24 May 1948: Two days after setting two Fédération Aéronautique Internationale (FAI) World and U.S. National Aeronautic Association speed records with her P-51B Mustang, Jackie Cochran sets two more.

Flying her “Lucky Strike Green” North American Aviation P-51B-15-NA, serial number 43-24760, civil registration NX28388, Cochran flew an average of 693.780 kilometers per hour (431.094 miles per hour) over a 1,000 kilometer (621.371 miles) closed circuit, without payload, at Santa Rosa Summit, near Indio, California.¹

Jackie Cochran bought NX28388 from North American Aviation, Inc., 6 August 1946. Cochran also flew the green P-51B in the 1946 and 1948 Bendix Trophy Races, in which she placed 2nd and 3rd. Her Mustang was flown by Bruce Gimbel in the 1947 Bendix race, placing 4th.

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).

The P-51B was the first version of the North American Aviation fighter to be powered by the Merlin engine in place of the Allison V-1710. Rolls-Royce had selected the Packard Motor Car Company to build Merlin aircraft engines in the United States under license. NX28388 was powered by a Packard-built V-1650-7, serial number V332415, which was based on the Merlin 66. It was a right-hand tractor, liquid-cooled, supercharged 1,649-cubic-inch-displacement (27.04-liter), single overhead cam (SOHC) 60° V-12 engine, which produced 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.) 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 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.

Cochran’s AP-7A was a specially-built racer, modified from the original AP-7 with a new, thinner, wing and different landing gear arrangement. It was powered by a an air-cooled, supercharged, 1,829.39-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp S1B3-G (R-1830-11) two-row 14-cylinder radial engine rated at 850 horsepower at 2,450 r.p.m. at 5,000 feet (1,524 meters), and 1,000 horsepower at 2,600 r.p.m. for take off. The engine turned a three-bladed Hamilton-Standard controllable-pitch propeller through a 3:2 gear reduction. The R-1830-11 was 4 feet, 8.66 inches (1.439 meters) long with a diameter of 4 feet, 0.00 inches (1.219 meters), and weighed 1,320 pounds (599 kilograms).

This is the same airplane in which Jackie Cochran won the 1938 Bendix Trophy Race.

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. Longing, 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.

Screen Shot 2015-02-11 at 10.40.18Delta Queen was placed in scheduled service 15 May 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.

7 January 1980: In response to a challenge, Alan W. Gerhartner, 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.

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.

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.”

Identical to the Inglewood, California-built North American Aviation P-51B Mustang, this is a Dallas, Texas-built P-51C-1-NT, 42-103023. (North American Aviation, Inc.)
