31 March 1945: Messerschmitt Aktiengesellschaft test pilot and technical inspector Hans Fay (1888–1959) defected to the Allies at Frankfurt/Rhein-Main Airfield, Frankfurt, Germany.

He brought with him a brand-new Messerschmitt Me 262 A-1 twin-engine jet fighter.

Fay had been waiting for an opportunity to bring an Me 262 to the Americans, but feared reprisals against his parents. When he learned that the U.S. Army controlled their town, he felt that it was safe to go ahead with his plan.

On 31 March, Fay was ordered to fly one of twenty-two new fighters from the Me 262 assembly factory at Schwäbisch-Hall to a safer location at Neuburg an der Donau, as they were in danger of being captured by advancing Allied forces. His airplane was unpainted other than low visibility Balkenkreuz markings on the wings and fuselage, and standard Luftwaffe markings on the vertical fin. Fay was the fourth to take off, but instead of heading east-southeast toward Neuburg, he flew north-northwest to Frankfurt, arriving there at 1:45 p.m.

The Messerchmitt Me 262 Schwalbe was the first production jet fighter. It was a single-place, twin-engine airplane with the engines placed in nacelles under the wings. It was 10.6 meters (34 feet, 9.3 inches) long with a wingspan of 12.51 meters (41 feet, 5.2 inches) and overall height of 3.85 meters (12 feet, 7.6 inches). According to Fay, the fighter’s empty weight was 3,760 kilograms (8,289 pounds) and the maximum gross weight was 7,100 kilograms (15,653 pounds) at engine start.¹

The Me-262 wings had 6° dihedral. The leading edges were swept aft to 20°, while the trailing edges of the inner panels swept forward 8½° to the engine nacelle, then outboard of the engines, aft 5°. The purpose of the sweep was to keep the airplane’s aerodynamic center close to the center of gravity, a technique first applied to the Douglas DC-2. The total wing area was 21.7 square meters (233.6 square feet).

The Me 262 A-1 was powered by two Junkers Jumo TL 109.004 B-1 turbojet engines. The 004 was an axial-flow turbojet with an 8-stage compressor section, six combustion chambers, and single-stage turbine. The 004 engine case was made of magnesium for light weight, but this made it vulnerable to engine fires. The engine was designed to run on diesel fuel, but could also burn gasoline or, more commonly, a synthetic fuel produced from coal, called J2. The engine was first run in 1940, but was not ready for production until 1944. An estimated 8,000 engines were built. The 004 B-1 idled at 3,800 r.p.m., and produced 1,984 pounds of thrust (8.825 kilonewtons) at 8,700 r.p.m. The engine was 2 feet,  inches (0.864 meters) in diameter, 12 feet, 8 inches (3.861 meters) long, and weighed 1,669 pounds (757 kilograms).

During interrogation, Hans Fay said that for acceptance, the production Me 262 was required to maintain a minimum of 830 kilometers per hour (515 miles per hour) in level flight, and 950 kilometers per hour (590 miles per hour) in a 30° dive. The fighter’s cruise speed was 750 kilometers per hour (466 miles per hour).

A number of factors influenced the Me 262’s maximum range, but Fay estimated that the maximum endurance was 1 hour, 30 minutes. U.S. Air Force testing establish the range as 650 miles (1,046 kilometers) and service ceiling at 38,000 feet (11,582 meters).

The Me 262 A-1 was armed with four Rheinmetall-Borsig MK 108 30 mm autocannons with a total of 360 rounds of ammunition. (The Me 262 A-2 had just two autocannons with 160 rounds.) It could also be armed with twenty-four  R4M Orkan 55 mm air-to-air rockets. Two bomb racks under the fuselage could each be loaded with a 500 kilogram (1,102 pounds) bomb.

1,430 Me 262s were produced. They entered service during the summer of 1944. Luftwaffe pilots claimed 542 Allied airplanes shot down with the Me 262.

Hans Fay’s Messerschmitt Me 262 A-1, WNr. 111711, was transported to the United States and was tested at Wright Field, Dayton, Ohio.

711 was lost during a test flight, 20 August 1946, when one of its engines caught fire. The test pilot, Lieutenant Walter J. “Mac” McAuley, Jr., U.S. Army Air Corps, safely bailed out. The Me 262 crashed 2 miles (3.2 kilometers) east of Lumberton, Ohio, and was completely destroyed.

Walter J. McAuley, Jr.,²  was born 10 March 1917 at Fort Worth, Texas. He was the fourth child of Walter J. McAuley and Lola Mahaffey McAuley. Walter attended Texas A&M College at College Station, Texas. While there, he also worked as a mechanic. He graduated with a bachelor of science degree in 1941.

McAuley had brown hair, blue eyes, was 5 feet, 9 inches (1.75 meters) tall and weighed 160 pounds (75.6 kilograms).

McAuley enlisted as a seaman, second class, United States Naval Reserve, and served from 11 April to 3 December 1941. He transferred to the U.S. Army as a private, Air Corps Enlisted Reserve Corps (A.C.E.R.C.), 2 May 1942. Private McAuley was accepted as an aviation cadet, Air Corps, 18 October 1942.

Aviation Cadet McAuley was commissioned as a second lieutenant, Army of the United States (A.U.S.), 29 July 1943, and placed on active duty. He was promoted to first lieutenant, A.U.S., one year later, 1 August 1944.

Lieutenant McAuley was promoted to captain, Air-Reserve, 30 July 1947. On 10 July 1947, he received a permanent commission as a first lieutenant, Air Corps, United States Army. His date of rank was retroactive to 10 March 1945.

After the establishment of the United States Air Force, Lieutenant McAuley was transferred to the new service. He was number 6,626 on the register of Air Force first lieutenants.

McCauley rose to the rank of lieutenant colonel in the U.S. Air Force. He was released from duty 31 December 1962.

Walter J. McAuley Jr., married Miss Mary Elizabeth Sloss, 8 May 1943. They divorced 25 March 1969. He then married Lillian R. Zwickl, 3 April 1969. They also divorced, 10 September 1971.

Lieutenant Colonel McAuley died 11 March 1985. He was buried at Greenwood Memorial Park, Fort Worth, Texas.

11 November 1937: At Augsburg, Germany, Dr.-Ing. Hermann Wurster set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course when he flew a prototype Bayerische Flugzeugwerke AG Bf 109, D-IPKY, to an average speed of 610.95 kilometers per hour (379.63 miles per hour) in four passes over a 3-kilometer course.¹ This broke the speed record set two years earlier by Howard Hughes with his Hughes H-1 Special, NR258Y, by 43.83 kilometers per hour (27.23 miles per hour).²

Bayerische Flugzeugwerke Bf 109 V13 (Bayerische Flugzeugwerke Aktiengesellschaft)

Versuchsflugzeug 13, the BFW Bf 109 V13, Werk-Nr. 1050 (FAI records describe it as a Messerchmitt BF113, and contemporary news reports referred to it as the Messerschmitt BF 113R), was one of four prototypes built from production Junkers Jumo 210-powered Bf 109B airframes to test the Daimler-Benz AG DB 600 engine. It was given a civil registration, D-IPKY. Along with two Bf 109B fighters, V13 was part of an aerial demonstration team which was sent to the International Flying Meeting at Dübendorf, Switzerland, during the last week of July 1937. It was equipped with a Daimler-Benz DB 600 rated at 960 horsepower.

On its return from Switzerland, V13 was prepared for a speed record attempt. It was given a standard drag reduction for racing airplanes, with all its seams filled and sanded smooth, and a coat of paint.

A modified version of the DB 601 engine was installed, reportedly capable of producing 1,660 horsepower for five minutes, with its maximum r.p.m increased from 2,500 to 2,800. It used special Bosch spark plugs. A three-bladed variable-pitch propeller was driven through gear reduction, although the gear ratio is unknown.

Like the Jumo 210, the Daimler-Benz 601 was a liquid-cooled, supercharged, single overhead cam, inverted 60° V-12, though with a much larger displacement. The DB 601 had a displacement of 33.929 liters (2,070.475 cubic inches). An improvement of the DB 600, the 601 series used direct fuel injection rather than a carburetor, and a hydraulically-driven two-speed supercharger.

A production Daimler-Benz DB 601 A had a compression ratio of 6.9:1 and was rated at 1,050 horsepower at 2,400 r.p.m. at 5.2 inches of pounds per square inch (0.36 Bar) of boost, for take-off (1 minute limit). It could produce 970 horsepower at 2,300 r.p.m. with 2.4 pounds per square inch (0.17 Bar) of boost at 12,000 feet (3,658 meters). Its propeller gear reduction ratio was 14:9. The DB 601 A was 67.5 inches (1.715 meters) long, 29.1 inches (0.739 meters) wide, and 40.5 inches (1.029 meters) high. It weighed 1,610 pounds (730.3 kilograms).

The Bf 109E production variant was developed from V13.

In 1938, BFW became Messerschmitt AG. The Bf 109 (also commonly called the Me 109) was produced from 1937 to 1945. Total production was 33,894 aircraft, which amounted to 57% of total fighter production for Germany. Seven plants produced the 109 during World War II. After the war ended, Czechoslovakia produced a variant until 1948. Another Spanish-built variant, the Hispano Aviación HA-1112, remained in production until 1958.

Herman Wurster was born at Stuttgart, Germany, 25 September 1907. In 1926, he began studying aircraft at Königlich Bayerische Technische Hochschule München (TH Munich) and at TH Stuttgart (the Stuttgart Technology Institute of Applied Sciences). He earned a doctorate in engineering (Dr.-Ing.) in 1933. He then became the chief designer for the German Research Institute for Aviation (Deutschen Versuchsanstalt für Luftfahrt) in Berlin.

In 1935 and 1936, Dr.-Ing. Wurster was a test pilot for the Luftwaffe‘s testing site at Rechlin, Mecklenburg, Germany. From 1936 until 1943, he was the chief test pilot for Bayerische Flugzeugwerk and Messerschmitt at Augsburg. From 1943 until the end of the war, Wurster was responsible for the development of Messerschmitt’s rocket-powered surface-to-air guided missile, the Enzian E.1 and its variants.

After the war, Dr.-Ing. Wurster founded a building materials company at Nördlingen, Bavaria. He died in Augsburg 17 October 1985 at the age of 78 years.

15th November, 1940.

ROYAL AIR FORCE.

The KING has been graciously pleased to confer the Victoria Cross on the undermentioned officer in recognition of most conspicuous bravery : —

Flight Lieutenant James Brindley NICOLSON (39329) — No. 249 Squadron.

During an engagement with the enemy near Southampton on 16th August, 1940, Flight Lieutenant Nicolson’s aircraft was hit by four cannon shells, two of which wounded him whilst another set fire to the gravity tank. When about to abandon his aircraft owing to flames in the cockpit he sighted an enemy fighter. This he attacked and shot down, although as a result of staying in his burning aircraft he sustained serious burns to his hands, face, neck and legs.

Flight Lieutenant Nicolson has always displayed great enthusiasm for air fighting and this incident shows that he possesses courage and determination of a high order. By continuing to engage the enemy after he had been wounded and his aircraft set on fire, he displayed exceptional gallantry and disregard for the safety of his own life.

Peter Townsend wrote about Nick Nicolson’s battle in his history of the Battle of Britain, Duel of Eagles:

Flight Lieutenant Eric J.B. Nicolson, VC, RAF (Detail from photograph by Stanley Devon, Royal Air Force official photographer. Imperial War Museum CH 1700 4700-16)

“Flight Lieutenant J.B. Nicolson of 249 Squadron was patrolling in his Hurricane west of Tangmere at seventeen thousand feet. He dived on some Ju. 88s when suddenly his Hurricane staggered. From somewhere behind bullets and cannon shells ripped through the hood, hit him in the foot and pierced his centre-tank. A searing mass of flame filled the cockpit. As he whipped into a steep turn he saw the offender, a Me. 110, slide below, diving hard. A wild resolve, stronger than reason, seized Nicolson. The cockpit a furnace, his dashboard ‘dripping like treacle’ and his hands fused by heat onto throttle and stick, he yelled, ‘I’ll get you, you Hun.’ And he went firing until the Me. 110 fell, until the frightful agony of his burns had passed the threshold of feeling. Then he struggled out of the cockpit and still wreathed in flames fell until the rush of cold air extinguished them. Only then did his mutilated hand fumble for the ripcord and somehow find strength to pull it. As if his sufferings were not already enough, some imbecile of a Home Guard fired at Nicolson and hit him fifty feet above the village of Millbrook in Hampshire.

“The gallant Nicolson was awarded the Victoria Cross. Of three thousand fighter pilots who fought in the battle ‘to defend the cause of civilization’ Nicolson alone among the defenders received the supreme award for valour. It was enough. The twenty-three-year-old pilot was typical of his young comrades. Alone in their tiny cockpits miles above the earth, there courage was of a peculiar kind which no medal, no material standard, could ever properly measure.”

Nick Nicolson’s fighter was a Hawker Hurricane Mk.I, P3576, with squadron markings GN A. It was in the third production block of 544 Hurricanes built by Hawker Aircraft Limited,  Brooklands, between February and July 1940.

The Hurricane Mk.I was ordered into production in the summer of 1936. The first production airplane flew on 12 October 1937. The early production Hurricane Mk. I retained the wooden fixed-pitch propeller and fabric-covered wings of the prototype, though this would change with subsequent models. It was 31 feet, 4 inches (9.550 meters) long with a wingspan of 40 feet (12.192 meters) and overall height of 13 feet, 3 inches (4.039 meters). Its empty weight was 4,982 pounds (2,260 kilograms) and gross weight was 6,750 pounds (3,062 kilograms).

The Mk.I’s engine was a liquid-cooled, supercharged, 27.01 liter (1,648.96 cubic inches) Rolls-Royce R.M.1.S. Merlin Mk.III single-overhead-cam 60° V-12, rated at 990 horsepower at 2,600 r.p.m. at 12,250 feet (3,734 meters), and 1,030 horsepower at 3,000 r.p.m., at 10,250 feet (3,124 meters), using 87 octane aviation gasoline. The Merlin III drove the propeller through a 0.477:1 gear reduction ratio. It weighed 1,375 pounds (624 kilograms).

The fixed-pitch propeller was soon replaced with a three-bladed, two-pitch propeller, and then a three-bladed constant-speed propeller. Speed trials of a Mk.I equipped with a 10 foot, 9 inch (3.277 meters) diameter Rotol constant-speed propeller achieved a maximum True Air Speed in level flight of 316 miles per hour (509 kilometers per hour) at 17,750 feet (5,410 meters) at 3,000 r.p.m. The service ceiling was 33,750 feet (10,287 meters). The Mk.I’s range was 600 miles (966 kilometers) at 175 miles per hour (282 kilometers per hour).

The fighter was armed with eight Browning .303-caliber Mark II machine guns mounted in the wings.

At the beginning of World War II, 497 Hurricanes had been delivered to the Royal Air Force, enough to equip 18 squadrons. During the Battle of Britain, the Hurricane accounted for 55% of the enemy aircraft destroyed. Continuously upgraded throughout the war, it remained in production until 1944. A total of 14,503 were built by Hawker, Gloster and the Canadian Car and Foundry Company.

Eric James Brindley Nicolson was born 29 April 1917 at Hampstead, London, England. His parents were Leslie Gibson Nicolson and Dorothea Hilda Ellen Brindley. He was educated at the Tonbridge School in Kent, a private school which was founded in 1553. Nicolson was employed as an experimental engineer at Sir Henry Ricardo’s Engine Patents, Ltd.,  Shoreham, West Sussex, until joining the Royal Air Force in October 1936. On 21 December 1936, he was commissioned as a Pilot Officer. After flight training, P/O Nicolson served with No. 72 Squadron at RAF Church Fenton, North Yorkshire, August 1937–May 1940. He was promoted to Flying Officer, 12 May 1939.

On 29 July 1939, Eric Nicolson was married to Miss Muriel Caroline Kendall of Kirby Wharfe, Yorkshire.

Flying Officer Nicolson was assigned to No. 249 Squadron at RAF Leconfield, East Riding of Yorkshire, 15 May 1940, as an acting flight commander, and then promoted to Flight Lieutenant, 3 September 1940.

Following the action of 16 August, Flight Lieutenant Nicolson was hospitalized at the burn unit of Princess Mary’s Hospital, RAF Halton, Buckinghamshire, and then sent to a convalescent facility at Torquay, Devon. On 12 January 1941, he was promoted to Squadron Leader.

Nicolson returned to duty 24 February 1941, with 54 Operational Training Unit. From 21 September 1941 to 16 March 1942, he commanded No. 1459 Flight at RAF Hibaldstow, Lincolnshire. This was a night fighter unit, flying the Douglas Boston (P-70 Havoc). He was next assigned as a staff officer at Headquarters, 293 Wing, Royal Air Force, Alipore, West Bengal, India. After another staff assignment, Squadron Leader Nicolson was given command of 27 Squadron, a de Havilland Mosquito squadron at Agartala, in northeast India.

Nick Nicolson was promoted to Wing Commander 11 August 1944 and assigned to 3rd Tactical Air Force Headquarters in the Comilla Cantonment, East Bengal.

Wing Commander Eric James Brindley Nicolson, V.C., D.F.C., died 2 May 1945, while flying as an observer aboard a No. 355 Squadron Consolidated Liberator B Mk.VI, KH210, “R” (B-24J-85-CF 44-44071). At approximately 0250 hours, two engines caught fire. The bomber, piloted by Squadron Leader G.A. De Souza, RAF, and Flight Sergeant Michael Henry Pullen, Royal Australian Air Force, ditched in the Bay of Bengal, approximately 130 miles (209 kilometers) south of Calcutta. Of the eleven on board, only Pullen and one of the gunners survived.

Nicolson was the only RAF Fighter Command pilot awarded the Victoria Cross during World War II.

18 July 1942: In the late 1930s, Germany began developing a fighter powered by a turbojet engine. In early 1942 the first two prototypes of the Messerschmitt Me 262 began flight testing. They had two BMW 003 jet engines mounted on the wings, but for safety, a piston engine and propeller were mounted in the nose.

At 8:40 a.m. on 18 July 1942, V3, the third prototype, call sign PC+UC, made its first pure-jet flight when it took off from Leipheim, Bavaria, with Messerschmitt’s Chief Test Pilot, Flugkapitän Fritz Wendel. (The first true turbojet-powered aircraft, the Heinkel He 178 V-1, first flew almost three years earlier, 27 August 1939).

This prototype was powered by two Junkers Jumo 004 turbojet engines. The Jumo 004 had an eight-stage axial flow compressor, six straight through combustion chambers and a single-stage turbine. It produced 1,850 pounds of thrust (8.23 kilonewtons).

There were problems created by the airplane’s use of a tailwheel configuration. Turbulence from the wings and reflected jet exhaust blanked out the tail surface. When the Me 262 prototype reached flying speed, Wendel tapped the brakes. The tail popped up, free of the turbulence, and the jet fighter took off. Beginning with the fifth prototype, V5, all Me 262s were built with tricycle landing gear.

The Messerchmitt Me 262 Schwalbe was the first production jet fighter, preceding the British Gloster Meteor Mk.III into operational service by about three months. It was a single-place, twin-engine airplane with the engines placed in nacelles under the wings. It was 10.6 meters (34 feet, 9.3 inches) long with a wingspan of 12.51 meters (41 feet, 5.2 inches) and overall height of 3.85 meters (12 feet, 7.6 inches). According to Fay, the fighter’s empty weight was 3,760 kilograms (8,289 pounds) and the maximum gross weight was 7,100 kilograms (15,653 pounds) at engine start.¹

The Me-262 wings had 6° dihedral. The leading edges were swept aft to 20°, while the trailing edges of the inner panels swept forward 8½° to the engine nacelle, then outboard of the engines, aft 5°. The purpose of the sweep was to keep the airplane’s aerodynamic center close to the center of gravity, a technique first applied to the Douglas DC-2. The total wing area was 21.7 square meters (233.6 square feet).

Messerschmitt test pilot Hans Fay told Allied interrogators that, for acceptance, the production Me 262 was required to maintain a minimum of 830 kilometers per hour (515 miles per hour) in level flight, and 950 kilometers per hour (590 miles per hour) in a 30° dive. The fighter’s cruise speed was 750 kilometers per hour (466 miles per hour).

A number of factors influenced the Me 262’s maximum range, but Fay estimated that the maximum endurance was 1 hour, 30 minutes. U.S. Air Force testing establish the range as 650 miles (1,046 kilometers) and service ceiling at 38,000 feet (11,582 meters).

The Jumo 004 was tested at the NACA Aircraft Engine research Laboratory, Cleveland, Ohio, in March 1946. (NASA)

The Me 262 A-1 was powered by two Junkers Jumo TL 109.004 B-1 turbojet engines. The 004 was an axial-flow turbojet with an 8-stage compressor section, six combustion chambers, and single-stage turbine. The 004 engine case was made of magnesium for light weight, but this made it vulnerable to engine fires. The engine was designed to run on diesel fuel, but could also burn gasoline or, more commonly, a synthetic fuel produced from coal, called J2. The engine was first run in 1940, but was not ready for production until 1944. An estimated 8,000 engines were built. The 004 B-1 idled at 3,800 r.p.m., and produced 1,984 pounds of thrust (8.825 kilonewtons) at 8,700 r.p.m. The engine was 2 feet, inches (0.864 meters) in diameter, 12 feet, 8 inches (3.861 meters) long, and weighed 1,669 pounds (757 kilograms).
