5 October 1954: Chief Engineering Test Pilot Tony LeVier made the first flight in the second prototype Lockheed XF-104 Starfighter, 53-7787, at Edwards Air Force Base in the high desert of southern California. This was the armament test aircraft and was equipped with a General Electric T171 Vulcan 20mm Gatling gun. This six-barreled gun was capable of firing at a rate of 6,000 rounds per minute.
The XF-104 was 49 feet, 2 inches (14.986 meters) long with a wingspan of 21 feet, 11 inches (6.680 meters) and overall height of 13 feet, 6 inches (4.115 meters). The prototypes had an empty weight of 11,500 pounds (5,216 kilograms) and maximum takeoff weight of 15,700 pounds (7,121 kilograms).
While the first prototype, 53-7776, was equipped with a Buick J65-B-3 turbojet engine, the second used a Wright Aeronautical Division J65-W-6 with afterburner. Both were improved derivatives of the Armstrong Siddely Sa.6 Sapphire, built under license. The J65 was a single-shaft axial-flow turbojet with a 13-stage compressor and 2-stage turbine. The J65-B-3 was rated at 7,330 pounds of thrust, and the J65-W-6, rated at 7,800 pounds (34.70 kilonewtons), and 10,500 pounds (46.71 kilonewtons) with afterburner.
The XF-104 had a maximum speed of 1,324 miles per hour (2,131 kilometers per hour), a range of 800 miles (1,287 kilometers) and a service ceiling of 50,500 feet (15,392 meters).
53-7787 was lost 19 April 1955 when it suffered explosive decompression at 47,000 feet (14,326 meters) during a test of the T171 Vulcan gun system. The lower escape hatch had come loose due to an inadequate latching mechanism. Lockheed test pilot Herman R. (“Fish”) Salmon was unable to find a suitable landing area and ejected at 250 knots (288 miles per hour/463 kilometers per hour) and 15,000 feet (4,572 meters). The XF-104 crashed 72 miles (117 kilometers) east-northeast of Edwards Air Force Base. Salmon was found two hours later, uninjured, about 2 miles (3.2 kilometers) from the crash site.
The YF-104A pre-production aircraft and subsequent F-104A production aircraft had many improvements over the two XF-104 prototypes. The fuselage was lengthened 5 feet, 6 inches (1.68 meters). The J65 engine was replaced with a more powerful General Electric J79-GE-3 turbojet. There were fixed inlet cones added to control airflow into the engines. A ventral fin was added to improve stability.
27 July 1934: While Ellen Evalyn Church is recorded as the first airline flight attendant, or “stewardess,” Fräulein Nelly Hedwig Diener was Europe’s first airline hostess. At the age of 22 years, she began flying for Swissair Schweizerische Luftverkehr-AG on 1 May 1934. She was known as the Engel der Lüfte (“Angel of the Skies”).
Her 79th flight departed Zürich-Dübendorf Airport enroute Stuttgart-Echterdingen Airport and then on to Berlin. The pilot was Armin Mühlematter and radio operator/navigator was Hans Daschinger. There were nine passengers on board.
The airliner was a Curtiss-Wright Airplane Division AT-32C Condor II, a one-of-a-kind variant of the AT-32 which was built specifically for Swissair. It carried identification number CH-170 on its wings and fuselage. The airliner was registered HB-LAP.
The Condor was flying in a thunderstorm at approximately 3,000 meters (9,843 feet) when the right wing structure failed and separated from the airplane. CH-170 crashed into a forest between Wurmlingen and Tuttlingen, Germany, and caught fire. All twelve persons aboard were killed.
Investigators found that a fracture had developed in the welded structure of the engine mount and wing. It was believed that it was caused by defective construction and welding techniques combined with vibration of the engine. A second fracture was caused by the violent weather.
This accident was the first for Swissair, the national airline of Switzerland.
CH-170 was one of 45 T-32 Condor II airplanes built by Curtiss-Wright for use as both a civil transport and a military transport or bomber. It was a twin-engine, two-bay biplane with retractable landing gear. CH-170 was purchased by Swissair 11 April 1934, and entered service 28 March 1934. The airliner was configured with 15 passenger seats.
The AT-32C was 49 feet, 1-1/8 inch (14.049 meters) long with an upper wingspan of 85 feet, 0 inches (25.908 meters) and lower wing span of 74 feet, 0 inches (22.555 meters), and height of 16 feet, 4 inches (4.953 meters). Both wings had a chord of 8 feet, 10.5 inches (2.705 meters). The total wing area was 1,331 square feet (123.65 square meters). The vertical gap between the upper and lower wings was 9 feet, 11 inches (3.023 meters). There was no stagger. Upper and lower wings had an angle of incidence of 1°. The center sections were straight, but outboard of the engines, they had 2¼° dihedral. ¹
CH-170 had an empty weight of 11,446 pounds (5,192 kilograms) and gross weight of 16,800 pounds (7,620 kilograms).
The AT-32C was powered by two air-cooled, supercharged, 1,823.129-cubic-inch-displacement (29.875 liter) Wright Cyclone SR-1820-F3 ² single-row nine-cylinder radial engines with a compression ratio of 6.4:1. They were rated at 675 horsepower at 1950 r.p.m., each, and required 87-octane aviation gasoline. These were direct-drive engines, turning three-bladed variable-pitch propellers. The SR-1820-F3 was 3 feet, 7.375 inches (1.102 meters) long, 4 feet, 5.75 inches (1.365 meters) in diameter and weighed 937 pounds (425 kilograms). The engines were enclosed in NACA cowlings, rather than the Townend rings of earlier T-32-series airplanes.
The AT-32C had a cruising speed of 235 kilometers per hour (146 miles per hour) and maximum speed of 274 kilometers per hour (170 miles per hour). The service ceiling was 4,000 meters (13,123 feet) and its range was 800 kilometers (497 miles).

10–14 July 1938: Howard Robard Hughes, Jr., along with a crew of four, departed Floyd Bennett Field, Brooklyn, New York, on a flight to circle the Northern Hemisphere. His airplane was a Lockheed Super Electra Special, Model 14-N2, registered NX18973. Aboard were Harry P. McLean Connor, co-pilot and navigator; 1st Lieutenant Thomas Lawson Thurlow, United States Army Air Corps, navigator; Richard R. Stoddart, a field engineer for the National Broadcasting Company (NBC), radio operator; Edward Lund, flight engineer. Lieutenant Thurlow was the Air Corps’ expert on aerial navigation. Stoddart was an expert in radio engineering. Thurlow, Stoddart and Lund were also rated pilots.
Before they took off from Floyd Bennett Field, the Lockheed was christened New York World’s Fair 1939, in keeping with an agreement that Hughes had made with Grover Whalen and the fair’s organizers.
Howard Hughes and his crew departed Floyd Bennett Field at 7:19:10 p.m. on 10 July. The route of the flight was from Floyd Bennett Field to Le Bourget Aerodrome, Paris, France, a distance of 3,641 miles (5,860 kilometers), flown in an elapsed time of 16 hours, 38 minutes; Moscow, Russia, USSR, 1,640 miles (2,639 kilometers), 7:51; Omsk, Siberia, 1,400 miles (2,253 kilometers), 7:27; Yakutsk, Yakut ASSR, 2,158 miles (3,473 kilometers), 10:31; Fairbanks, Alaska, 2,457 miles (3,954 kilometers), 12:17; Minneapolis, Minnesota, 2,441 miles (3,928 kilometers), 12:02; and back to Floyd Bennett Field, 1,054 miles (1,696 kilometers) 4:26.
They arrived at Floyd Bennett Field at 2:34 p.m., 14 July. The distance flown was approximately 14,800 miles (23,818 kilometers) (sources differ). The total duration was 91 hours, 14 minutes, 10 seconds. The actual flight time was 71 hours, 11 minutes, 10 seconds. Average speed for the flight was 206.1 miles per hour (331.7 kilometers per hour).
The international organization for flight records, the Fédération Aéronautique Internationale, requires that a circumnavigation cross all meridians in one direction and be at least the length of the Tropic of Cancer, 22,858.729 miles (36,787.559 kilometers). Howard Hughes’ “around the world flight” circled the Northern Hemisphere and was at least 8,058 miles (12,968 kilometers) short of the required distance, so no official record was set. (The same is true of Wiley H. Post’s two earlier “around the world” flights which used a similar route.)
The National Aeronautic Association awarded the Aero Club Trophy (after 1944, known as the Robert J. Collier Trophy, or simply, The Collier Trophy) to Howard Hughes and his associates, “For their epoch making round the world flight in 91 hours and 14 minutes.” The Collier is an annual award, “. . . for the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year.”
The Lockheed Super Electra 14-N2, serial number 1419, was offered to Hughes by the Lockheed Aircraft Company, Burbank, California, at no cost.
Company officials believed that publicity generated by an around-the-world flight would justify the expense. The airplane underwent modification for two months at the Burbank factory. The Curtiss-Wright Corporation provided new engines. Fuel capacity was increased to 1,844 gallons (6,980.3 liters). Three radio systems were installed.
The Lockheed Model 14 Super Electra was an all-metal, twin-engine, low-wing monoplane with retractable landing gear, designed as a medium-sized airliner. It was flown by two pilots and could carry up to 12 passengers. Based on aerodynamic studies carried out by Clarence L. “Kelly” Johnson on the earlier Model 10 Electra, the airplane was configured with an “H-tail”, with vertical fins and rudders placed at the ends of the horizontal stabilizer. This was a characteristic design feature for Lockheed aircraft through the 1950s.
The Model 14 was 44 feet, 4 inches (13.513 meters) long with a wingspan of 65 feet, 6 inches (19.964 meters) and overall height of 11 feet, 5 inches (3.480 meters). Hughes’ Model 14-N2 Special differed, but a Model 14-WF-62 airliner version had an empty weight of 10,750 pounds (4,876 kilograms), gross weight of 15,650 pounds (7,098 kilograms) and maximum takeoff weight of 17,500 pounds (7,938 kilograms). The airliner had maximum speed of 250 miles per hour (402 kilometers per hour) and a service ceiling of 24,500 feet (7,468 meters).
NX18973 was powered by two air-cooled, supercharged, 1,823.129-cubic-inch-displacement (29.875 liter) Wright Aeronautical Division Cyclone GR-1820-G102 nine-cylinder radial engines with a normal power rating of 900 horsepower at 2,200 r.p.m., and 1,100 horsepower at 2,200 r.p.m for take-off. The engines had a compression ratio of 6.7:1 and required 91-octane gasoline. They turned three-bladed Hamilton Standard constant-speed propellers through a 0.6875:1 gear reduction. The GR-1820-102 was 4 feet, 0.12 inches (1.222 meters) long, 4 feet, 7.10 inches (1.400 meters) in diameter, and weighed 1,275 pounds (578 kilograms).
Representative performance figures are maximum speed of 250 miles per hour (402 kilometers per hour) and a service ceiling of 24,500 feet (7,468 meters). NX19783 had an estimated maximum range of 4,500 miles (7,242 kilometers).
Following Hughes’ flight, NX18973 was returned to Lockheed. The manufacturer then sold the Super Electra to the Royal Canadian Air Force. It was assigned fuselage identification AX688. (A militarized version of the Super Electra was produced as the Hudson light bomber.)
On 10 November 1940, the Super Electra took off from Nairobi, Kenya, on a transcontinental ferry flight to from South Africa to Egypt. There were high winds and it was raining. After climbing to 500 feet (152 meters) AGL, the Lockheed banked to the left. It stalled, entered a spin and crashed. The wreck caught fire. All persons on board were killed.
2 July 1943: 1st Lieutenant Charles Blakesly Hall, United States Army Air Corps, of the 99th Fighter Squadron (which was briefly attached to the 324th Fighter Group) was the first of the famous “Tuskegee Airmen” to shoot down an enemy airplane during World War II. At the time the 99th was based at El Haouaria Airfield on the coast of Tunisia and was patrolling the island of Sicily. The squadron’s primary mission was ground attack.
On 2 July, the 99th was escorting North American Aviation B-25 Mitchell medium bombers near Castelventrano, in western Sicily. Enemy fighters intercepted the flight.
It was my eighth mission and the first time I had seen the enemy close enough to shoot him. I saw two Focke-Wulfs following the bombers just after the bombs were dropped. I headed for the space between the fighters and bombers and managed to turn inside the Jerries. I fired a long burst and saw my tracers penetrate the second aircraft. He was turning to the left, but suddenly fell off and headed straight into the ground. I followed him down and saw him crash. He raised a big cloud of dust.
Lieutenant Hall was officially credited with destroying a Focke-Wulf Fw 190,¹ the most effective Luftwaffe fighter of World War II. Not only was Lieutenant Hall’s victory the first for the squadron, but it was also the only enemy airplane to have been shot down by the 99th Fighter Squadron during 1943.
Charles Blakesly Hall was the second child of Franklin Hall, a 30-year-old kiln-burner from Mississippi, and Anna Blakesly Hall, 25 years old, and also from Mississippi. Charles was born 25 August 1920 at his parents home, 742 N. Columbia Street, Brazil, Indiana. He graduated from Brazil High School in 1938 and then attended Eastern Illinois University. He majored in Pre-Med, and was active in sports. Hall worked as a waiter while attending college.
After three years of college, on 12 November 1941, Hall enlisted as an Aviation Cadet, Air Corps, United States Army, at Fort Benjamin Harrison, Lawrence, Indiana. Military records indicate that he stood 5 feet, 7 inches tall (170 centimeters) and weighed 150 pounds (68 kilograms).
Charles Hall was part of a group of African-American airmen that would be known as the Tuskegee Airmen. They were initially trained at the Tuskegee Institute, Tuskegee, Alabama, an all-black college which had been established in 1881 by Booker T. Washington. Initial flight training was conducted at Moton Field, a few miles away, and the cadets transitioned into operational aircraft at Tuskegee Army Air Field. Additional flight trained took place at Cochran Field, near Montgomery, Alabama.
On completion of training, Charles B. Hall was commissioned as a second lieutenant, U.S. Army Air Corps, on 3 July 1942. (Serial number 0790457)
Lieutenant Charles B. Hall married Miss Maxine Jessie Parish, a stenographer, in Vigo County, Indiana, 14 December 1942.
The 99th Fighter Squadron was the first unit to be assigned overseas. It was sent to North Africa, 2 April 1943, as part the 33rd Fighter Group.
The 99th Fighter Squadron was the first unit to be assigned overseas. It was sent to North Africa, 2 April 1943, as part the 33rd Fighter Group.
Hall was the first African-American to be awarded the Distinguished Flying Cross. Before the war ended, he had flown 198 combat missions and had been promoted to the rank of major.
Major Hall transferred to the Air Force Reserve. He worked at Tinker Air Force Base, Oklahoma City, as a civil service employee from 1949 until retiring in 1967. He then worked at the Federal Aviation Administration.
Hall later married Miss Lola Delois Miles of Oklahoma City. They had two children and remained together until his death, 22 November 1971.
Major Charles Blakesly Hall, United States Air Force (Retired), was buried at Hillcrest Memorial Gardens, Oklahoma City, Oklahoma.
Charles Hall’s fighter was a Curtiss-Wright P-40L-15-CU Warhawk, 42-10895. The P-40L (Curtiss-Wright Model 87-B3) differed from the majority of P-40s in that it was powered by a Packard V-1650-1 Merlin engine instead of the Allison V-1710.
The P-40L was a lightened version of the P-40F, with fuel tanks removed from the wings, and armament reduced from six to four Browning AN-M2 .50-caliber machine guns, with only 201 rounds of ammunition per gun. Identifying features of the P-40F and P-40L are the absence of a carburetor intake on the top of the engine cowling, a very deep radiator scoop below the propeller spinner, and a fuselage lengthened 2 feet, 2 inches (0.660 meters).
The P-40L was 33 feet, 3-23/32 inches (10.15286 meters) long with a wingspan of 37 feet, 3½ inches (11.36650 meters) and height of 10 feet, 7-25/32 inches (3.24564 meters). The fighter’s empty weight was approximately 6,870 pounds (3,116 kilograms) and the gross weight was 9,416 pounds (4,271 kilograms).
The V-1650-1 was the first version of the Rolls-Royce Merlin to be built under license by the Packard Motor Car Company of Detroit, Michigan. It was developed from the Merlin XX and designated Merlin 28. The Packard V-1650-1 was a right-hand tractor, liquid-cooled, supercharged, 1,649-cubic-inch-displacement (27.04-liter) single overhead cam (SOHC) 60° V-12 engine. It had a compression ratio of 6.0:1, and required 100-octane aviation gasoline. It was rated at 1,080 horsepower at 2,650 r.p.m., and 1,300 horsepower at 3,000 r.p.m. for takeoff. The Military Power rating was 1,240 horsepower at 3,000 r.p.m. at 11,500 feet (3,505 meters), and 1,120 horsepower at 18,500 feet (5,639 meters). The engine drove an 11-foot (3.353 meter) diameter, three-bladed Curtiss Electric constant-speed propeller through a 0.477:1 gear reduction. The V-1650-1 weighed 1,512 pounds (686 kilograms).
The P-40L had a maximum speed of 368 miles per hour (592 kilometers per hour).
Curtiss-Wright built 13,738 P-40-series aircraft. 3,866 of these were the P-40L variant.
¹ A study of U.S. Army Air Force claims of enemy aircraft destroyed (Andrew Arthy and Morten Jessen, 2013) indicates that no Focke Wulf Fw 190s were present at the time, however, Messerchmitt Bf 109s of Jagdgeschwader 77 were defending the target against B-25s and P-40s. Two were lost on that day. The authors suggest that opposing aircraft were often misidentified.
27 June 1952: The Bell X-2 research rocketplane, with company test pilot Jean Leroy (“Skip”) Ziegler at the controls, was airdropped from a “mothership,” a Boeing B-50A-5-BO Superfortress, 46-011, over Edwards Air Force Base, California. This was the first flight of the X-2 Program, and was an unpowered glide flight for pilot familiarization.
On touch down, the nose wheel collapsed and the aircraft slid across the dry lake bed, but was not seriously damaged.
Two X-2 rocketplanes, serial numbers 46-674 and 46-675, were built by the Bell Aircraft Corporation, which has also built the X-1 series. The second X-2 was the first one to fly.
The X-2 was a joint project of the U.S. Air Force and NACA (the National Advisory Committee for Aeronautics, the predecessor of NASA). The rocketplane was designed and built by Bell Aircraft Corporation of Buffalo, New York, to explore supersonic flight at speeds beyond the capabilities of the earlier Bell X-1 and Douglas D-558-2 Skyrocket. In addition to the aerodynamic effects of speeds in the Mach 2.0–Mach 3.0 range, engineers knew that the high temperatures created by aerodynamic friction would be a problem, so the aircraft was built from Stainless Steel and K-Monel, a copper-nickel alloy.
The Bell Aircraft Corporation X-2 was 37 feet, 10 inches (11.532 meters) long with a wingspan of 32 feet, 3 inches (9.830 meters) and height of 11 feet, 10 inches (3.607 meters). Its empty weight was 12,375 pounds (5,613 kilograms) and loaded weight was 24,910 pounds (11,299 kilograms).
The X-2 was powered by a throttleable Curtiss-Wright XLR25-CW-1 rocket engine that produced 2,500–15,000 pounds of thrust burning alcohol and liquid oxygen. Rather than use its limited fuel capacity to take off and climb to altitude, the X-2 was dropped from a modified heavy bomber as had been the earlier rocketplanes. The launch altitude was 30,000 feet (9,144 meters). After the fuel was exhausted, the X-2 glided to a touchdown on Rogers Dry Lake at Edwards Air Force Base.
A four-engine Boeing B-50A Superfortress bomber, serial number 46-011, was modified as the ”mothership.” A second Superfortress, B-50D-95-BO 48-096, was also modified to carry the X-2, and was redesignated EB-50D. During the flight test program, the X-2 reached a maximum speed of Mach 3.196 (2,094 miles per hour, 3,370 kilometers per hour) and a maximum altitude of 126,200 feet (38,466 meters).
On 12 May 1953, less than one year after the first glide flight, Skip Ziegler was in the cockpit of 46-675 while it was being carried on a captive test flight aboard the B-50A Superfortress. An internal explosion destroyed the X-2 and killed Ziegler and another crewman aboard the mothership. The rocketplane fell into Lake Ontario and neither it nor Ziegler’s body were ever recovered. The Superfortress was able to land, but was so badly damaged that it never flew again.
