Navajo Skychief (serial number 2024), a Lockheed Model L-049-46 Constellation, had been built at Lockheed Aircraft Corporation’s Burbank, California, plant and delivered to Transcontinental and Western on 20 December 1945. The airliner remained in service with TWA until March 1962. During that time it was also named Star of the Nile and Star of California. The Constellation was scrapped in May 1964.
The Lockheed Constellation first flew in 1942, and was produced for the U.S. Army Air Corps as the C-69. With the end of World War II, commercial airlines needed new airliners for the post-war boom. The Constellation had transoceanic range and a pressurized cabin for passenger comfort.

The L-049 was powered by four air-cooled, supercharged and fuel-injected, 3,347.662-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division Cyclone 18 ¹ 745C18BA3 two-row 18-cylinder radial engines with a compression ratio of 6.5:1. The -BA3 was rated at 2,000 horsepower at 2,400 r.p.m., or 2,200 horsepower at 2,800 r.p.m., for takeoff, (five minute limit). The engines drove 15 foot, 2 inch (4.623 meter) diameter, three-bladed Hamilton Standard Hydromatic constant-speed propellers through a 0.4375:1 gear reduction. The 745C18BA3 was 6 feet, 4.13 inches (1.934 meters) long, 4 feet, 7.78 inches (1.417 meters) in diameter and weighed 2,842 pounds (1,289.11 kilograms).
The L-049 had a cruise speed of 313 miles per hour (503.72 kilometers per hour) and a range of 3,995 miles (6,429.3 kilometers). Its service ceiling was 25,300 feet (7,711 meters).
22 C-69s and 856 Constellations of all types were built. Designed by the famous Kelly Johnson, the Lockheed Constellation was in production from 1943–1958 in both civilian airliner and military transport versions. It is the classic propeller-driven transcontinental and transoceanic airliner.

1 February 1975: Major Roger J. Smith, United States Air Force, a test pilot assigned to the F-15 Joint Test Force at Edwards AFB, California, flew the McDonnell Douglas F-15A-6-MC 72-0119, Streak Eagle, to its eighth Fédération Aéronautique Internationale (FAI) and U.S. National Aeronautic Association time-to-altitude record.
From brake release at Grand Forks Air Force Base, North Dakota, at 913 feet (278 meters) above Sea Level, the F-15 reached 30,000 meters (98,425 feet) in 3 minutes, 27.799 seconds.
This was the eighth time-to-altitude record set by Streak Eagle in 17 days.

Streak Eagle, the modified McDonnell Douglas F-15A-6-MC, 72-0119, on the runway at Grand Forks AFB, North Dakota, being prepared for a flight record attempt. (U.S. Air Force)
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.
When 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.

Mrs. Macready with her husband, Lieutenant John Arthur Macready, shortly before his altitude record flight, 29 January 1926. (George Rinhart via Daedalians)
29 January 1926: At McCook Field, near Dayton, Ohio, First Lieutenant John Arthur Macready, Air Service, United States Army, took off in an experimental airplane, the Engineering Division XCO-5. Macready was attempting to exceed the existing Fédération Aéronautique Internationale world altitude record of 12,066 meters (39,587 feet), which had been set by Jean Callizo at Villacoublay, France, 21 October 1924.¹
The official observers of the National Aeronautic Association were Orville Wright (co-inventor with his brother Wilbur, of the airplane); George B. Smith of Dayton; and Levitt Luzurne Custer (inventor of the statoscope, the original barometric altimeter).
The Dayton Daily News reported:
Every part of the plane functioned perfectly. . . with the exception of the supercharging apparatus. The plane climbed to 25,000 feet in less than 45 minutes. The remainder of the flight was a fight against the dropping pressure in the motor.
In taking off, the altitude plane required approximately 50 feet and immediately began a steep ascent. Throughout the test the several hundred people who had congregated to see the flight start could find the plane by a long line of white vapor, which trailed in the wake of the ship in the rare atmosphere.
On other tests the plane has shown sea level pressure at approximately 32,000 feet. The super-charger showed a steadily declining pressure after 25,000 feet, indicating its lack of sufficient capacity for the motor. . .

Lieutenant John A. Macready, 28 September 1921. “The cold, though a severe drain on the system with the best protection possible, is more easily met. To prepare for it, Lieutenant Macready wears over his uniform, a heavy suit of woollen underwear and over that a thick heavily padded, leather-covered suit of down and feathers. Then, fur-lined gloves, fleece-lined moccasins over the boots, and a leather head mask lined with fur, which, with the oxygen mask, completely covers the face, completes the costume. The goggles are coated on the inside with anti-freezing gelatine supposed to function to 60 degrees below zero, Fahrenheit.” (NASM)
Lieutenant Macready reported, “My watch stopped at 30,000 feet and I believe it was frozen, because just before landing it started again.” He observed a temperature of -62 °C. (-79.6 °F.) at 34,600 feet (10,546 meters), which he said then increased to -56 °C. (-68.8 °F.) at 36,000 feet (10,973 meters).
When the airplane was inspected after landing at McCook Field, it was found that a crack had developed in the supercharger intercooler, allowing the supercharged air to escape. This resulted in a significant loss of power, and prevented Macready from passing Callizo’s record.
Lieutenant Macready reported that the Fédération Aéronautique Internationale altimeter (one of two altimeters in the airplane’s cockpit) had indicated that he had reached a maximum of 36,200 feet (11,034 meters). When the sealed barograph was sent to the Bureau of Standards in Washington, D.C., for calibration, it indicated a peak altitude of 38,704 feet (11,797 meters). This was 269 meters (883 feet) lower than the existing world record, but it did establish a new United States national altitude record.
Letter from Orville Wright to the National Aeronautic Association, 11 March 1926.Engineering Division XCO-5, A.S. 23-1204. (U.S. Air Force)
The XCO-5 was a prototype two-place, single-engine, two-bay biplane, a reconnaissance and observation variant of the TP-1 fighter. It was built by the Engineering Division at McCook Field. The airplane carried project number P305 painted on its rudder.
The XCO-5’s wings were built specifically for flight at very high altitude, using an airfoil (Joukowsky StAe-27A) designed by Professor Nikolay Yegorovich Zhukovsky (Николай Егорович Жуковский), head of the Central AeroHydroDynamics Institute (TsAGI) at Kachino, Russia. The two-bay biplane wings had a significant vertical gap and longitudinal stagger. The lifting surface was 600 square feet (55.742 square meters). The upper wing had dihedral while the lower wing did not.
The XCO-5 was 25 feet, 1 inch long (7.645 meters) with a wingspan of 36 feet (10.973 meters) and height of 10 feet (3.048 meters). The empty weight was 2,748 pounds (1,246 kilograms) and the gross weight was 4,363 pounds (1,979 kilograms).
The XCO-5 was powered by a water-cooled, 1,649.34-cubic-inch-displacement (27.028 liter) Liberty 12 single overhead cam (SOHC) 45° V-12 engine. It produced 408 horsepower at 1,800 r.p.m. The L-12 is a right-hand tractor, direct-drive engine. As installed on A.S. 23-1204, the engine turned a specially-designed, two-bladed, ground-adjustable, forged aluminum propeller with a diameter of 10 feet, 6 inches (3.200 meters). The Liberty 12 was 67.375 inches (1.711 meters) long, 27.0 inches (0.686 meters) wide, and 41.5 inches (1.054 meters) high. It weighed 844 pounds (383 kilograms).
Also installed on A.S. 23-1204 was an experimental supercharger. FLIGHT explained:
Since the Liberty engine, which delivers 400 h.p. at sea level, has an output of but 50 h.p. at 35,000 feet unsupercharged, a supercharger is a prime requisite of altitude work. The General Electric Form F, 20,000-ft. side type supercharger used in previous tests, with certain modifications, has been installed. The supercharger is an air compressor which keeps the air pressure in the carburettor at sea level pressure at heights where, owing to the natural decrease in the air pressure, the horsepower gradually falls away but to a fraction of its original output. In former supercharger installations, much difficulty was experienced with pre-ignition of the engine. This often became so pronounced that the plane had to be brought to earth. It was suspected that a richer mixture with the supercharger at altitude was necessary. This was found to be true but the principal difficulty was the overheating of the mixture due to the heat generated in the supercharger itself. Due to the increase in temperature created by the compression in the supercharger, it was necessary to interpose an intercooler between the supercharger outlet and the carburettor in order to obtain satisfactory engine performance. The intercooler, in the form of a honeycomb radiator, was placed on the side of the aeroplane. It was also found that the poor conductivity of the air at high altitudes, additional radiating surface for engine cooling was required. This, with the correction of mixture, put an end to pre-ignition.

Mrs. Thaden Flies Akron-Detroit Route In 40 Minutes; Beats Ray Brown Record
Time Officially Clocked as Plane Hurtles Over Municipal Airport
By Helen Waterhouse
RUSHING through space in her streamlined blue plane yesterday afternoon, Mrs. Louise Thaden, plucky Bendix race winner, broke all previous records between Detroit and Akron.
The tall Arkansas girl crossed Akron airport just 40 minutes and 43 seconds after leaving Detroit. That constituted an official record, Ray Brown, official of the National Aeronautic association, said.
“Wheels off and over the line, is the timing rule,” said Brown. “While Mrs Thaden did not actually land on the port until almost three minutes later, the time crossing the port is what counts.”
The ship had accumulated such speed that it far overshot the port, and came roaring back from the east with the thunder of an army bomber.
BEATS BROWN BY TWO MINUTES
“I beat you by two minutes, Ray,” called the smiling aviatrix as she leaned from the cockpit.
She was referring to an unofficial record made by Brown last November. At that time Brown made the trip in 42 minutes, but there were no official checkers to record it.
J.A. McCann and Airport Manager B.E. “Shorty” Fulton served in this capacity with Brown yesterday.
The girl who has constantly made air records then climbed nimbly from the ship to be greeted by her hostess, Mrs. Brown, and a small crowd of spectators.
Aside from the fact that her eyes were bloodshot from the wind, she showed no effects of the terrific speed at which she had traveled. “I hardly knew I had been in the air, it was such a short trip,” she laughed.
Bareheaded when she landed, she jammed a gray sports hat onto her tousled hair as she alighted. She wore a gray flannel dress, gray sports shoes and a belted caracul coat.
BLAMES SELF FOR PASSING PORT
Lighting one cigaret after another, she upbraided herself for having so far overshot the port.
“Gosh, I don’t know what my top speed was,” she said. “I was too busy up there. I flew at 5,000 feet all the way.”
She scanned the lowering clouds. A few drops of rain were falling. “Doubt if I get off for Montreal tomorrow,” she said cheerfully.
She explained that from Montreal she is flying to the air show in New York City.
Brown figured that the girl had averaged 160 miles and hour over the 110-mile route.
“I just thought it would it would be fun to try to beat your record,” Mrs. Thaden said to him.
After watching her speedy little ship into the Akron Airways hangar, she rode to town with the Browns.
“Things are definitely picking up in the air industry,” she said. “In the last few months I have flown all over the country, and I see great evidence of the pickup in the industry all along the line.
—Akron Beacon Journal, Vol. 98, No. 41, Friday, 22 January 1937, Page 21, at Column 5–7.
[The distance between Detroit Metropolitan Airport (DTW) and Akron Fulton International Airport (AKR) is 127 statute miles (204 kilometers). Mrs. Thaden’s average speed over the course would have been 187.147 miles per hour (301.184 kilometers per hour).]
Just four months, 18 days earlier, Louise Thaden had become the first woman to win the Bendix Trophy Race, flying another Beechraft C17R “Staggerwing,” R15835, serial number C17R-77, from Floyd Bennett Field, Brooklyn, New York, to Mines Field, Los Angeles, California, in 14 hours, 55 minutes, 1.0 seconds.¹ [At this time, airplanes in the experimental or restricted categories were prohibited from displaying the U.S. national identifier, the letter N, as they were not allowed to fly outside the United States.]

The Bendix race winning airplane had already been sold to the government of the República de Honduras, but Walter Beech let Louse Thaden and Blanche Wilcox Noyes fly it for the race. It was then returned to the Beechcraft plant for overhaul and repainting, before being flown to Honduras by Paul E. Zimmerman. It was assigned to the Escuela Militar de Aviacion.
Beech had another Beechcraft C17R, serial number C17R-81, and also registered NC15835, built for Louise Thaden in October 1936, the month after the Bendix Trophy Race. After being test flown by Mrs. Thaden, it was delivered to her 12 October 1936. It was painted Consolidated Blue with white trim in the same paint scheme as C17R-77. The interior had blue leather seats with Colonial Blue carpet.
C17R-81 is the airplane that Thaden flew to set the 21 January 1937 record.
The Beechcraft C17R was single-engine, single-bay biplane operated by a single pilot and could carry up to three passengers in its enclosed cabin. The basic structure was a welded tubular steel frame with wood formers and stringers. The wings and tail surfaces were built of wood spars and ribs with the leading edges and wing tips covered with plywood. The airplane was covered with doped fabric, except the cabin and engine, which were covered in sheet metal. It was equipped with electrically-operated retractable landing gear and wing flaps.
The Beechcraft Staggerwing got its name because its lower wing was placed ahead of the upper wing (negative stagger). While most biplanes had staggered wings, the Staggerwing was unusual in having negative stagger. This not only increased the pilot’s field of vision, but improved the airplane’s stability in a stall. The Staggerwing was a fast airplane for its time and set several speed and altitude records.
The Beech C17R was 24 feet, 5 inches (7.442 meters) long with a wingspan of 32 feet, 0 inches (9.754 meters) and overall height of 8 feet, 2 inches (2.489 meters). According to the Bureau of Air Commerce license certificate dated 9 October 1936, C17R-81 had an empty weight of 2,393 pounds (1,085 kilograms), and its maximum gross weight was 3,900 pounds (1,769 kilograms).
The leading edge of the Model C17 upper wing was 2 feet, 1 inches (0.635 meters) aft of the lower wing. The leading edges had 0° sweep. Both wings had an angle of incidence of 3°. The upper wing had no dihedral, but the lower wing had +1°. The mean vertical gap between the wings was 5 feet (1.524 meters), and the chord of both wings was 5 feet, 0 inches (1.524 meters). The total wing area was 273 square feet (25.4 square meters). The horizontal stabilizer had 0° incidence, while the vertical fin was offset 0° 43′ to the left of the airplane’s centerline.

The Staggerwing was offered with a selection of engines of different displacements and horsepower ratings. The C17R was powered by an air-cooled, supercharged, 971.930-cubic-inch-displacement (15.927 liter) Wright Whirlwind 440 (R-975E3), a 9-cylinder direct-drive radial engine with a compression ratio of 6.3:1. The R-975E3 was rated at 420 horsepower at 2,200 r.p.m., and 440 horsepower at 2,250 r.p.m. for takeoff, burning 92-octane gasoline. The engine was 43.00 inches (1.092 meters) long and 45.25 inches (1.149 meters) in diameter. It weighed 700 pounds (318 kilograms). The serial number of the engine installed in C17R-81 was 12885. It drove a two-bladed adjustable pitch Hamilton Standard propeller with a diameter of 8 feet, 6 inches (2.591 meters), serial number 18560.
This engine gave the C17R Staggerwing a cruise speed of 195 miles per hour (314 kilometers per hour) at 5,000 feet (1,524 meters), 202 miles per hour (325 kilometers per hour) at 10,000 feet (3,048 meters) and maximum speed of 211 miles per hour (340 kilometers per hour). The service ceiling was 21,500 feet (6,553 meters) and its range with standard fuel capacity, 98 gallons (371 liters), was 800 miles (1,288 kilometers).
The rear passenger seats of C17R-81 were removed and a 56 gallon (212 liter) auxiliary fuel tank installed in their place, bringing to total fuel capacity to 121 gallons (458 liters).
Three C17R Staggerwings have been registered as N15835, including serial numbers C17R-74; C-17R-77, the Bendix race winner; and C17R-81, which was built for Thaden. FAA records indicate that the first, C17R-74, is currengtly registered N15835.
Mrs. Thaden’s personal C17R, s/n C17R-81, an incomplete restoration, was for sale at auction in November 2023.

Roger Smith’s United States National Record still stands.
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 operational, 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 M61 cannon and its ammunition handling equipment, the radar and fire control systems, unneeded cockpit displays and radios, and one generator.
Other equipment was added: An extended 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-back 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.

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, and for the 20,000 meter climb, weighed 29,877 pounds (13,552 kilograms). 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.
When the F-15 reached 428 knots (793.4 kilometers per hour), the pilot pulled up into an Immelman, holding 2.5 Gs. Streak Eagle arrived back over the air base, in level flight at about 32,000 feet (9,754 meters), but upside down. Rolling up right, Streak Eagle continued accelerating to Mach 1.5 when the pilot pulled the fighter up at 4.0 Gs until it reached a 55° climb angle until it reached 20,000 meters
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. It was transferred to the National Museum of the United States Air Force at Wright-Patterson Air Force Base, Ohio, in December 1980.
