10 February 1960: Delta Air Lines’ Superintendant of Flight Operations, Captain Thomas Prioleau Ball, Jr., made the delivery flight of Delta’s first Convair 880 jet airliner, Ship 902, named Delta Queen, FAA registration N8802E, from San Diego, California, to Miami, Florida. Other members of the flight crew were Captain James H. Longino, co-pilot, and First Officer Richard E. Tidwell, flight engineer.

Newspapers reported that Delta Queen‘s wheels started rolling on the runway at San Diego’s Lindbergh Field (SAN) at 10:11:46 a.m., Pacific Standard Time (18:11:46 UTC). The airplane took of and climbed to its cross-country cruising altitude of 33,000 feet (10,058 meters). The Convair 880 landed at Miami International Airport (MIA) at 4:42:08 p.m., Eastern Standard Time (21:42:08 UTC). The official flight time was 3 hours, 31 minutes, 54 seconds, for an average speed of 641.77 miles per hour (1,032.83 kilometers per hour) over the 2,266 mile (3,647 kilometers) route. This was a new United States National Record for Speed Over a Commercial Airline Route. The 880 cut 27 minutes, 1 second, off the time of an Eastern Air Lines Douglas DC-8B over the same route, 4 January 1960.

The Convair 880 was a four-engine, swept-wing turbojet-powered commercial airliner. It was operated by a flight crew of three and could carry up to 110 passengers. The Convair 880-22-M was a modified version of the standard 880-22, intended for shorter range operations. It had leading-edge slats, a higher maximum takeoff weight, stronger landing gear, a tail skid and an improved anti-lock braking system. The Convair 880 was so-named because its design top speed was 880 feet per second (600 miles per hour, or 966 kilometers per hour), faster than its Boeing 707 or Douglas DC-8 rivals.

The airplane was 129 feet, 4 inches (39.421 meters) long with a wingspan of 120 feet (36.576 meters) and overall height of 36 feet, 3.75 inches (11.068 meters). The 880 had an empty weight of 94,000 pounds (42,638 kilograms) and maximum takeoff weight was 191,000 pounds (86,636 kilograms).

The Convair 880-22-M was powered by four General Electric CJ805-3B turbojet engines. The CJ805-3B is a single-shaft, axial-flow turbojet with a 17-stage compressor section and 3-stage turbine, based on the military J79. The engine has a maximum continuous power rating of 9,800 pounds of thrust (43.593 kilonewtons) at Sea Level, and 11,650 pounds (51.822 kilonewtons) for Takeoff. The CJ805-3B is 9 feet, 2.4 inches (2.804 meters) long, 3 feet, 3.9 inches (1.013 meters) wide and 4 feet, 0.8 inches (1.240 meters) high. It weighs 2,875 pounds (1,304 kilograms).

The 880-22-M had a cruise speed of 0.82 Mach (556 miles per hour/895 kilometers per hour) at 30,000 feet (9,144 meters). The service ceiling was 41,000 feet (12,497 meters). Maximum range was 5,056 miles (8,137 kilometers).

The Convair Division of General Dynamics built 65 Convair 880 airliners at San Diego, California, between 1959 and 1962. Delta Air Lines retired its last one in January 1974.

Captain Thomas P. Ball

Thomas Prioleau (“Pre”) Ball, Jr., was a legendary airline captain. He was born 6 September 1906 at Norfolk, Virginia, the second son of Thomas Prioleau Ball, a bookkeeper, and Agnes Mae Bell Ball. He grew up in Florida. Ball learned to fly in 1928, soloing in a World War I Curtiss “Jenny” biplane.

Thomas P. Ball, Jr., married Miss Theresa Augusta Daniel at the Church of the Good Shepherd in Jacksonville, Florida, 27 December 1930. They would have to sons, Thomas Prioleaux Ball III and Espy Daniel Ball.

Ball worked as a station manager for Delta Air Lines at Charleston, South Carolina, and was hired as a copilot by the airline in 1936.

Soon after the United States entered World War II, Ball was commissioned as a second lieutenant in the U.S. Army Air Corps. By the end of the war, he had risen to the rank of colonel, serving as the Chief of the Prevention and Investigation Division of the Army’s Office of Flying Safety.

After the War, Ball returned to Delta Air Lines as a captain and soon became the chief pilot, dedicated to the meticulous training of the company’s pilots. In 1969, Ball became Delta’s Vice President of Flight Operations. On 25 May 1970, Ball was aboard Delta Flight 199, a Convair 880 under the command of Captain Harris B. Wynn, when it was hijacked to Cuba.

Four U.S. National Speed Records which were set by Captain Ball remain current. In addition to the record set with the Convair 880, on 6 November 1948, Ball flew a Delta Air Lines Douglas DC-6 from Los Angeles, California, to Charleston, South Carolina, in 6 hours, 24 minutes, 32 seconds, at an average speed of 344.19 miles per hour (553.92 kilometers per hour). On 18 March 1954, he flew a Douglas DC-7 from Los Angeles to Jacksonville, Florida, in 05:29:33, averaging 392.25 miles per hour (631.27 kilometers per hour). Finally, on 24 February 1962, Captain Ball flew a Douglas DC-8 from Miami, Florida, to Atlanta, Georgia, in 01:28:11, for an average of 406.1 miles per hour (653.56 kilometers per hour).

After making the delivery flight of the company’s first Boeing 747, Ball grounded himself when he noticed a deterioration in his eyesight. Thomas Prioleau Ball retired from Delta in 1971. He passed away in 2006 at the age of 99 years.

Convair 880-22-M N8802E, Delta Queen, (c/n 7) remained in service with Delta Air Lines until 1973 when it was sold to Boeing as part of exchange for an order of new Boeing 727-200 airliners. It was then sold to Transexecutive Aviation in 1974 and reregistered as N55NW. In 1976, the 880 flew as a charter airliner for Bahama World. It was then converted to a cargo freighter operating in the Caribbean. In 1979 the Convair was transferred to Groth Air Service, Inc., Castalia, Iowa, and assigned a new FAA registration, N880SR. The record-setting airliner was damaged beyond repair in a fire at Licenciado Benito Juarez International Airport, Mexico City, in May 1983.

21 January 1937: Iris Louise McPhetridge Thaden set a U.S. national record flying her Consolidated Blue Beechcraft C17R “Staggerwing,” NC15835 (serial number C17R-81) from Detroit, Michigan, to Akron Municipal Airport, Akron, Ohio, in 40 minutes, 43 seconds. She had departed Detroit, Michigan, at 3:07:17 p.m., Eastern Standard Time (20:07:17 UTC) and crossed overhead Akron at 3:38:00. (20:38:00 UTC).

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.

Iris Louise McPhetridge was born 12 November 1905 at Bentonville, Arkansas. She was the first of three daughters of Roy Fry McPhetridge, owner of a foundry, and Edna Hobbs McPhetridge. She was educated at the University of Arkansas at Fayetteville, a member of the Class of 1927. She majored in journalism, and played basketball. She was president of the Delta Delta Delta (ΔΔΔ) Sorority, Delta Iota (ΔΙ) Chapter, and president of The Panhellenic.

Louise McPhetridge had been employed by Walter Beech as a sales representative at Wichita, Kansas, and he included flying lessons with her employment. She received her pilot’s license from the National Aeronautic Association, signed by Orville Wright, 16 May 1928.

Miss McPhetridge married Mr. Herbert von Thaden at San Francisco, California, 21 July 1928. Thaden was a former military pilot and an engineer. They would have two children, William and Patricia. Thaden had founded the Thaden Metal Aircraft Company, builder of the all-metal Thaden T-1, T-2, and T-4 Argonaut. Thaden went on to design molded plywood furniture for the Thaden-Jordan Furniture Corporation. His designs are considered to be works of art, and individual pieces sell for as much as $30,000 today.

In 1929, she was issued Transport Pilot License number 1943 by the Department of Commerce. Mrs. Thaden was the fourth woman to receive an Airline Transport Pilot rating.

Louise Thaden is credited with having set four Fédération Aéronautique Internationale (FAI) world records.

Mrs. Thaden set an FAI World Record for Altitude of 6,178 meters (20,269 feet) over Oakland, California, 7 December 1928.²

On 17 March 1929, she set an FAI record for duration of 22 hours, 3 minutes, 28 seconds.³

14–22 August 1932 Thaden and Frances Marsalis flew a Curtiss Thrush to set an FAI world record for duation of 196 hours, 5 minutes.⁴

12 July 1936: World Record for Speed Over 100 Kilometers with an average speed of 176.35 kilometers per hour (109.58 miles per hour).⁵

Louise Thaden was secretary of the National Aeronautic Association, and was a co-founder of The Ninety-Nines, serving as that organization’s vice president and treasurer. She set several world and national records and was awarded the US. national Harmon Trophy as Champion Aviatrix of the United States in 1936. She was also employed by the Bureau of Air Commerce.

Louise Thaden stopped flying in 1938. She died at High Point, North Carolina, 9 November 1979.

7 January 1980: In response to a challenge, Alan W. Gerharter, Chief Flight Instructor of Logan and Reavis Air, Inc., Medford, Oregon, flew a four-place, single-engine Mooney M20K, N231LR, serial number 25-0025, from San Francisco International Airport (SFO) to Washington National Airport (DCA) in 8 hours, 4 minutes, 25 seconds.

This qualified as a new Fédération Aéronautique Internationale (FAI) and U.S. National Speed Record of 486.20 kilometers per hour (302.11 miles per hour).¹

Gerharter had beaten the previous record held by a Malvern Gross, Jr., ² flying a Cessna T210, N5119V, by 3 hours, 3 minutes, 23 seconds. When Gerharter arrived at DCA, Gross was there to meet him.

Gerharter had made temporary modifications to the Mooney for this flight. He had two 25 gallon (94.6 liter) fuel tanks mounted in place of the rear seats, bringing the airplane’s total fuel capacity to 122 gallons (462 liters). The right front seat was removed and two oxygen tanks installed. In an effort to reduce aerodynamic drag, he removed the boarding step at the trailing edge of the right wing.

Waiting for advantageous weather, Alan Gerharter took off from SFO at 6:49 a.m., Pacific Standard Time, 7 January 1980. He climbed to 25,000 feet (7,620 meters) and adjusted his power settings to 75%. Though he had meticulously planned a Great Circle Route, electrical problems caused his primary navigation system and autopilot to fail, so he had to navigate by magnetic compass and clock as he made his way across the country. The airplane used 103 gallons (390 liters) of fuel during the flight.Screen Shot 2015-01-06 at 08.56.45Alan Gerharter’s World and National Records still stand.

The Mooney M20K is an all-metal, low-wing monoplane with retractable tricycle landing gear. The airplane is 25 feet, 5 inches (7.747 meters) long with a wingspan of 36 feet, 1 inch (10.998 meters) and overall height of 8 feet, 3 inches (2.516 meters). Its empty weight is 1,800 pounds (816.5 kilograms) and gross weight is 2,900 pounds (1,315 kilograms).

The M20K is powered by an air-cooled, fuel-injected and turbocharged, 359.656-cubic-inch-displacement (5.894 liter) Teledyne Continental TSIO-360-GB-1 horizontally-opposed six-cylinder direct-drive engine. It has a compression ration of 7.5:1 and is rated at 210 horsepower at 2,700 r.p.m. with 40.0 inches manifold pressure (1.365 Bar). The engine turns a two-bladed McCauley constant-speed propeller with a diameter of 6 feet, 2 inches (1.879 meters). Most TSIO-360-GB engines still in service have been converted to the TSIO-360-LB configuration. The -LB is 2 feet, 3.53 inches (0.699 meters) high, 2 feet, 7.38 inches (0.797 meters) wide and 4 feet, 8.97 inches (1.447 meters) long. It has a dry weight of 343.35 pounds (155.74 kilograms).

The Mooney M20K was marketed as the Mooney 231, a reference to its top speed of 201 knots at 16,000 feet (4,877 meters), or 231.3 miles per hour (372.25 kilometers per hour). The M20K has a Maximum Structural Cruising Speed (VNO) of 200 miles per hour (321.9 kilometers per hour), and a Never Exceed Speed (VNE) of 225 miles per hour (362.1 kilometers per hour). The airplane has a maximum operating altitude of 24,000 feet (7,315 meters).

The M20K was certified in 1979, 24 years after the original M20 entered production, and it was produced until 1998. The M20 series continued in production with follow-on models until 2008.

29 December 1949: Jackie Cochran (Lieutenant Colonel, United States Air Force Reserve) flew her North American Aviation P-51C Mustang, Thunderbird, CAA registration N5528N, to two Fédération Aéronautique Internationale (FAI) Class C-1 world speed records of 703.38 kilometers per hour (437.06 miles per hour)¹ and a U.S. National record of 703.275 kilometers per hour (436.995 miles per hour) over the 500 kilometer (310.7 mile) Desert Center–Mt. Wilson course in the Colorado Desert of southern California.

She would later be awarded the first of three Distinguished Flying Crosses for this series of flight records.

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 just ten days earlier, 19 December 1949.

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

Thunderbird had won the 1949 Bendix Trophy Race with pilot Joe De Bona, after he had dropped out of the 1948 race. Its engine had been upgraded from a Packard V-1650-3 Merlin to a V-1650-7 for the 1949 race.

Jackie Cochran set three world speed records with Thunderbird. In 1953, she sold it back to Jimmy Stewart. After changing ownership twice more, the P-51 crashed near Scott’s Bluff, Nebraska, 22 June 1955 and was totally destroyed. Pilot James M. Cook parachuted with minor injuries.

The P-51B and P-51C Mustangs are virtually identical. The P-51Bs were built by North American Aviation, Inc., at Inglewood, California, while 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 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 and 60 inches of manifold pressure (V-1650-3) or 1,490 horsepower at Sea Level, turning at 3,000 r.p.m. with 61 inches of manifold pressure (V-1650-7). 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).

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 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.

According to the Smithsonian Institution National Air and Space Museum, “At the time of her death in 1980, Jacqueline Cochran held more speed, altitude, and distance records than any other male or female pilot in aviation history.”

Distinguished Flying Cross

For a series of six records set in her P-51, Jackie Cochran, who held a commission as a colonel in the United States Air Force, was awarded the Distinguished Flying Cross.

The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting the Distinguished Flying Cross to Colonel Jacqueline Cochran, United States Air Force, for extraordinary achievement while participating in aerial flight from 1947 to 1951. During this period, Colonel Cochran piloted an F-51 aircraft in which she established six world speed records. At Coachella Valley, California, flying a closed-circuit 100-kilometer course, Colonel Cochran established a new speed record of 469.549 miles per hour. In other flights from Thermal, Indio, and Palm Springs, CA, Colonel Cochran established world speed records for the 3-, 15-, 500-, 1000-, and 2000-kilometer courses. The professional competence, aerial skill, and devotion to duty displayed by Colonel Cochran reflect great credit upon herself and the United States Air Force.

NX28388 was the first of three P-51 Mustangs owned by Jackie Cochran. It was a North American Aviation P-51B-15-NA Mustang built at Inglewood, California in 1944. It was assigned NAA internal number 104-25789 and U.S. Army Air Corps serial number 43-24760.

Cochran bought it from North American Aviation, Inc., 6 August 1946. The airplane was registered to Jacqueline Cochran Cosmetics, Inc., 142 Miller Street, Newark, New Jersey, but was based at Jackie’s C-O Ranch at Indio, California. The Mustang was painted “Lucky Strike Green” and carried the number 13 on each side of the fuselage, on the upper surface of the left wing and lower surface of the right wing.

NX28388 was powered by Packard V-1650-7 Merlin V-12, serial number V332415.

Jackie Cochran flew NX28388 in the 1946 Bendix Trophy Race and finished second to Paul Mantz in his P-51C Mustang, Blaze of Noon. Cochran asked Bruce Gimbel to fly the Mustang for her in the 1947 Bendix. There was trouble with the propeller governor and he finished in fourth place. In May 1948, Jackie set two more speed records with NX28388. Jackie and her green Mustang finished in third place in the 1948 Bendix race. She asked another pilot, Lockheed test pilot Sampson Held, to ferry the fighter back to California from Cleveland, Ohio after the race, but,

“. . . my plane crashed, carrying my associate, Sam Held, with it to his death.” The Stars At Noon, by Jacqueline Cochran, Little, Brown and Company, Boston, 1954, Chapter IV at Page 79.

NX28388 had crashed six miles south of Sayre, Oklahoma, 8 September 1948, killing Sam Held. Two witnesses saw a wing come off of the Mustang, followed by an explosion.

The P-51B was the first production Mustang to be built with the famous Rolls-Royce Merlin engine, and was virtually identical to the P-51C variant. (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 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 and 60 inches of manifold pressure (V-1650-3) or 1,490 horsepower at Sea Level, turning at 3,000 r.p.m. with 61 inches of manifold pressure (V-1650-7). 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).

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).
