29 March 1949
On 29 March 1949, the North American Aviation P-51C Mustang, NX5528N, Thunderbird, with Joe Claiborne DeBona in the cockpit, took off from the Lockheed Air Terminal, Burbank, California, at 6:20:50 a.m., Pacific Standard Time (13:20:50 UTC) and flew across the North American continent to land at LaGuardia Airport in New York City at 2:20:50 p.m., Eastern Standard Time (18:20:55 UTC).
This flight was timed by Fred H. Wilkerson of the National Aeronautic Association, at 5 hours, 0 minutes, 5 seconds. The official distance flown was 2,453.085 statute miles (3,947.858 kilometers), with an average speed of 490.625 miles per hour (789.584 kilometers per hour). This established a new U.S. national speed record.
When interviewed after his cross-country flight, DeBona was quoted as saying:
“I had a couple of scares,” DeBona admitted. “Over Akron, Ohio, I began losing oil pressure. The gauge showed a pressure of 20 when it should have read a normal 70. I thought the ball game was over right then but we kept on.
“Then, above Sunbury, Pennsylvania, I ran out of oxygen. Now I was really scared. I dove to 17,000 and stayed there. Just as I was approaching LaGuardia, a porst-side canopy window cracked like a pistol shot but did no damage. I was coming into the field at 600 miles an hour so I couldn’t afford any serious trouble.”
—Daily News, Vol. 30, No. 238, 30 March 1949, Page 2C, Column 4
Joe DeBona had made two prior unsuccessful transcontinental record attempts with Thunderbird. On March 6, he was forced to land at Smoky Hill Air Force Base, Salina, Kansas. (Some contemporary news reports said that the problem was a fuel pump, while others said it was an oil pump.) On 24 March, Thunderbird‘s propeller governor failed near Pueblo, Colorado. DeBona aborted the attempt and returned to Burbank, California.
Joe DeBona had purchased NX5528N from Leland H. Cameron, 7 April 1948. The airplane had been assembled from salvaged parts of other Mustangs. The earliest document in the airplane’s file with the Federal Aviation Administration (successor to the Civil Aeronautics Authority), Form ACA 132, contains the hand-written notation, “no service no.” The document states, “THIS AIRCRAFT WAS ASSEMBLED FROM COMPONENTS OF OTHER AIRCRAFT OF THE SAME TYPE.” The aircraft is designated on the form as a North American P-51C, Serial No. 2925. It was registered to the Joe De Bona Racing Co., which was owned by Academy Award-winning actor and World War II bomber pilot, James Maitland (“Jimmy”) Stewart.
On 31 August 1948, following an airworthiness inspection, C.A.A. Inspector Homer L. Stamets issued an original Airworthiness Certificate to NX5528N. The “Experimental” classification was used as there was no civil Type Certificate for North American’s P-51 fighters, and the C.A.A. had not tested or accepted the aircraft for any civilian use. The Experimental classification placed severe restrictions on De Bona’s use of Thunderbird. In the Operations Authorized section of the certificate it states, “Certificated for the purpose of Racing and Exhibition flights only; flights limited to the Continental limits of the UNITED STATES. Flights prohibited over thickly populated areas or large gatherings of people.” The certificate was valid for one year.
Originally assembled with a Packard V-1650-3 engine, this was changed to a V-1650-7 for the 1949 racing season. DeBona flew Thunderbird in the Bendix Trophy Race, winning first place with an average speed of 470.136 miles per hour (756.611 kilometers per hour).
Jimmy Stewart sold Thunderbird to Jackie Cochran, 19 December 1949. On that same day, she flew the Mustang to set an FAI world speed record. She set another FAI record with NX5528N in 1951. In 1953, she sold Thunderbird back to Stewart.
Stewart changed the Mustang’s paint scheme and renamed it Mr. Alex, in honor of his father, Alexander Maitland Stewart.
After changing hands again, N5528N was destroyed in a crash 15 miles (24 kilometers) north-northeast of Morrill, Nebraska, 22 June 1955.¹

10 February 1960
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 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.
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
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 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.
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
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.
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.
Mooney M20K N231LR was issued an Airworthiness Certificate on 27 December 1978. It is currently registered to a private party in West Sacramento, California.
¹ FAI Record File Number 13854: Speed Over a Recognised Course, 486.20 kilometers per hour (302.11 miles per hour), 7 January 1980. Current Record.
² FAI Record File Number 965: Speed Over a Recognised Course, 352.36 kilometers per hour (218.95 miles per hour). FAI Record File Number 966: Speed Over a Recognised Course, 384.03 kilometers per hour (238.63 miles per hour). Both records were set 1 January 1977.
