November 1944. He claimed two P-51Ds destroyed before suffering engine failure at high altitude.Then, while diving and trying to restart his engines, he was attacked by other Mustangs, forced to bail out, and died. The Kommando was then withdrawn for further flight training and a revision of combat tactics to optimize the 262’s strengths.
On 26 November 1944, a Me 262A-2a Sturmvogel of III.Gruppe/KG 51 ‘Edelweiß’ based at Rheine-Hopsten Air Base near Osnabrück was the first confirmed ground-to-air kill of a jet combat aircraft. The 262 was shot down by a Bofors gun of B.11 Detachment of 2875 Squadron RAF Regiment at the RAF forward airfield of Helmond, near Eindhoven.
Others were lost to ground fire on 17 and 18 December when the same airfield was attacked at intervals by a total of 18 Me 262s and the guns of 2873 and 2875 Squadrons RAF Regiment damaged several, causing at least two to crash within a few miles of the airfield. In February 1945, a B.6 gun detachment of 2809 Squadron RAF Regiment shot down another Me 262 over the airfield of Volkel. The final appearance of 262s over Volkel was in 1945 when yet another fell to 2809’s guns.
By January 1945, Jagdgeschwader 7 (JG 7) had been formed as a pure jet fighter wing, partly based at Parchim, although it was several weeks before it was operational. In the meantime, a bomber unit—I Gruppe, Kampfgeschwader 54 (KG(J) 54)—re-designated as such on 1 October 1944through being re-equipped with, and trained to use the Me 262A-2a fighter-bomber for use in a ground-attack role. However, the unit lost 12 jets in action in two weeks for minimal returns.Jagdverband 44 (JV 44) was another Me 262 fighter unit, of squadron (Staffel) size given the low numbers of available personnel, formed in February 1945 by Lieutenant General Adolf Galland,who had recently been dismissed as Inspector of Fighters. Gallandwas able to draw into the unit many of the most experienced and decorated Luftwaffe fighter pilots from other units grounded by lack of fuel.
During March, Me 262 fighter units were able, for the first time, to mount large-scale attacks on Allied bomber formations. On 18 March 1945, thirty-seven Me 262s of JG 7 intercepted a force of 1,221 bombers and 632 escorting fighters. They shot down 12 bombers and one fighter for the loss of three Me 262s. Although a 4:1 ratio was exactly what the Luftwaffe would have needed to make an impact on the war, the absolute scale of their success was minor, as it represented only 1% of the attacking force.
In the last days of the war, Me 262s from JG 7 and other units were committed in ground assault missions, in an attempt to support German troops fighting Red Army forces. Just south of Berlin, halfway between Spremberg and the German capital, Wehrmacht’s 9th Army (with elements from the 12 Army and 4th Panzer Army) was assaulting the Red Army’s 1st Ukrainian Front.
To support this attack, on 24 April, JG 7 dispatched thirty-one Me 262s on a strafing mission in the Cottbus-Bautzen area. Luftwaffe pilots claimed six lorries and seven Soviet aircraft, but three German jets were lost. On the evening of 27 April, thirty-six Me 262s from JG 7, III.KG(J)6 and KJ(J)54 were sent against Soviet forces that were attacking German troops in the forests north-east of Baruth. They succeeded in strafing 65 Soviet lorries, after which the Me 262s intercepted low flying L-2 Sturmoviks searching for German tanks. The jet pilots claimed six Sturmoviks for the loss of three Messerschmitts. During operations between 28 April and 1 May Soviet fighters and ground fire downed at least ten more Me 262s from JG 7.However, JG 7 managed to keep its jets operational until the end of the war. And on the 8th of May, at around 4:00 p.m. Oblt. Fritz Stehle of 2./JG 7, while flying a Me 262 on the Erzgebirge, attacked a formation of Soviet aircraft. He claimed a Yakovlev Yak-9, but the plane shot down was probably a P-39 Airacobra. Soviet records show that they lost two Airacobras, one of them probably downed by Stehle,who would thus have scored the last Luftwaffe air victory of the war.
Several two-seat trainer variants of the Me 262, the Me 262 B-1a, had been adapted through the Umrüst-Bausatz 1 factory refit package as night fighters, complete with on-board FuG 218 Neptun high-VHF band radar, using Hirschgeweih (“stag’s antlers”) antennae with a set of dipole elements shorter than the Lichtenstein SN-2 had used, as the B-1a/U1 version. Serving with 10. StaffelNachtjagdgeschwader 11, near Berlin, these few aircraft (alongside several single-seat examples) accounted for most of the 13 Mosquitoes lost over Berlin in the first three months of 1945.Intercepts were generally or entirely made using Wilde Saumethods, rather than AI radar-controlled interception. As the two-seat trainer was largely unavailable, many pilots made their first jet flight in a single-seater without an instructor.
Despite its deficiencies, the Me 262 clearly marked the beginning of the end of piston-engined aircraft as effective fighting machines. Once airborne, it could accelerate to speeds over 850 km/h (530 mph), about 150 km/h (93 mph) faster than any Allied fighter operational in the European Theater of Operations.
The Me 262’s top ace was probably HauptmannFranz Schallwith 17 kills, including six four-engine bombers and ten P-51 Mustang fighters, although fighter ace OberleutnantKurt Welter claimed 25 Mosquitos and two four-engine bombers shot down by night and two further Mosquitos by day. Most of Welter’sclaimed night kills were achieved by eye, even though Welter had tested a prototype Me 262 fitted with FuG 218 Neptun radar. Another candidate for top ace on the aircraft was OberstleutnantHeinrich Bär, who is credited with 16 enemy aircraftwhile flying Me262’s out of his total of 240 aircraft shot down.
The Me 262 was so fast that German pilots needed new tactics to attack Allied bombers. In the head-on attack, the combined closing speed of about 320 m/s (720 mph) was too high for accurate shooting, with ordnance that could only fire about 44 shells a second (650 rounds/min from each cannon) in total from the quartet of them. Even from astern, the closing speed was too great to use the short-ranged quartet of MK 108 cannon to maximum effect.
Therefore, a roller-coaster attack was devised. The 262s approached from astern and about 1,800 m higher (5,900 ft) than the bombers. From about five km behind (3.1 mi), they went into a shallow dive that took them through the escort fighters with little risk of interception. When they were about 1.5 km astern (0.93 mi) and 450 m (1,480 ft) below the bombers, they pulled up sharply to reduce speed. On levelling off, they were one km astern (1,100 yd) and overtaking the bombers at about 150 km/h (93 mph), well placed to attack them.
Since the 30mm MK 108 cannon‘s short barrels and low muzzle velocity (only 540 m/s (1,900 km/h; 1,200 mph)) rendered it inaccurate beyond 600 m (660 yd; 2,000 ft), coupled with the jet’s velocity, which required breaking off at 200 m (220 yd; 660 ft) to avoid colliding with the target, Me 262 pilots normally commenced firing at 500 m (550 yd; 1,600 ft).Gunners of Allied bomber aircraft found their electrically powered gun turrets had problems tracking the jets.Target acquisition was difficult because the jets closed into firing range quickly and remained in firing position only briefly, using their standard attack profile, which proved more effective.
A prominent Royal Navy test pilot, Captain Eric Brown, chief naval test pilot and commanding officer of the Captured Enemy Aircraft Flight Royal Aircraft Establishment, who tested the Me 262 noted:
“This was a Blitzkrieg aircraft. You whack in at your bomber. It was never meant to be a dogfighter, it was meant to be a destroyer of bombers . . . The great problem with it was it did not have dive brakes. For example, if you want to fight and destroy a B-17, you come in on a dive. The 30mm cannon were not so accurate beyond 600 metres [660 yd; 2,000 ft]. So you normally came in at 600 yards [550 m; 1,800 ft] and would open fire on your B-17. And your closing speed was still high and since you had to break away at 200 metres [220 yd; 660 ft] to avoid a collision, you only had two seconds firing time. Now, in two seconds, you can’t sight. You can fire randomly and hope for the best. If you want to sight and fire, you need to double that time to four seconds. And with dive brakes, you could have done that.”
Eventually, German pilots developed new combat tactics to counter Allied bombers’ defenses.
Me 262s, equipped with up to 24 unguided folding-fin R4M rockets—12 in each of two under wing racks, outboard of the engine nacelle—approached from the side of a bomber formation, where their silhouettes were widest, and while still out of range of the bombers’ machine guns, fired a salvo of rockets with strongly brisant Hexogen-filled warheads, exactly the same explosive in the shells fired by the Me 262A’s quartet of MK 108 cannon. One or two of these rockets could down even the famously rugged Boeing B-17 Flying Fortress,from the “metal-shattering” brisant effect of the fast-flying rocket’s 520 g (18 oz) explosive warhead. The much more massive BR-21 large-caliber rockets, used from their tubular launchers in under nose locations for an Me 262A’s use (one either side of the nose wheel well) were only as fast as the MK 108’s shells.
Though this broadside-attack tactic was effective, it came too late to have a real effect on the war, and only small numbers of Me 262s were equipped with the rocket packs.Most of those so equipped were Me 262A-1a models, members of Jagdgeschwader 7.This method of attacking bombers became the standard, and mass deployment of Ruhrstahl X-4 guided missiles was cancelled. Some nicknamed this tactic the Luftwaffe’s Wolf Pack, as the fighters often made runs in groups of two or three, fired their rockets, then returned to base. On 1 September 1944, USAAF General Carl “Tooey” Spaatz expressed the fear that if greater numbers of German jets appeared, they could inflict losses heavy enough to force cancellation of the Allied bombing offensive by daylight.
The Me 262 was difficult to counter because its high speed and rate of climb made it hard to intercept. However, as with other turbojet engines at the time, the Me 262’s engines did not provide sufficient thrust at low air speeds and throttle response was slow, meaning in certain circumstances such as takeoff and landing, the aircraft became a vulnerable target.
Another disadvantage that pioneering jet aircraft of the World War II era shared, was the high risk of compressor stall and if throttle movements were too rapid, the engine(s) could suffer a flameout. The coarse opening of the throttle would cause fuel surging and lead to excessive jet pipe temperatures. Pilots were instructed to operate the throttle gently and avoid quick changes. German engineers introduced an automatic throttle regulator later in the war but it only partly alleviated the problem.
The plane had, by contemporary standards, a high wing loading (294.0kg/m2, 60.2lbs/ft2) that required higher takeoff and landing speeds. Due to poor throttle response, the engines’ tendency for airflow disruption that could cause the compressor to stall was ubiquitous. The high speed of the Me 262 also presented problems when engaging enemy aircraft, the high-speed convergence allowing Me 262 pilots little time to line up their targets or acquire the appropriate amount of deflection. This problem faces any aircraft that approaches another from behind at much higher speed, as the slower aircraft in front can always pull a tighter turn, forcing the faster aircraft to overshoot.
“I passed one that looked as if it was hanging motionless in the air (I am too fast!). The one above me went into a steep right-hand turn, his pale blue underside standing out against the purple sky. Another banked right in front of the Me’s nose. Violent jolt as I flew through his airscrew eddies. Maybe a wing’s length away. That one in the gentle left-hand curve! Swing her round. I was coming from underneath, eye glued to the sight (pull her tighter!). A throbbing in the wings as my cannon pounded briefly. Missed him. Way behind his tail. It was exasperating. I would never be able to shoot one down like this. They were like a sack of fleas. A prick of doubt: is this really such a good fighter? Could one in fact, successfully attack a group of erratically banking fighters with the Me 262?”
Luftwaffe pilots eventually learned how to handle the Me 262’s higher speed and the Me 262 soon proved a formidable air superiority fighter, with pilots such as Franz Schall managing to shoot down seventeen enemy fighters in the Me 262, ten of them American P-51 Mustangs.
Other notable Me 262 aces included Georg-Peter Eder, with twelve enemy fighters to his credit (including nine P-51s), Erich Rudorfferalso with twelve enemy fighters to his credit, Walther Dahl with eleven (including three Lavochkin La-7s and six P-51s) and Heinz-Helmut Baudach with six (including one Spitfire and two P-51s) amongst many others.
Pilots soon learned that the Me 262 was quite maneuverable despite its high wing loading and lack of low-speed thrust, especially if attention was drawn to its effective maneuvering speeds. The controls were light and effective right up to the maximum permissible speed and perfectly harmonized. The inclusion of full span automatic leading-edge slats,something of a “tradition” on Messerschmitt fighters dating back to the original BF-109’s outer wing slots of a similar type, helped increase the overall lift produced by the wing by as much as 35% in tight turns or at low speeds, greatly improving the aircraft’s turn performance as well as its landing and takeoff characteristics.As many pilots soon found out, the Me 262’s clean design also meant that it, like all jets, held its speed in tight turns much better than conventional propeller-driven fighters, which was a great potential advantage in a dogfight as it meant better energy retention in maneuvers.
Too fast to catch for the escorting Allied fighters, the Me 262s were almost impossible to head off. As a result, Me 262 pilots were relatively safe from the Allied fighters, as long as they did not allow themselves to get drawn into low-speed turning contests and saved their maneuvering for higher speeds. Combating the Allied fighters could be effectively done the same way as the U.S. fighters fought the more nimble, but slower, Japanese fighters in the Pacific.
Allied pilots soon found that the only reliable way to destroy the jets, as with the even faster Me-163B Komet rocket fighters, was to attack them on the ground or during takeoff or landing.
Luftwaffe airfields identified as jet bases were frequently bombed by medium bombers, and Allied fighters patrolled over the fields to attack jets trying to land. The Luftwaffe countered by installing extensive flak alleys of anti-aircraft guns along the approach lines to protect the Me 262s from the ground—and by providing top cover during the jets’ takeoff and landing with the most advanced Luftwaffe single-engined fighters, the Focke-Wulf Fw 190D and (just becoming available in 1945) Focke-Wulf Ta 152H.Nevertheless, in March–April 1945, Allied fighter patrol patterns over Me 262 airfields resulted in numerous jet losses.
As the Me 262A’s pioneering Junkers Jumo 004 axial-flow jet engines needed careful nursing by their pilots.
These radically new jet aircraft were particularly vulnerable during takeoff and landing.
Lt. Chuck Yeager of the 357th Fighter Group was one of the first American pilots to shoot down an Me 262, which he caught during its landing approach.On 7 October 1944, Lt. Urban Drew of the 365th Fighter Group shot down two Me 262s that were taking off, while on the same day Lt. Col. Hubert Zemke,who had transferred to the Mustang equipped 479th Fighter Group, shot down what he thought was a BF-109, only to have his gun camera film reveal that it may have been an Me 262.On 25 February 1945, Mustangs of the 55th Fighter Group surprised an entire Staffel of Me 262As at takeoff and destroyed six jets.
The British Hawker Tempest scored several kills against the new German jets, including the Messerschmitt Me 262. Hubert Lange, a Me 262 pilot, said: “the Messerschmitt Me 262’s most dangerous opponent was the British Hawker Tempest—extremely fast at low altitudes, highly maneuverable and heavily armed.”Some were destroyed with a tactic known to the Tempest 135 Wing as the “Rat Scramble”:Tempests on immediate alert took off when an Me 262 was reported airborne. They did not intercept the jet, but instead flew towards the Me 262 and Ar 234 base at Hopsten air base.The aim was to attack jets on their landing approach, when they were at their most vulnerable, travelling slowly, with flaps down and incapable of rapid acceleration.The German response was the construction of a “flak lane” of over 150 emplacements of the 20mm Flakvierling quadruple auto cannon batteries at Rheine-Hopsten to protect the approaches.After seven Tempests were lost to flak at Hopsten in a week, the “Rat Scramble” was discontinued.
Adolf Busemann had proposed swept wings as early as 1935; Messerschmitt researched the topic from 1940. In April 1941, Busemann proposed fitting a 35° swept wing (Pfeilflügel II, literally “arrow wing II”) to the Me 262,the same wing-sweep angle later used on both the American F-86 Sabre and Soviet Mikoyan-Gurevich MiG-15 fighter jets. Though this was not implemented, he continued with the projected HG II and HG III (Hochgeschwindigkeit, “high-speed”) derivatives in 1944, designed with a 35° and 45° wing sweep, respectively.
Interest in high-speed flight, which led him to initiate work on swept wings starting in 1940, is evident from the advanced developments Messerschmitthad on his drawing board in 1944.
While the Me 262 V9 Hochgeschwindigkeit I (HG I) flight-tested in 1944 had only small changes compared to combat aircraft, most notably a low-profile canopy—tried as the Rennkabine (literally “racing cabin”) on the ninth Me 262 prototype for a short time—to reduce drag, the HG II and HG III designs were far more radical. The projected HG II combined the low-drag canopy with a 35° wing sweep and a V-tail (butterfly tail). The HG III had a conventional tail, but a 45° wing sweep and turbines embedded in the wing roots.
Messerschmitt also conducted a series of flight tests with the series production Me 262. Dive tests determined that the Me 262 went out of control in a dive at Mach 0.86, and that higher Mach numbers would cause a nose-down trim that the pilot could not counter. The resulting steepening of the dive would lead to even higher speeds and the airframe would disintegrate from excessive negative G loads.
The HG series of Me 262 derivatives was believedcapable of reaching transonic Mach numbers in level flight, with the top speed of the HG III being projected as Mach0.96 at 6,000 m (20,000 ft) altitude. After the war, the Royal Aircraft Establishment, at that time one of the leading institutions in high-speed research, re-tested the Me 262 to help with British attempts at exceeding Mach1. The RAE achieved speeds of up to Mach0.84 and confirmed the results from the Messerschmitt dive-tests. The Soviets ran similar tests.
After Willy Messerschmitt’sdeath in 1978, the former Me 262 pilot Hans Guido Mutke claimed to have exceeded Mach1 on 9 April 1945 in a Me 262 in a “straight-down” 90° dive. This claim relies solely on Mutke’s memory of the incident, which recalls effects other Me 262 pilots observed below the speed of sound at high indicated airspeed, but with no altitude reading required to determine the speed.
The pitot tube used to measure airspeed in aircraft can give falsely elevated readings as the pressure builds up inside the tube at high speeds. The Me 262 wing had only a slight sweep, incorporated for trim (center of gravity) reasons and likely would have suffered structural failure due to divergence at high transonic speeds. One airframe—the aforementioned Me 262 V9, Werknummer 130 004, with Stammkennzeichen of VI+AD,was prepared as the HG I test airframe with the low-profile Rennkabine racing-canopy and may have achieved an unofficial record speed for a turbojet-powered aircraft of 975 km/h (606 mph), altitude unspecified,even with the recorded wartime airspeed record being set on 6 July 1944, by another Messerschmitt design—the Me 163B V18rocket fighter setting a 1,130 km/h (700 mph) record, but landing with a nearly disintegrated rudder surface.
About 1,400 planes were produced, but a maximum of 200 were operational at any one time. According to sources they destroyed from 300 to 450 enemy planes, with the Allies destroying about one hundred Me 262s in the air.While Germany was bombed intensively, production of the Me 262 was dispersed into low-profile production facilities, sometimes little more than clearings in the forests of Germany and occupied countries.
Through the end of February to the end of March 1945, approximately sixty Me 262s were destroyed in attacks on Obertraubling and thirty at Leipheim;the Neuburg jet plant itself was bombed on 19 March 1945.
Large, heavily protected underground factories were constructed – as with the partly-buried Weingut I complex for Jumo 004 jet engine production – to take up production of the Me 262, safe from bomb attacks, but the war ended before they could be completed. Wings were produced in Germany’s oldest motorway tunnel at Engelberg, to the west of Stuttgart. At B8 Bergkristall-Esche II at St. Georgen/Gusen, Austria, slave labourers of concentration camp Gusen II produced fully equipped fuselages for the Me 262 at a monthly rate of 450 units on large assembly lines from early 1945.Gusen II was known as one of the harshest concentration camps; the typical life expectancy was six months.An estimated 35,000 to 50,000 people died on the forced labor details for the Me 262.
After the end of the war, the Me 262 and other advanced German technologies were quickly swept up by the Soviets, British and Americans, as part of the USAAF’s Operation Lusty. Many Me 262s were found in readily repairable condition and were confiscated. The Soviets, British and Americans wished to evaluate the technology, particularly the engines.
During testing, the Me 262 was found to be faster than the British Gloster Meteor jet fighter, and had better visibility to the sides and rear (mostly due to the canopy frames and the discoloration caused by the plastics used in the Meteor’s construction), and was a superior gun platform to the Meteor F.1 which had a tendency to snake at high speed and exhibited “weak” aileron response.The Me 262 had a shorter range than the Meteor and had less reliable engines.
The USAAF compared the P-80 Shooting Star and Me 262, concluding that the Me 262 was superior in acceleration and speed, with similar climb performance. The Me 262 appeared to have a higher critical Mach number than any American fighter.
The Americans also tested a Me 262A-1a/U3 unarmed photo reconnaissance version, which was fitted with a fighter nose and a smooth finish. Between May and August 1946, the aircraft completed eight flights, lasting four hours and forty minutes. Testing was discontinued after four engine changes were required during the course of the tests, culminating in two single-engine landings.These aircraft were extensively studied, aiding development of early US, British and Soviet jet fighters. The F-86, designed by engineer Edgar Schmued, used a slat design based on the Me 262’s.
The Czechoslovak aircraft industry continued to produce single-seat (Avia S-92) and two-seat (Avia CS-92) variants of the Me 262 after World War II. From August 1946, a total of nine S-92s and three two-seater CS-92s were completed and test flown. They were introduced in 1947 and in 1950 were supplied to the 5th Fighter Squadron, becoming the first jet fighters to serve in the Czechoslovak Air Force. These were kept flying until 1951,when they were replaced in service by Soviet jet fighters. Both versions are on display at the Prague Aviation museum in Kbely.
In January 2003, the American Me 262 Project, based in Everett, Washington, completed flight testing to allow the delivery of partially updated spec reproductions of several versions of the Me 262 including at least two B-1c two-seater variants, one A-1c single seater and two “convertibles” that could be switched between the A-1c and B-1c configurations. All are powered by General Electric CJ610 engines and feature additional safety features, such as upgraded brakes and strengthened landing gear. The “c” suffix refers to the new CJ610 power plant and has been informally assigned with the approval of the Messerschmitt Foundation in Germany(the Werknummer of the reproductions picked up where the last wartime produced Me 262 left off – a continuous airframe serial number run with a near 60-year production break).
Flight testing of the first newly manufactured Me 262 A-1c (single-seat) variant (Werknummer 501244) was completed in August 2005. The first of these machines (Werknummer 501241) went to a private owner in the southwestern United States, while the second (Werknummer 501244) was delivered to the Messerschmitt Foundation at Manching, Germany. This aircraft conducted a private test flight in late April 2006, and made its public debut in May at the ILA 2006. The new Me 262 flew during the public flight demonstrations.Me 262 Werknummer 501241 was delivered to the Collings Foundation as White 1 of JG 7; this aircraft offered ride-along flights starting in 2008.The third replica, a non-flyable Me 262 A-1c, was delivered to the Evergreen Aviation & Space Museum in May 2010.
The following 37 minute film is from the archives of the USAF. We dedicate it to those veterans of the Cold War among our members, in particular to one of our Aviation News Scouts, Charlie Overstreet, who accumulated many hours in this Boeing Strategic Bomber, as well as in the successor B-52 Stratofortress, which is still on active duty to this day.
