The Northrop T-38A Talon is a two-place, twin-engine jet trainer capable of supersonic speed. It is 46 feet, 4 inches (14.122 meters) long with a wingspan of 25 feet, 3 inches (7.696 meters) and overall height of 12 feet, 10 inches (3.912 meters). The trainer’s empty weight is 7,200 pounds (3,266 kilograms) and the maximum takeoff weight is 12,093 pounds (5,485 kilograms).

The T-38A is powered by two General Electric J85-GE-5 turbojet engines. The J85 is a single-shaft axial-flow turbojet engine with an 8-stage compressor section and 2-stage turbine. The J85-GE-5 is rated at 2,680 pounds of thrust (11.921 kilonewtons), and 3,850 pounds (17.126 kilonewtons) with afterburner. It is 108.1 inches (2.746 meters) long, 22.0 inches (0.559 meters) in diameter and weighs 584 pounds (265 kilograms).

It has a maximum speed of Mach 1.08 (822 miles per hour, 1,323 kilometers per hour) at Sea Level. The Talon’s service ceiling of 55,000 feet (16,764 meters) and it has a maximum range of 1,093 miles (1,759 kilometers).

In production from 1961 to 1972, Northrop has produced nearly 1,200 T-38s. As of January 2014, the U.S. Air Force had 546 T-38A Talons in the active inventory. It also remains in service with the U.S. Navy, and the National Aeronautics and Space Administration.

Walter Fletcher Daniel was born in 1925. He entered the U.S. Army Air Corps in 1943 and was trained as a fighter pilot. He was assigned to fly North American P-51 Mustangs and Republic P-47 Thunderbolts in post-war Germany. During the Korean War he served as a reconnaissance pilot of RF-51s and RF-80 Shooting Stars.

Walter Daniel graduated from the U.S. Air Force Experimental Test Pilot School in 1954 and was assigned to Wright-Patterson Air Force Base and later Edwards Air Force Base, where he was involved in flight testing all of the Century-series fighters. (F-100–F-106) It was while at Edwards that he flew the T-38A to set the time-to-altitude records.

By 1965, Colonel Daniel was the Chief of Flight Test Operations for the Lockheed YF-12A and SR-71A Blackbird Mach 3 aircraft. He set five world speed records and an altitude record and was awarded the Mackay Trophy.

After attending the Air War College, Daniel entered combat crew training in the McDonnell F-4 and RF-4 Phantom II, and was appointed Deputy Commander for Operations of the 432d Tactical Reconnaissance Wing at Udorn RTAFB. He flew 70 combat missions over North Vietnam.

In 1971 Colonel Daniel assumed command of the 75th Tactical Reconnaissance Wing (soon redesignated 67th TRW). He was promoted to brigadier general in 1972 and served as Inspector General, Air Force Systems Command.

Walter Fletcher Daniel was a member of the Society of Experimental Test Pilots. A command pilot, he had flown over 6,000 hours in more than 75 different aircraft types. General Daniel died 13 September 1974 at the age of 49 years. He is buried at the Arlington National Cemetery.

14 January 1936: Flying a Northrop Gamma 2G, serial number 11, which he had leased from Jackie Cochran, Howard Robard Hughes, Jr., set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Recognized Course (Los Angeles, California, to New York) in 9 hours, 26 minutes, 10 seconds, at an average speed of 417.0 kilometers per hour (259.1 miles per hour).¹ Most of the flight was made at altitudes of  15,000–18,000 feet (4,572–5,486 meters), and Hughes used supplemental breathing oxygen.

Jack Northrop had designed and built the Gamma as a long-range cargo and mail plane for Transcontinental and Western Air, Inc. The contract was cancelled, though, and several airplanes became available to other customers. Jackie Cochran purchased s/n 11, which had been completed 15 August 1934, and had it modified by Northrop as a two-place long-distance racer for the 1934 MacRobertson London-to-Australia air race, which she planned to fly with her friend Ted Marshall.

The Gamma’s original engine was replaced with a liquid-cooled, supercharged, 1,570.381-cubic-inch-displacement (25.734 liters) Wright Aeronautical Division Conqueror SGV1570F4 (also known as the Curtiss Conqueror), a DOHC 60° V-12 engine rated at 745 horsepower at Sea Level. The engine drove a two-bladed propeller. The Gamma had 7 fuel tanks: 3 in each wing and 1 in the fuselage. Total capacity was 486 gallons (1,840 liters) of gasoline and 29 gallons (110 liters)of lubricating oil. A second fuselage tank was later added, bring the total fuel capacity to 586 gallons (2,218 liters). The Gamma 2G had an empty weight of 4,727 pounds (2,144 kilograms) and a maximum gross weight of 8,037 pounds (3,646 kilograms). The modified airplane was inspected and a temporary commercial registration, NC13671, was approved 29 September 1934.

While being ferried to New York by Jackie and her new copilot, Royal Leonard, problems with the engine’s supercharger forced them to land in Arizona. Cochran continued east by airliner while Leonard and a Curtiss-Wright mechanic continued east in the Gamma. Flying on the night of 1 October 1934, a continuing problem with the supercharger forced them to make an off-field landing near Tucumcari, New Mexico, using light from dropped flares. The Gamma was seriously damaged and had to be returned to Northrop for repair.

The airplane’s temporary registration was suspended. A section of the wing and the forward lower half of the fuselage were replaced, provisions for installing a Pratt & Whitney radial engine were made, and the rear cockpit was removed. (Cochran’s plans for the MacRobertson Race had to be revised,² so she had the airplane modified for the Bendix Trophy Race.) The repairs and modifications were completed 30 November 1934.

The “re-modified” Gamma 2G was now powered by an air-cooled, supercharged, 1,534.943-cubic-inch-displacement (25.153 liters) Pratt & Whitney Twin Wasp Jr. SA1-G 14-cylinder radial engine with a three-bladed Hamilton Standard controllable-pitch propeller. The SA1-G was rated at 700 horsepower at 2,500 r.p.m. at 6,500 feet (1,981 meters). It could be ordered with a 3:2 or 4:3 gear reduction ratio.

The official ownership history of the Gamma is murky. The original application for a Department of Commerce Aeronautics Branch license specified the owner as The Northrop Corporation. On 4 January 1935, Northrop’s registration was cancelled by the Department of Commerce because, “Aircraft not inspected for relicensing.”

Jackie Cochran flew the Gamma in the 1935 Bendix Trophy Race, but did not finish.

When Jackie Cochran requested registration in her name, she failed to submit a Bill of Sale with her application. After repeated written requests by the Bureau of Air Commerce to submit a bill of sale went unanswered, her application for a restricted registration for the airplane was cancelled, 9 January 1936. J Carroll Cone, Assistant Director of Air Commerce (Air Regulation) informed her in writing: “The status of this aircraft is unlicensed and unidentified, according to our records. Any operation thereof would be in violation of the Air Commerce Regulations and subject the offender to the civil penalty provided therefor.”

Finally, a Bill of Sale from The Northrop Corporation, dated 30 November 1935, was provided to the Aeronautics Bureau. It said that Northrop had sold the airplane to Cochran, “for and in consideration of ten dollars ($10.00)”.

Meanwhile, Howard Hughes had seen the Gamma and wanted to buy it. Jackie Cochran tells how Howard Hughes acquired the airplane:

One night about 11:30 I was exhausted in my hotel room and the telephone rang. . .

“Jackie,” the voice says, “this is Howard.”

“Howard who?” I say, still sleepy and getting frustrated.

“Howard Hughes,” the man says.

“Howard who?” I ask again.

“Howard Hughes,” he repeats.

. . . We argued about who he was a bit more. Finally, he says, “I want to buy your airplane.”

I’m thinking that this is an incredible conversation. “It’s not for sale, Howard,” I reply. “I’m going to fly it in the Bendix.”

“I don’t want to fly it in the Bendix,” he answers. “I want to fly it cross-continental.”

“So do I,” I say.

Howard Hughes and I negotiated over the Northrop Gamma for about four weeks. . . Howard wanted my Northrop so badly, but it would break my heart to consider handing over my rights to it. . . when he offered to rent it, with an option to buy, I caved in. . . .

Jackie Cochran: An Autobiography, by Jacqueline Cochran and Maryann Bucknum Brinley, Bantam Books, New York, 1987, at 152–153.

When Hughes took possession of the Gamma 2G, he had the Pratt & Whitney engine replaced with a 1,823.129 cubic-inch (29.785 liter) Wright Cyclone SGR-1820-G5 nine-cylinder radial engine, and a three bladed-Hamilton Standard constant-speed propeller with a diameter of 11 feet, 3 inches (3.429 meters). The engine had a Normal Power rating of 830 horsepower at 2,100 r.p.m to 4,300 feet (1,311 meters), and 930 horsepower for Takeoff. This engine did not yet have government certification. Three additional fuselage tanks were installed, increasing the Gamma’s fuel capacity to 690 gallons. Hughes did not submit the Gamma for Department of Commerce inspection and licensing. It was not approved in the new configuration.

Jackie Cochran took the Gamma back from Hughes and had the Twin Wasp Jr. reinstalled, and submitted a new application for registration 31 March 1936. This was approved 28 April 1936, and the Gamma received a restricted registration, NR13761. It was damaged beyond repair after an emergency landing, 10 July 1936.

21 October 1947: At Northrop Field, Hawthorne, California, Northrop Corporation Chief Test Pilot Max R. Stanley took off in the first YB-49, 42-102367, and flew it to Muroc Air Force Base (now, Edwards Air Force Base) for flight testing.

42-102367 had been converted from the second YB-35 pre-production test aircraft. The original Flying Wing’s four Pratt & Whitney Wasp Major (R-4360-21) radial engines were replaced by eight Allison J35-A-5 turbojet engines and several aerodynamic improvements were made.

The YB-49 was a very unusual configuration for an aircraft of that time. There was no fuselage or tail control surfaces. The crew compartment, engines, fuel, landing gear and armament was contained within the wing. Air intakes for the turbojet engines were placed in the leading edge of the wing. The exhaust nozzles were at the trailing edge. Four small vertical fins for improved yaw stability were also at the trailing edge.

The YB-49 had a length of 53 feet, 1 inch (16.180 meters), wingspan of 172 feet (52.426 meters) and overall height of 15 feet, 2 inches (4.623 meters). It weighed 88,442 pounds (40,117 kilograms) empty and the gross weight was 193,938 pounds (87,969 kilograms).

The YB-49 was powered by eight General Electric-designed, Allison Engine Company-built J35-A-5 engines. The J35 was a single-spool, axial-flow turbojet engine with an 11-stage compressor and single-stage turbine. The J35-A-5 was rated at 4,000 pounds of thrust (17.79 kilonewtons) at 7,700 r.p.m. (static thrust, Sea Level). The engine was 14 feet, 0.0 inches (4.267 meters) long, 3 feet, 4.0 inches (1.016 meters) in diameter and weighed 2,400 pounds (1,089 kilograms). (This same engine variant was used in the North American Aviation XP-86, replacing its original Chevrolet-built J35-C-3.)

During testing the YB-49 reached a maximum speed of 493 miles per hour (793 kilometers per hour) at 20,800 feet (6,340 meters). Cruise speed was 429 miles per hour (690 kilometers per hour). The airplane had a service ceiling of 45,700 feet (13,929 meters). Maximum range was 3,575 miles (5,753 kilometers).

Only two Northrop YB-49s were built and they were tested by Northrop and the Air Force for nearly two years, and though an additional nine YB-35s were ordered converted, the B-49 was not placed into production.

The second ship, YB-49 42-102368, disintegrated in flight during a test flight north of Muroc Air Force Base, 5 June 1948, killing the entire crew, which included Captain Glen Edwards. The name of Muroc was changed to Edwards Air Force Base in his honor.

YB-49 42-102367 was destroyed by fire following a taxiing accident at Edwards, 15 March 1950. The program was cancelled on the same day.

12 October 1961: From August to October 1961, Jackie Cochran, a consultant to Northrop Corporation, set a series of speed, distance and altitude records while flying a Northrop T-38A-30-NO Talon supersonic trainer, serial number 60-0551. On the final day of the record series, she set two Fédération Aéronautique Internationale (FAI) world records, taking the T-38 to altitudes of 55,252.6 feet (16,841 meters) in horizontal flight ¹ and reaching a peak altitude of 56,072.8 feet (17,091 meters). ²

Famed U.S. Air Force test pilot Chuck Yeager, a close friend of Jackie Cochran, kept notes during the record series:

“October 12  Jackie took off at 9 am in the T-38 using afterburner. Bud Anderson and I chased her in the F-100. It was an excellent flight with everything working perfect. Jackie entered the course at 55,800 feet at .93 Mach and accelerated to radar. At the end of the run Jackie pulled up to 56,800 and then pushed over. She cut the right afterburner at 52,000 feet and the left one at 50,000. At 12,000 feet she removed the face piece from her pressure suit and made a perfect landing on the lake bed.

“Northrop-Air (Norair) presented Miss Cochran with one dozen yellow roses.

“A very tender ending to a wonderful program and a fitting token to a wonderful lady—a pilot who gave Norair much more than they expected.”

— Brigadier General Charles Elwood (“Chuck”) Yeager, U.S. Air Force, quoted in Jackie Cochran: An Autobiography, by Jacqueline Cochran and Maryann Bucknum Brinley, Bantam Books, New York, 1987, Pages 307–308.

The T-38A is a two-seat, twin-engine jet trainer capable of supersonic speed. It is powered by two General Electric J85-5A turbojet engines producing 2,050 pounds of thrust (3,850 with afterburner). Jackie Cochran demonstrated its maximum speed, Mach 1.3. It has a service ceiling of 50,000 feet (15,240 meters) and a range of 1,140 miles (1,835 kilometers). In production from 1961 to 1972, Northrop has produced nearly 1,200 T-38s. It remains in service with the U.S. Air Force, U.S. Navy, and the National Aeronautics and Space Administration.

Jackie Cochran’s record-setting T-38 is in the collection of the Smithsonian Institution, National Air and Space Museum.

6 October 1961: During a two-month series of speed, distance and altitude record attempts at Edwards Air Force Base, California, Jackie Cochran set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 100 Kilometers Without Payload, flying a Northrop T-38A-30-NO Talon, 60-0551. Her average speed over the 62-mile circular course was 1,262.188 kilometers per hour (784.287 miles per hour).¹

Jackie’s friend, famed Air Force test pilot Colonel Chuck Yeager, kept notes during the series of record attempts:

September 29: Edwards AFB. Flew the aircraft today to include a practice run on the 100 kilometer course. Jackie did a fine job at 1.2 Mach. Looks like this will be a piece of cake. Aircraft was okay. Average speed 742 miles per hour. Jackie was in the altitude chamber today with the pressure suit (CSU 4/P). Everything went fine and maximum altitude was 65,000 feet. This is the first time a woman was taken up in the chamber in a pressure suit. CSU 4/P was the type of suit.

October 3: Tried a run today but weather moved in from 26,000 to 37,000 feet. Very good landing. Airspeed system iced up and Jackie stalled the aircraft at 35,000 feet. Made a no-sweat recovery.

October 4: Ran the 100 kilometer for record at 1 pm. The first run wasn’t too good but had an average speed of 763 mph. A pylon was cut so the run was voided. Second run was 740 mph. Very poor. Another flight was made at 5:30 pm but both runs were pretty sorry. Jackie was a little late on all of the corrections. Jackie doesn’t seem to be in too good a physical or mental state.

October 5: I flew in the backseat of the T-38 with Jackie on a practice run of the 100 kilometer. I talked her around the course 2 times with a little help on the stick. First run was 782 mph and second run was 787. I think I know what has been Jackie’s trouble on the 100 km. During the flight as she starts gaining a little altitude, she lets off on the back pressure on the stick to stop climbing and this causes the turn to become larger. Jackie and I spent two hours talking this over. She finally understands that in order to fly a constant circle, if the airplane starts to climb, she must increase the bank angle and let off on the back pressure a little and let the nose drop but still hold the same rate of turn. This is what makes the 100 km so hard to fly. Jackie still has a touch of the flu.

October 6: Jackie felt better today and after a delay caused by communication trouble, she flew one of the most perfect runs that has ever been flown on the 100 km course. She learned her lesson well. The record speed was 784 mph. She held 1/4 mile outside the course the entire trip. I was very pleased to watch the reaction of the timers and radar people. I think they expected another 10 or 15 trips like the F-105 tricks. She made one hell of a good flight.
