7 March 1961: Launched over Silver Lake, a dry lake bed near the California/Nevada border, at 10:28:33.0 a.m., Pacific Standard Time, test pilot Major Robert M. White, U.S. Air Force, flew the number two North American Aviation X-15 hypersonic research rocketplane, 56-6671, to Mach 4.43 (2,905 miles per hour/4,675 kilometers per hour) and 77,450 feet (23,607 meters), becoming the first pilot to exceed Mach 4.
This was the first flight for the number two X-15 with the Reaction Motors XLR99-RM-1 engine, which was rated at 57,000 pounds of thrust (253.55 kilonewtons).
The flight plan called for a burn time of 116 seconds, an altitude of 84,000 feet (25,603 meters) and a predicted maximum speed of Mach 4.00. The actual duration of the engine burn was 127.0 seconds. Peak altitude was lower than planned, at 77,450 feet (23,607 meters). The longer burn and lower altitude translated into the higher speed.
The total duration of the flight, from the air drop from the Boeing NB-52B Stratofortress carrier, 52-008, to touchdown at Edwards Air Force Base, was 8 minutes, 34.1 seconds.

North American Aviation P-82B-1-NA Twin Mustang 44-65168, “Betty Jo,” takes off from Hickam Field, 27 February 1947. (Hawaii Aviation)
27–28 February 1947: At 3:05 p.m., Hawaii Standard Time, (01:05 G.M.T.), Lieutenant Colonel Robert E. Thacker, Lieutenant John M. Ard, took off from Hickam Field on the island of Oahu, Territory of Hawaii, enroute non-stop to LaGuardia Airport, New York City, New York.
Thacker and Ard were assigned to the Air Materiel Command at Wright Field, Daytion, Ohio. Their airplane was a North American Aviation P-82B-1-NA Twin Mustang, 44-65168 (North American serial number 123-43754). The fighter had been named Betty Jo, in honor of Thacker’s wife. (The painter mistakenly applied the name as Betty Joe.)

Betty Jo had been modified by North American Aviation at El Segundo, California, in preparation for its long-distance flight. The fighter’s armor was removed, as were the six Colt MG 53-2 .50-caliber aircraft machine guns. Additional internal fuel capacity was added, and the P-82 was equipped with four large external fuel tanks. The Twin Mustang’s fuel capacity was 2,215 gallons (8,385 liters).

Thacker and Ard climbed to 13,000 feet (3,962 meters) after takeoff. As the fuel was burned off, the P-82 was able to climb higher. Most of the flight was made between 19,000 and 22,000 feet (5,791–6,706 meters).
After burning off the fuel in the four external tanks, Thacker tried to jettison them, but a mechanical problem prevented three tanks from being released. This resulted in adverse yaw and excessive drag for the overland portion of the flight. Colonel Thacker used the weight of his leg on the control stick to counteract the yaw.
Betty Jo, flying at 20,000 feet (6,096 meters), crossed the California coast near Point Arena at 12:34 a.m., Pacific Standard Time (08:34 G.M.T.), 6 hours, 59 minutes after takeoff. The P-82 passed north of Reno, Nevada, at 1:00 a.m. EST (09:00 G.M.T.), and Humboldt, Nevada, 23 minutes later.

Thacker and Ard next flew over Ogden, Utah, at 3:12 a.m., Mountain Standard Time (10:12 G.M.T.), and Laramie, Wyoming, at 4:05 MST (10:05 G.M.T.). They reported over Chicago at 6:49 a.m., Central Standard Time (12:49 G.M.T.), and Detroit at 8:38 a.m., CST (14:38 G.M.T.).
Betty Jo crossed overhead at LaGuardia Airport at 11:06 a.m., Eastern time (16:06 G.M.T.) and landed there at 11:08:34 a.m. (16:08:34 G.M.T.) The elapsed time from take off at Hickam Field to overhead LaGuardia was 14 hours, 31 minutes. The total duration of the flight was 14 hours, 33 minutes, 34 seconds.

On arrival at LaGuardia, only 60 gallons (227 liters) of fuel remained on board the Twin Mustang.
The Great Circle distance between Hickam and LaGuardia is s 4,324.32 nautical miles (4,976.34 statute miles/8,008.65 kilometers). Betty Jo averaged 297.89 knots (342.81 miles per hour/551.69 kilometers per hour) over the course.

Betty Jo is the ninth production North American Aviation P-82B-1-NA Twin Mustang. The airplane was designed toward the end of World War II as a very long range escort fighter operated by two pilots. It was built using two lengthened P-51H Mustang fuselages and standard left and right wings. A center wing section and horizontal stabilizer joined the two fuselages.
The P-82B was 39 feet, 1 inch (11.913 meters) long, with a wingspan of 51 feet, 3 inches (15.621 meters) and overall height of 11 feet, 10 inches ( meters) in three-point position. The airplane’s empty weight is 13,405 pounds (6,080 kilograms), and maximum gross weight, 22,000 pounds (9,979 kilograms).
The P-82B-1-NA Twin Mustang was powered by liquid-cooled, supercharged, 1,649-cubic-inch-displacement (27.04-liter) Packard V-1650-19 and -21 Merlin single overhead cam (SOHC) 60° V-12 engines. They drove counter rotating Aeroproducts four-bladed propellers. through a 0.479:1 gear reduction. The V-1650-19 was rated at 1,700 horsepower at 3,000 r.p.m. at 19¾ inches of boost for takeoff, with military power rating of 2,200 horsepower at 3,000 r.p.m. at Sea Level, and 1,875 horsepower at 17,000 feet (5,182 meters). At 1,770 pounds (803 kilograms), the V-1650-19 was the heaviest Packard Merlin variant produced.
The P-82B had a maximum speed of 482 miles per hour (776 kilometers per hour) at 25,100 feet (7,650 meters) and its service ceiling was 41,600 feet (12,680 meters). Its range was 1,390 miles (2,237 kilometers).
The P-82B was armed with six air-cooled Colt Automatic Aircraft Machine Guns, Caliber .50, MG 53-2, located in the center wing section, with 300 rounds of ammunition per gun. A pod containing eight additional .50-caliber machine guns could be installed under the center wing section. The Twin Mustang could also carry up to four 1,000 pound bombs, two 2,000 pound bombs, or twenty-five 5-inch rockets on underwing hard points.
After the United States Air Force was established as a separate military service in 1947, many aircraft designations were changed. The P-82B was redesignated as F-82B.

In September 1950, F-82B 44-65168 was transferred to the National Advisory Committee for Aeronautics (NACA) for use in testing ram jet engines at the Cleveland Aircraft Engine Research Laboratory. It was damaged in June 1957. The airplane was retired and turned over to the National Museum of the United States Air Force.
Robert E. Thacker was born 21 February 1918 in California. He was the second of four children of Percie C. Thacker and Margaret Eadie Thacker.
in 1939, Thacker was appointed an aviation cadet in the Air Corps, United States Army, and trained as a pilot at Brooks Field, San Antonio, Texas. He was commissioned a second lieutenant, Air Reserve, 21 June 1940.
On 3 March 1941, 2nd Lieutenant Thacker married Miss Betty Jo Smoot at Yuma, Arizona. They would be married for 71 years until she died in 1992.
On 1 November 1941, Thacker was appointed a first lieutenant, Army of the United States (A.U.S.).

North American Aviation production test pilot George Franklin Smith with a North American F-100A Super Sabre (NASM)
26 February 1955: Although it was his day off, North American Aviation production test pilot George Franklin Smith stopped by the office at Los Angeles Airport (today, known as Los Angeles International airport, or simply “LAX”, its FAA airport identifier). The company’s flight dispatcher told him that a brand-new F-100A-20-NA Super Sabre, serial number 53-1659, was sitting on the flight line and needed to be test flown before being turned over to the Air Force.

Smith was happy to take the flight. He departed LAX in full afterburner and headed off shore, climbing to 35,000 feet (10,668 meters) over the Pacific Ocean to start the test sequence.
A North American F-100A-1-NA Super Sabre, 52-5757 (the second production airplane) takes off at Los Angeles International Airport. (This airplane, flown by NAA test pilot Bob Hoover, crashed east of Palmdale, California, 7 July 1955, when he could not recover from a flat spin. Hoover safely ejected but the Super Sabre was destroyed.) (North American Aviation, Inc.)
But it was quickly apparent that something was wrong: The flight controls were heavy, and then there was a hydraulic system failure that caused the Super Sabre pitch down into a dive. Smith couldn’t pull it out of the dive and the airplane’s speed rapidly increased, eventually passing Mach 1.
Smith was unable to regain control of the F-100. He had no choice but to bail out. As he ejected, Smith read the instruments: the Mach meter indicated Mach 1.05—785 miles per hour (1,263 kilometers per hour)—and the altitude was only 6,500 feet (1,981 meters).

The force of the wind blast hitting him as he came out of the cockpit knocked him unconscious. Estimates are that he was subjected to a 40 G deceleration. His parachute opened automatically and he came down approximately one-half mile off Laguna Beach. Fortunately he hit the water very close to a fishing boat crewed by a former U.S. Navy rescue expert.
The F-100 dived into the Pacific Ocean approximately ¼-mile (0.4 kilometers) offshore between Dana Point and Laguna Beach.
George Smith was unconscious for six days, and when he awoke he was blind in both eyes. After four surgeries and seven months in the hospital, he recovered from his supersonic ejection and returned to flight status.

George F. Smith appears in this brief U.S. Air Force informational film:
The North American Aviation F-100 Super Sabre was designed as a supersonic day fighter. Initially intended as an improved F-86D and F-86E, it soon developed into an almost completely new airplane. The fuselage incorporated the “area rule,” a narrowing in the fuselage width at the wings to increase transonic performance, similar to the Convair F-102A.
The Super Sabre had a 49° 2′ sweep to the leading edges of the wings and horizontal stabilizer. The ailerons were placed inboard on the wings and there were no flaps, resulting in a high stall speed in landing configuration. The horizontal stabilizer was moved to the bottom of the fuselage to keep it out of the turbulence created by the wings at high angles of attack. The F-100A had longer wings and a distinctively shorter vertical fin than the YF-100A. The upper segment of the vertical fin was swept 49° 43′.

There were two service test prototypes, designated YF-100A, followed by the production F-100A series. The first ten production aircraft (all of the Block 1 variants) were used in the flight testing program.
The F-100A Super Sabre was 47 feet, 1¼ inches (14.357 meters) long with a wingspan of 36 feet, 6 inches (11.125 meters). With the shorter vertical fin than the YF-100A, the initial F-100As had an overall height of 13 feet, 4 inches (4.064 meters), 11 inches (27.9 centimeters) less than the YF-100A.
The F-100A had an empty weight of 18,135 pounds (8,226 kilograms), and gross weight of 28,899 pounds (13,108 kilograms). Maximum takeoff weight was 35,600 pounds (16,148 kilograms). It had an internal fuel capacity of 755 gallons (2,858 liters) and could carry two 275 gallon (1,041 liter) external fuel tanks.
Following North American Aviation test pilot George Welch’s fatal accident, 12 October 1954, NACA designed a new vertical fin for the F-100A. It was taller but also had a longer chord. This resulted in a 10% increase in area. (NASA E-1573)
The early F-100As were powered by a Pratt & Whitney Turbo Wasp J57-P-7 afterburning turbojet engine. It was rated at 9,700 pounds of thrust (43.148 kilonewtons) for takeoff, and 14,800 pounds (65.834 kilonewtons) with afterburner. Later production aircraft used a J57-P-39 engine. The J57 was a two-spool axial flow turbojet which had a 16-stage compressor, and a 3-stage turbine. (Both had high- and low-pressure stages.) The engine was 15 feet, 3.5 inches (4.661 meters) long, 3 feet, 5.0 inches (1.041 meters) in diameter, and weighed 4,390 pounds (1,991 kilograms).

The Super Sabre was the first U.S. Air Force fighter capable of supersonic speed in level flight. It could reach 760 miles per hour (1,223 kilometers) at Sea Level. (Mach 1 is 761.1 miles per hour, 1,224.9 kilometers per hour, under standard atmospheric conditions.) Its maximum speed was 852 miles per hour (1,371 kilometers per hour) at 35,000 feet (10,668 meters)—Mach 1.29. The service ceiling was 44,900 feet (13,686 meters). Maximum range with external fuel was 1,489 miles (2,396 kilometers).
The F-100 was armed with four M-39 20 mm autocannons, capable of firing at a rate of 1,500 rounds per minute. The ammunition capacity of the F-100 was 200 rounds per gun.
North American Aviation built 199 F-100A Super Sabres at its Inglewood, California, plant before production shifted to the F-100C fighter bomber variant. Approximately 25% of all F-100As were lost in accidents.

The Mustang had been designed and built by North American Aviation, Inc., as a fighter for the Royal Air Force. Two Mustang Mk.I airplanes, the fourth and the tenth from the RAF production line, had been given to the Air Corps for evaluation and designated XP-51, serial numbers 41-038 and 41-039. Prior to this, the Air Corps had ordered 150 P-51 fighters, but these were Mustang Mk.I models to be turned over to England under Lend-Lease.
43-6003 was used for testing and was equipped with skis for takeoff and landing tests in New Hampshire and Alaska.
The second production North American Aviation P-51A-NA Mustang, 43-6004, (99-22107) was used for high-speed testing. It was called Slick Chick. (U.S. Air Force)
The North American Aviation P-51A Mustang was a single-seat, single-engine, long-range fighter. It is a low-wing monoplane with retractable landing gear and is of all-metal construction. It was 32 feet, 2½ inches (9.817 meters) long with a wingspan of 37 feet, ¼-inch (11.284 meters) and a height of 12 feet, 2-½ inches (3.721 meters) high. It had an empty weight of 6,451 pounds (2,926 kilograms) and gross weight of 8,000 pounds (3,629 kilograms).

The P-51A was powered by a right-hand tractor, liquid-cooled, supercharged, 1,710.60-cubic-inch-displacement (28.032 liter) Allison Engineering Company V-1710-F20R (V-1710-81) single overhead cam (SOHC) 60° V-12 engine with a compression ratio of 6.65:1. The V-1710-81 had a Maximum Continuous Power rating of 870 horsepower at 2,600 r.p.m., at Sea Level, and 1,000 horsepower at 2,600 r.p.m. at 14,400 feet (4,389 meters). It was rated at 1,200 horsepower at 3,000 r.p.m. for takeoff. The Military Power rating was 1,125 horsepower at 3,000 r.p.m., to an altitude of 14,600 feet (4,450 meters). War Emergency Power was 1,480 horsepower. The engine drove a 10 foot, 9 inch (3.277 meter) diameter, three-bladed Curtiss Electric constant-speed propeller through a 2:1 gear reduction. The engine was 7 feet, 1.87 inches (2.181 meters) long, 3 feet, 0.75 inches (0.933 meters) high and 2 feet, 5.28 inches (0.744 meters) wide. It weighed 1,352 pounds (613 kilograms).

Maximum speed of the P-51A in level flight was 415 miles per hour (668 kilometers per hour) at 10,400 feet (3,170 meters) at War Emergency Power. It could climb to 20,000 feet (6,096 meters) in 7 minutes, 3.6 seconds, and to 30,000 feet (9,144 meters) in 15 minutes, 4.8 seconds. Its service ceiling was 35,100 feet (10,699 meters) and the absolute ceiling was 36,000 feet (10,973 meters). Maximum range on internal fuel was 750 miles (1,207 kilometers).
The P-51A was armed with four Browning AN-M2 .50-caliber machine guns, with two mounted in each wing. The inner guns had 350 rounds of ammunition, each, and the outer guns had 280 rounds per gun.
Of the 1,200 P-51A Mustangs ordered by the Army Air Corps, 310 were delivered. The order was changed to the Packard V-1650 Merlin-powered P-51B Mustang.

Robert Creed Chilton was born 6 February 1912 at Eugene, Oregon, the third of five children of Leo Wesley Chilton, a physician, and Edith Gertrude Gray. He attended Boise High School in Idaho, graduating in 1931. Chilton participated in football, track and basketball, and also competed in the state music contest. After high school, Chilton attended the University of Oregon where he was a member of the Sigma Chi fraternity (ΣΧ). He was also a member of the Reserve Officers Training Corps (ROTC).
Bob Chilton enlisted as an Aviation Cadet in the U.S. Army Air Corps, 25 June 1937. He was trained as a fighter pilot at Randolph Field and Kelly Field in Texas, and was commissioned as a Second Lieutenant in 1938. Lieutenant Chilton was assigned to fly the Curtiss P-36 Hawk with the 79th Pursuit Squadron, 20th Pursuit Group, at Barksdale Field, Louisiana. Because of a medical condition, he was released from active duty, 1 April 1939.
At some time prior to 1940, Bob Chilton, married his first wife, Catherine. They lived in Santa Maria, California, where he worked as a pilot at the local airport.
In January 1941, Chilton went to work as a production test pilot for North American Aviation, Inc., Inglewood, California. After just a few months, he was assigned to the NA-73X.
Chilton married his second wife, Betty W. Shoemaker, 15 November 1951.
On 10 April 1952, Bob Chilton returned to active duty with the U.S. Air Force, with the rank of lieutenant colonel. He served as Chief of the Republic F-84 and F-105 Weapons System Project Office, Air Material Command, at Wright-Patterson Air Force Base, Dayton, Ohio, until 9 March 1957.
From 1958, Chilton was a vice president for Horkey-Moore Associates, an engineering research and development company in Torrance, California, founded by former North American aerodynamacist Edward J. Horkey. In 1961, he followed Horkey to the Space Equipment Corporation, parent company of Thompson Industries and Kerr Products, also located in Torrance. Chilton served as corporate secretary and contracts administrator.
Chilton married his third wife, Wilhelmina E. Redding (Billie E. Johnson) at Los Angeles, 26 July 1964. They divorced in 1972.
In 1965, Bob Chilton returned to North American Aviation as a flight test program manager. He retired in 1977.
Robert Creed Chilton died at Eugene, Oregon, 31 December 1994, at the age of 82 years.
Charles F. Blair, jr. arrives at Heathrow. (Getty Images)
31 January 1951: Pan American World Airways Captain Charles F. Blair, Jr., flew a modified North American Aviation P-51C-10-NT Mustang, NX1202, named Excalibur III, from New York International Airport to London Airport in 7 hours, 48 minutes, with an average speed of 446 miles per hour (718 kilometers per hour). Captain Blair took advantage of the jet stream, flying as high as 37,000 feet (11,278 meters).
“At last, I was riding the jet stream, pushed by a tailwind exceeding 200 miles per hour. . . Above me, the sky was empty and blue; below the wings of my tiny aircraft a winter storm raged. Its upper canopy of white clouds gave it a look of complete innocence.”
—The Salt Lake Tribune, Sunday, 3 June 1951, Page 115
This was Blair’s 401st Atlantic crossing.
Blair’s flight did not set an official record. No arrangements had been made to have officials of the Fédération Aéronautique Internationale (FAI) available to observe the flight.

Interestingly, Excalibur III was impounded by HM Customs at the London Airport. Blair had not paid the £800 customs duty which would have allowed the Mustang to stay for six months. He would have had to fly the airplane back to the United States to avoid the aircraft being impounded.
The Chicago Daily Tribune reported the event:
LONE PILOT HOPS OCEAN IN LESS THAN 8 HOURS
LONDON, Jan. 31 (AP)— Air Line Capt. Charles Blair landed his scarlet Mustang fighter plane in a blaze of red flares tonight, chalking up a New York to London speed record of 7 hours 48 minutes. He clipped an hour and seven minutes off the old record.
Blair said his only troubles during the flight were some icing in the early stages and a painfully tight pair of boots.
As he climbed from the cockpit of the flying gas tank named Excalibur III and waved to a cheering crowd at London airport he winced and declared: “The first thing I do is get these boots off.”
Aided by Tail Winds
Blair left New York’s Idlewild airport at 3:50 a.m. Chicago time [09:50 UTC] and was clocked in here at 5:38 p.m. British time [11:38 a.m. Chicago time]. [17:38 UTC]
A Pan American Airways pilot, Blair took the time record from a Pan American Stratocruiser which made the eastward Nov. 22, 1949, with 24 passengers, in 8 hours and 55 minutes. Strong tail winds helped in both cases.
Blair, tall, dark, married, and 41, brought no luggage, but had a shaving kit and a tooth brush in a small leather bag.
His plane is powered by a Packard built Rolls-Royce Merlin engine and was modified to hold 863 gallons of gasoline inside wings and fuselage without external tanks. He said the plane cost $25,000 to buy and revamp.

Blair told newsmen at London airport: “It was a very good crossing. It wasn’t as fast as I expected, but after Gander, N.F., I had a tail wind of 130 miles an hour. But the weather wasn’t too good and there was some ice.”
Blair’s average speed was about 450 miles an hour and he made much of the jaunt at 37,000 feet.
He said the trip had a dual purpose, to break the record and to study the effect of high velocity winds on airliners in the lower stratosphere.
Blair will fly back to New York as a passenger in a Stratocruiser. He has to return by Saturday. On that day he will fly a planeload of passengers from New York to London.

Blair was presented the Harmon International Trophy by President Harry S. Truman in a ceremony at the White House, 18 November 1952. The Harmon awards are for “the most outstanding international achievements in the art and/or science of aeronautics for the previous year, with the art of flying receiving first consideration.”

On 12 March 1968, Captain Blair married to actress Maureen O’Hara, whom he had met during one of his 1,575 transatlantic crossings. It was the fourth marriage for both.
Captain Blair made his final flight with Pan American in July 1969. He had flown more than 45,000 hours and traveled more than 10,000,000 miles.
Blair was the author of Thunder Above (Henry Holt & Co., 1956), a novel co-written with A.J. Wallis and filmed as “Beyond the Curtain,” starring Richard Green and Eva Bartok, in 1960. He also wrote Red Ball in the Sky (Random House, 1969), an account of his career in aviation.
Brigadier General Charles Francis Blair, Jr., died 2 September 1978 in an airplane accident. His remains were interred at the Arlington National Cemetery.

Excalibur III is a Dallas, Texas-built North American Aviation P-51C-10-NT Mustang, one of a group of 400 fighters which had been contracted on 5 March 1943. Its North American Aviation serial number is 111-29080, and the U.S. Army Air Force assigned it serial number 44-10947.
After World War II, 44-10947 was transferred to the Reconstruction Finance Corporation (a Depression-era agency of the United States government) at Searcy Field (SWO), Stillwater, Oklahoma. It was purchased by Paul Mantz, 19 February 1946, and the Civil Aeronautics Administration registered it as NX1202. Mantz had the Mustang painted red and named it Blaze of Noon. (Mantz was a movie pilot and aerial coordinator for the 1947 Paramount Pictures movie, “Blaze of Noon,” which was based on the Ernest K. Gann novel, Blaze of Noon, published in 1946.)
Paul Mantz flew NX1202 to win the 1946 and 1947 Bendix Trophy Races. Flown by Linton Carney and renamed The Houstonian, NX1202 placed second in the 1948 Bendix race, and with “Fish” salmon in the cockpit, it took third place in 1949.

Paul Mantz had set several speed records with the Mustang before selling it to Pan American World Airways, Inc., Blair’s employer. Blair named the Mustang Stormy Petrel, but later changed it to Excalibur III.
To increase the Mustang’s range for these long-distance flights, Mantz had removed the standard 90-gallon pressure-molded Firestone self-sealing tanks from each wing and converted the entire wing to a fuel tank (what is known as a “wet wing”).
The P-51B and P-51C Mustang 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), slightly faster than the more numerous P-51D Mustang. 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.
Though the P-51D with its bubble canopy was built in far greater numbers during World War II, the earlier P-51B and P-51C Mustangs were actually faster, so many surplus airplanes were used for racing and record attempts after the war.
In 1952, Pan American World Airways donated Excalibur III to the Smithsonian Institution. The airplane’s registration was cancelled 4 June 1952. Today, completely restored, it is on display at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.
