12 April 1963: At Edwards Air Force Base, California, Jacqueline (“Jackie”) Cochran, Colonel, U.S. Air Force Reserve, established a Fédération Aéronautique Internationale (FAI) World Speed Record when she flew a two-place Lockheed TF-104G Starfighter named Free World Defender, FAA registration N104L, named Free World Defender, over a 15/25 kilometer (9.32/15.53 miles) closed circuit at an average speed of 2,048.88 kilometers per hour (1,273.115 miles per hour).¹

Jackie Cochran wrote about flying the 15/25 kilometer straight course in her autobiography:

“Picture in your mind a rectangular tunnel, 300 feet high, a quarter of a mile wide, and extending 20 miles long through the air at an altitude of 35,000 feet. I had to fly through that tunnel at top speed without touching a side. There were no walls to see but radar and ground instruments let me know my mistakes immediately. Up there at 35,000 feet the temperature would be about 45 degrees below zero. Not pleasant but perfect for what I was doing. Inside the plane you are hot because of the friction of speeding through the air like that. The cockpit was air-conditioned, but when you descend, things happen so fast the plane’s air-cooling system can’t keep up with it. I was always hot and perspiring back on the ground.”

Jackie Cochran: An Autobiography, by Jacqueline Cochran and Maryann Bucknum Brinley, Bantam Books, New York 1987, Page 314.

N104L was retained by Lockheed for use as a customer demonstrator to various foreign governments. In 1965 Lockheed sold N104L to the Dutch Air Force, where it served as D-5702 until 1980. It next went to the Turkish Air Force, remaining in service until it was retired in 1989.

9 April 1951: Jackie Cochran set a Fédération Aéronautique Internationale (FAI) world record and National Aeronautic Association U.S. National Record on 9 April 1951, flying her North American Aviation P-51C Mustang, N5528N, to an average speed of 464.374 miles per hour (747.338 kilometers per hour) over a straight 16 kilometer (9.942 miles) high-altitude course at Indio, California.¹

Thunderbird was Jackie Cochran’s third P-51 Mustang. She had purchased it from Academy Award-winning actor and World War II B-24 wing commander James M. Stewart, 19 December 1949. It was painted cobalt blue with gold lettering and trim.

Thunderbird had also won the 1949 Bendix Trophy Race from Rosamond Dry Lake, California, to Cleveland Municipal Airport, Ohio, with pilot Joe De Bona in the cockpit.

According to Civil Aviation Administration records, N5528N had been “assembled from components of other aircraft of the same type.” It has no USAAC serial number or North American Aviation serial number. The CAA designated it as a P-51C and assigned 2925 as its serial number. It was certificated in the Experimental category and registered N5528N.

The North American Aviation P-51 Mustang is a single-place, single-engine long range fighter. It is a low-wing monoplane with retractable landing gear and is of all-metal construction. The fighter is powered by a liquid-cooled V-12 engine. It was originally produced for the United Kingdom’s Royal Air Force as the Mustang Mk.I. Two examples were provided to the U.S. Army Air Corps, designated XP-51. This resulted in orders for the P-51A and A-36 Apache dive bomber variant. These early Mustangs were powered by the Allison V-1750 engine driving a three-bladed propeller, which also powered the Lockheed P-38 Lightning and Curtiss P-40 Warhawk.

In 1942, soon after the first  production Mustang Mk.I arrived in England, Rolls-Royce began experimenting with a borrowed airplane, AM121, in which they installed the Supermarine Spitfire’s Merlin 61 engine. This resulted in an airplane of superior performance.

In the United States, the Packard Motor Car Company of Detroit, Michigan, had begun building Merlin engines under license from Rolls-Royce. These American engines were designated V-1650. North American modified two P-51s from the production line to install the Packard V-1650-3. These were designated XP-51B. Testing revealed that the new variant was so good that the Army Air Corps limited its order for P-51As to 310 airplanes and production was changed to the P-51B.

The P-51B and P-51C are virtually Identical. The P-51Bs were built by North American Aviation, Inc., at Inglewood, California. P-51Cs were built at North American’s Dallas, Texas plant. They were 32 feet, 2.97 inches (9.829 meters) long, with a wingspan of 37 feet, 0.31-inch (11.282 meters) and overall height of 13 feet, 8 inches (4.167 meters) high. The fighter had an empty weight of 6,985 pounds (3,168 kilograms) and a maximum gross weight of 11,800 pounds (5,352 kilograms).

P-51Bs and Cs were powered by a right-hand tractor, liquid-cooled, supercharged, 1,649-cubic-inch-displacement (27.04-liter) Packard V-1650-3 or -7 Merlin single overhead cam (SOHC) 60° V-12 engine which produced 1,380 horsepower at Sea Level, turning 3,000 r.p.m at 60 inches of manifold pressure (V-1650-3) or 1,490 horsepower at Sea Level, turning 3,000 r.p.m. at 61 inches of manifold pressure (V-1650-7). (Military Power rating, 15 minute limit.) These were license-built versions of the Rolls-Royce Merlin 63 and 66. The engine drove a four-bladed Hamilton Standard Hydromatic constant-speed propeller with a diameter of 11 feet, 2 inches (3.404 meters) through a 0.479:1 gear reduction.

The P-51B/C had a cruise speed of 362 miles per hour (583 kilometers per hour) and the maximum speed was 439 miles per hour (707 kilometers per hour) at 25,000 feet (7,620 meters). The service ceiling was 41,900 feet (12,771 meters). With internal fuel, the combat range was 755 miles (1,215 kilometers).

In military service, armament consisted of four air-cooled Browning AN-M2 .50-caliber machine guns, mounted two in each wing, with 350 rounds per gun for the inboard guns and 280 rounds per gun for the outboard.

1,988 P-51B Mustangs were built at North American’s Inglewood, California plant and another 1,750 P-51Cs were produced at Dallas, Texas. This was nearly 23% of the total P-51 production.

3 June 1953: Concluding a series of speed and altitude record, Jackie Cochran set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15/25 Kilometer Straight Course with an average speed of 1,067.68 kilometers per hour (663.426 miles per hour) while flying the Canadair CL-13 Sabre Mk.3 No. 19200 at Edwards Air Force Base, California.

Type of record: Speed over a straight 15/25 km course

Course/Location: Edwards AFB, CA (USA)
Claimant Jacqueline Cochran (USA)
Aeroplane: Canadair F-86 E “Sabre”
Engine: 1 Avro Canada Orenda

In the previous weeks, Jackie Cochran had flown the experimental Orenda-powered Sabre to world records over the 100 and 500 kilometer closed circuit and set an altitude record. During these flights, she became the first woman to “break the sound barrier” when the Sabre Mk. 3 exceeded Mach 1. On the morning of 3 June, Cochran had attempted to set a new world record over the 3 kilometer straight course, which was flown at an altitude of 200 feet (61 meters). After two runs she determined that the Sabre Mk.3 would not exceed the previous record, and she abandoned the attempt.

The plane was immediately refueled and the timing devices were shifted to the 15-kilometer course. That took about two hours and the roughness in the air was building up by the minute. A pass in each direction over the 15-kilometer course was needed for an average speed, as against four passes over the 3-kilometer course. I had fuel enough for four passes. The average of any two consecutive passes could be taken. The first pass from south to north was at a speed of 680 miles per hour. That result was relayed to me by air from my own Lodestar, which was parked on the lake bed near the judges’ equipment. The second pass from north to south, with the wind against me, was at a speed of 670 miles per hour. I determined to make a third pass, even though the plane had developed a bad left-wing down roll at high speed and was in consequence next to unmanageable over the level flight course and its approaches. On this third pass I decided to take a long dive at the conclusion of which I would level out before reaching the approach to the course. I did this but, on leveling out, the controls again “froze” on me with the plane determined to roll over to the left. I used both arms to pull on the controls and one knee as well for leverage but with no effect. Another second or two and the plane would have been over on its back and into the ground. I prevented this only by slowing it down. At the moment I pulled back on the power there was an automatic temporary compensation of the direction of the plane to the right of the course and, as a result, the timing camera did not catch me on that third pass. That ended the flight. I made a long turn for landing and “Chuck” Yeager, in his chase plane, closed in behind me. He instructed me to leave the throttle untouched as much as possible and to land on the lake bed. I wanted to put the plane down on the runway where the ground crew was waiting but “Chuck” insisted that I put it down on the lake bed where I could take a high-speed landing and a long roll. I took my oxygen mask off and smelled fuel in the cockpit. When the wheels touched ground and the roll had about stopped, “Chuck” told me to cut the throttle and switches and get out as quickly as possible because I had a bad fuel leak which he had seen from his plane. A stream of fuel about the size of one’s thumb was gushing out of the bottom of the main section of the left wing. . . .

The Sabre Mk.3 was a one-of a kind CL-13 Sabre (an F-86E Sabre produced by Canadair Ltd. at Montreal, Quebec, under license from North American Aviation, Inc.) built to test the prototype Avro Canada Orenda 3 turbojet engine. Modifications to the airframe were required to install the larger engine. The Orenda produced 6,000 pounds of thrust, a 15% improvement over the J47-GE-13 installed in the standard F-86E.

After the speed and altitude records, No. 19200 was sent to North American Aviation for evaluation. Today, it is on static display outdoors at Wetaskiwin Regional General Airport (CEX3), Alberta, Canada.

The Dassault MD.454 Mystère IV N was a prototype two-place single-engine interceptor, powered by a Rolls-Royce Avon RA 7R afterburning turbojet engine. It had a large air-search radar mounted over the intake and was armed with 52 rockets carried in a retractable tray in the belly, very similar to the North American Aviation F-86D Sabre. The fuselage had been lengthened over the single-seat Mystère IV to provide space for the second cockpit. It was 49 feet, 11 inches (14.92 meters) long with a wingspan of 37 feet, 6 inches (11.12 meters) and overall height of 15 feet, 1 inch (4.60 meters). The empty weight was 15,741 pounds (7,140 kilograms) and maximum takeoff weight was 22,572 pounds (10,320 kilograms).
