The flight profiles for the record attempts were developed by McDonnell Douglas Chief Developmental Test Pilot, Charles P. “Pete” Garrison (Lieutenant Colonel, U.S. Air Force, Retired).

Streak Eagle carried only enough fuel for each specific flight. It was secured to the hold-back device on the runway and the engines were run up to full afterburner. It was released from the hold-back and was airborne in just three seconds.

Screen Shot 2016-01-15 at 21.10.22When the F-15 reached 428 knots (793.4 kilometers per hour), the pilot pulled up into an Immelmann turn, holding 2.5 Gs. Streak Eagle would arrive back over the air base in level flight at about 32,000 feet (9,754 meters), but upside down. Rolling right side up, Streak Eagle continued accelerating to Mach 1.5 while climbing through 36,000 feet (10,973 meters). It would then accelerate to Mach 2.2 and the pilot would pull the fighter up at 4.0 Gs until it reached a 60° climb angle. He held 60° until he had to shut down the engines to prevent them from overheating in the thin high-altitude atmosphere.

After reaching a peak altitude and slowing to just 55 knots (63 miles per hour, 102 kilometers per hour), the airplane was pushed over into a 55° dive. Once it was below 55,000 feet (16,764 meters) the engines would be restarted and Streak Eagle returned to land at Grand Forks.

Streak Eagle is a very early production F-15A-6-MC Eagle, a single-seat, twin-engine air superiority fighter. It is 63 feet, 9.0 inches (19.431 meters) long with a wingspan of 42 feet, 9.7 inches (13.048 meters) and overall height of 18 feet, 5.4 inches (5.624 meters). The F-15A has an empty weight of 25,870 pounds (11,734 kilograms) and its maximum takeoff weight (MTOW) is 44,497 pounds (20,184 kilograms).

The F-15A is powered by two Pratt & Whitney JTF22A-25A (F100-PW-100) afterburning turbofan engines. The F100 is a two-spool, axial-flow turbine engine with a 3-stage fan section; 10-stage compressor; single chamber combustion section; and 4-stage turbine (2 low- and 2 high-pressure stages). The engine has a Maximum Continuous Power rating of 12,410 pounds of thrust (55.202 kilonewtons); 14,690 pounds (65.344 kilonewtons, 30-minute limit; and a maximum 23,840 pounds (106.046 kilonewtons), 5-minute limit. The F100-PW-100 is 191 inches (4.851 meters) long, 46.5 inches (1.181 meters) in diameter, and weighs 3,035 pounds (1,376.7 kilograms).

The cruise speed of the F-15A Eagle is 502 knots (578 miles per hour/930 kilometers per hour). It has a maximum speed of 893 knots (1,028 miles per hour/1,654 kilometers per hour) at 10,000 feet (3,048 meters), and 1,434 knots (1,650 miles per hour/2,656 kilometers per hour) at 45,000 feet (13,716 meters). The ceiling is 63,050 feet (19,218 meters) at maximum power. It can climb at an initial 67,250 feet per minute (342 meters per second) from Sea Level, and with a thrust-to-weight ratio of 1.15:1, The F-15 can climb straight up. The Eagle’s combat radius is 638 nautical miles (734 statute miles/1,182kilometers).

The F-15A is armed with one General Electric M61A1 Vulcan 20mm rotary cannon with 938 rounds of ammunition, four AIM-7 Sparrow radar-guided missiles and four AIM-9 Sidewinder heat-seeking missiles.

384 F-15A Eagles were built before production shifted to the improved F-15C version. As F-15Cs became operation, the F-15As were transferred to Air National Guard units assigned to defend continental U.S. airspace. The last F-15A was retired from service in 2009.

Streak Eagle was specially modified for the record attempts. Various equipment that would not be needed for these flights was eliminated: The flap and speed brake actuators, the M61A1 Vulcan 20 mm cannon and its ammunition handling equipment, the radar and fire control systems, unneeded cockpit displays and radios, and one generator.

Other equipment was added: A long pitot boom was mounted at the nose with alpha and beta vanes, equipment for the pilot’s David Clark Company A/P-225-6 full pressure suit, extremely sensitive accelerometers and other instrumentation, extra batteries, an in-cockpit video camera aimed over the pilot’s shoulder, and perhaps most important, a special hold-down device was installed in place of the fighter’s standard arresting hook.

These changes resulted in an airplane that was approximately 1,800 pounds (817 kilograms) lighter than the standard production F-15A. This gave it a thrust-to-weight ratio of 1.4:1.

Because Streak Eagle was a very early production airplane its internal structure was weaker than the final production F-15A standard. It was considered too expensive to modify it to the new standard, so it was transferred to the National Museum of the United States Air Force at Wright-Patterson Air Force Base, Ohio, in December 1980.

14 December 1959: Air Force test pilot Captain Joe Bailey Jordan, United States Air Force, established a Fédération Aéronautique Internationale (FAI) World Record for Altitude in a Turbojet Aircraft, breaking a record set only 8 days before by Commander Lawrence E. Flint, Jr., U.S. Navy, flying the number two prototype McDonnell YF4H-1 Phantom II, Bu. No. 142260.¹

Flying a slightly modified Lockheed F-104C-5-LO Starfighter, 56-885, (the aft fuselage had been replaced by one from a two-place F-104B, which had larger tail surfaces), Jordan released the brakes at Edwards Air Force Base, and 15 minutes, 4.92 seconds later he reached 30,000 meters (98,425 feet) establishing an Fédération Aéronautique Internationale (FAI) world record for time-to-altitude.² The Starfighter continued the zoom climb profile, peaking at 103,389 feet (31,513 meters) ³ and going over the top at 455 knots (843 kilometers per hour). While accelerating for the zoom maneuver, Jordan’s F-104 reached Mach 2.36.

The Harmon International Trophy (NASM)

Fédération Aéronautique Internationale rules required that a new record must exceed the previous record by 3%. The Starfighter beat the Phantom II’s peak altitude by 4.95%. Captain Jordan was credited for his very precise flying and energy efficiency. For this flight, Captain Jordan was awarded the Harmon International Trophy.

Joe Bailey Jordan was born at Huntsville, Texas, 12 June 1929, the son of James Broughtan Jordan, a track foreman, and Mattie Lee Simms Jordan. He entered the Air Force in 1949, trained as a pilot and received his pilot’s wings 15 September 1950. He flew the Lockheed F-80 Shooting Star during the Korean War, and served as a flight instructor after his return to the United States. He was a graduate of both the Air Force Test Pilot School and the Air Force Fighter Weapons School. He became a project test pilot on the F-104 in 1956.

Jordan married Dolores Ann Craig of Spokane, Washington, 8 February 1958, at Santa Monica, California. They had two children, Carrie and Ken.

Colonel Jordan was the first Western pilot to fly the Mikoyan-Gurevich MiG-21 interceptor and his evaluations allowed U.S. pilots to exploit the MiG’s weaknesses during the Vietnam War.

While testing General Dynamics F-111A 65-5701, Jordan and his co-pilot were forced to eject in the fighter’s escape capsule when the aircraft caught fire during a gunnery exercise at Edwards AFB, 2 January 1968. His back was injured in the ejection.

After Jordan retired from the Air Force in 1972, he became an engineering test pilot for the Northrop Corporation’s YF-17 flight test program.

Lieutenant Colonel Joe Bailey Jordan died at Oceanside, California, 22 April 1990, at the age of 60 years. His ashes were spread at Edwards Air Force Base. Jordan Street on the air base is named in his honor.

The Lockheed F-104C Starfighter was a tactical strike variant of the F-104A interceptor. The F-104C shared the external dimensions of the F-104A, but weighed slightly less.

The F-104C was powered by a single General Electric J79-GE-7 engine, a single-spool axial-flow afterburning turbojet, which used a 17-stage compressor and 3-stage turbine. The J79-GE-7 is rated at 10,000 pounds of thrust (44.482 kilonewtons), and 15,800 pounds (70.282 kilonewtons) with afterburner. The engine is 17 feet, 4 inches (5.283 meters) long, 3 feet, 2.3 inches (0.973 meters) in diameter, and weighs 3,575 pounds (1,622 kilograms).

The F-104C could carry a 2,000 pound weapon on a centerline hardpoint. It could carry up to four AIM-9B Sidewinder missiles.

On 9 May 1961, near Moron AFB, Spain, Starfighter 56-885 had a flight control failure with stick moving full aft. The pilot was unable to move it forward, resulting in an initial zoom climb followed by unrecoverable tumble. The pilot safely ejected but the airplane crashed and was destroyed.
