3 February 1946: Pan American World Airways inaugurated the commercial operation of its new Lockheed L-049-46-21 Constellation, Clipper Mayflower, NC88836, with scheduled flights from New York to Bermuda. The Constellation flew the southbound route in 2 hours, 22 minutes.
On the same day, at 4:17 p.m., Eastern Standard Time, another Pan Am Constellation, under the command of Captain Robert D. Fordyce, departed LaGuardia Airport, New York, for London, England, with 30 passengers and a ton of cargo. The Lockheed made refueling stops at Gander, Newfoundland, and Shannon, Ireland, before finally arriving at Hurn Airport, Bournemouth, (approximately 100 miles southwest of London) at 7:50 a.m., EST, (12:50 GMT), 4 February, 1946. The total elapsed time was 15 hours, 32 minutes, with 12 hours, 49 minutes of actual flight.
According to Logbook Magazine, NC88836, Lockheed serial number 2036, was delivered to Pan Am on 5 January 1946. While with the airline it also carried the name Clipper Yankee Ranger. 2036 was transferred to Cubana de Aviación (owned by Pan Am since 1932) in 1953, and re-registered CU-T-547. It served with several other airlines over the next 15 years, including El Al Israel Airlines, registered 4X-AKE. The Constellation was taken out of service in 1968 and placed in storage at Tel Aviv. It was scrapped later that year.
The Lockheed Constellation first flew in 1942, and was produced for the U.S. Army Air Corps as the C-69. With the end of World War II, commercial airlines needed new airliners for the post-war boom. The Constellation had transoceanic range and a pressurized cabin for passenger comfort.

The Lockheed L-049 Constellation was operated by a flight crew of four and could carry up to 81 passengers. The airplane was 95 feet, 1 3⁄16 inches (28.986 meters) long with a wingspan of 123 feet, 0 inches (37.490 meters), and overall height of 23 feet, 7⅞ inches (7.210 meters). It had an empty weight of 49,392 pounds (22,403.8 kilograms) and maximum takeoff weight of 86,250 pounds (39,122.3 kilograms).
The L-049 was powered by four air-cooled, supercharged and fuel-injected, 3,347.662-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division Cyclone 18 ¹ 745C18BA3 two-row 18-cylinder radial engines with a compression ratio of 6.5:1. The -BA3 was rated at 2,000 horsepower at 2,400 r.p.m., or 2,200 horsepower at 2,800 r.p.m., for takeoff, (five minute limit). The engines drove 15 foot, 2 inch (4.623 meter) diameter, three-bladed Hamilton Standard Hydromatic constant-speed propellers through a 0.4375:1 gear reduction. The 745C18BA3 was 6 feet, 4.13 inches (1.934 meters) long, 4 feet, 7.78 inches (1.417 meters) in diameter and weighed 2,842 pounds (1,289.11 kilograms).
The L-049 had a cruise speed of 313 miles per hour (503.72 kilometers per hour) and a range of 3,995 miles (6,429.3 kilometers). Its service ceiling was 25,300 feet (7,711 meters).
22 C-69s and 856 Constellations of all types were built. Designed by the famous Kelly Johnson, the Lockheed Constellation was in production from 1943–1958 in both civilian airliner and military transport versions. It is the classic propeller-driven transcontinental and transoceanic airliner.

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.
Averages 450 M. P. H.
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.”
Captain Charles F. Blair, Jr., American Overseas Airlines.
Charles Francis Blair, Jr., was born 19 July 1909 at Buffalo, New York, the second child of Charles F. Blair, an attorney, and Grace Ethelyn McGonegal Blair. He entered the University of Vermont, where is father was a member of the Board of Trustees, as a freshman in 1927. He was a member of the Phi Delta Theta (ΦΔΘ) fraternity.
Blair was commissioned as an ensign in the United States Naval Reserve, 16 August 1932.
On 6 September 1932, Ensign Blair married Miss Janice Evelyn Davis at Wallingford, Vermont. They would have two children, Suzanne, born in 1934, and Christopher Noel, born in 1950. The Blairs would later divorce.
He was promoted to lieutenant, junior grade, 16 August 1937. During World War II, he served as a transport pilot in the U.S. Navy.
On 18 November 1952, Blair was one of three aviators to be awarded the Harmon Trophy. The presentation was made by President Harry Truman in a ceremony in The White House Rose Garden.
Blair resigned from the Naval Reserve in 1952 and the following year he accepted a commission in the U.S. Air Force Reserve with the rank of colonel. In 1959, Blair was promoted to brigadier general.
While serving as a reserve officer, Charlie Blair continued his civilian career as an airline pilot for United Airlines, American Overseas Airlines, and then with Pan American.
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).
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.)
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.

The Associated Press reported:
The 747 Age Is Here
LONDON (AP)—A Boeing 747 jetliner arrived in London from New York today on the maiden transatlantic commercial jumbo jet flight.
An overheated engine grounded the original aircraft and a substitute called Young America left New York at 1:52 a.m. EST, nearly seven hours after the scheduled departure time. The jet, carrying 332 passengers and 20 crew, touched down at London’s Heathrow Airport at 8:06 a.m. EST.
London Airport services were geared to deal as quickly as possible with the passengers and 30,000 pounds of baggage and cargo aboard the Pan American World Airways jumbo.
SOME PASSENGERS booked on the return flight to New York switched to other aircraft because of today’s delays, but a Pan Am spokesman said most of the passengers were waiting for the Jumbo.
The [sic] included actress Raquel Welch, who has been making a television spectacular in London.
The Boeing took 6 hours 15 minutes on the Atlantic flight. The pilot was Capt. Robert M. Weeks, 49, a veteran of 28 years with Pan Am who has logged more than 15,000 hours on Pan Am routes.
THE AIRCRAFT drew up at stand 1-29 on Heathrow’s Pier Five at 8:10 a.m., and passengers began disembarking four minutes later.
One of the passengers, Mrs. Joe Tepera of Fort Worth Tex., told newsmen: “The flight was simply great. Flying in a beautiful plane like that was worth the delay.
“All the passengers were good humored and when the plane finally took off they applauded. They did the same when it landed. I personally would not hesitate flying in a jumbo again.”
Michael J. Flynn of Chicago said: “The delay didn’t bother me much. We were given a first class meal. It’s a good plane.”
BUT ONE PASSENGER, who declined to be named, said he was annoyed at the service aboard the jumbo and the delay caused by switching planes in New York.
“The plane is simply too big for anyone to be given proper service,” he said.
Michael Brody, 21-year-old American who claims he wants to give away his multimillion-dollar fortune, was among the passengers.
“I am here for a rest. I am not going to give away any more money in Britain,” he told newsmen.
A Pan Am spokesman said the jumbo had been rechristened Young America in New York for the historic flight, but the aircraft carried the name Clipper Victor on its fuselage on arrival here.
THE HUGE PLANE made most of the smooth flight at 33,000 feet.
Richard Hobson, air correspondent of the British Press Association, who traveled on the jumbo, said: “From my position in one of the economy sections of the 747 where the seating is nine-abreast, divided by two aisles, was like being in a news theater. A film show—and the plane is equipped for them—would have completed the illusion.”
Pan Am has received five of the 33 jumbos ordered. Trans World Airlines plans to start jumbo service in March and British Overseas Airways Corp. will receive the first of 12 jumbos early in April and hopes to get them in service in June.
A British Airport Authority spokesman reported the first passenger cleared all baggage and airport formalities 34 minutes after the jet touched down.
“IT DOESN’T LOOK bad at all,” he said.
The spokesman gave this breakdown on times for clearing the jumbo’s passengers:
Time arrive 8:06 a.m. EST. Doors open: 8:19. First passenger off plane: 8:20 Last passenger off plane: 8:32. First passenger into baggage hall: 8:34. Last passenger into baggage hall: 8:57. First passenger into immigration: 8: … Last passenger out of immigration: 8:39. First passenger into customs: 8:25. Last passenger out of customs: 9:04. First passenger to clear airport: 8:46. Last passenger to clear airport: 9:05.

The 747-100 series was the first version of the Boeing 747 to be built. It was operated by a flight crew of three and was designed to carry 366 to 452 passengers. It is 231 feet, 10.2 inches (70.668 meters) long with a wingspan of 195 feet, 8 inches (59.639 meters) and overall height of 63 feet, 5 inches (19.329 meters). The interior cabin width is 20 feet (6.096 meters), giving it the name “wide body.” Its empty weight is 370,816 pounds (168,199 kilograms) and the Maximum Takeoff Weight (MTOW) is 735,000 pounds (333,390 kilograms).
The 747-100 is powered by four Pratt & Whitney JT9D-7A high-bypass ratio turbofan engines. The JT9D is a two-spool, axial-flow turbofan engine with a single-stage fan section, 14-stage compressor (11 high- and 3 low-pressure stages) and 6-stage turbine (2 high- and 4 low-pressure stages). The engine is rated at 46,950 pounds of thrust (208.844 kilonewtons), or 48,570 pounds (216.050 kilonewtons) with water injection (2½-minute limit). This engine has a maximum diameter of 7 feet, 11.6 inches (2.428 meters), is 12 feet, 10.2 inches (3.917 meters) long and weighs 8,850 pounds (4,014 kilograms).
The 747’s cruise speed is 0.84 Mach (555 miles per hour, 893 kilometers per hour) at 35,000 feet (10,668 meters) and it’s maximum speed is 0.89 Mach (588 miles per hour/946 kilometers per hour). The maximum range at MTOW is 6,100 miles (9,817 kilometers).

N736PA had initially been named Clipper Victor, but the name was changed to Clipper Young America for the inaugural New York to London flight when the 747 scheduled to make that flight—Clipper Young America—suffered mechanical problems. The 747 was hijacked on 2 August 1970 and flown to Cuba. After that incident, N736PA was renamed Clipper Victor — its original name. It was destroyed in a collision with another Boeing 747 at Tenerife, Canary Islands, 27 March, 1977.

The 747 has been in production for 53 years. As of January 2022, 1,569 747s of all models had been built. 205 of these were 747-100 series aircraft. On 12 January 2021, Boeing announced that the final 747s, four Boeing 747-8F freighters, had been ordered by Atlas Air Worldwide Holdings, Inc. The final Boeing 747, N862GT, was rolled out of the factory on 3 October 2022. The production of the “jumbo jet” has come to a close.

One of the first Boeing 707 airliners delivered to Pan American World Airways, N707PA. (Pan Am)
3 January 1981: Pan American World Airways retired its last Boeing 707 airliner. Pan Am had been the launch customer for the 707. On 20 October 1955 the airline ordered twenty 707s, and later ordered 130 more. The first one, Clipper America, a 707-121, N707PA, was delivered 15 August 1958. On 26 October 1958, N711PA, also named Clipper America,¹ made the first regularly scheduled transatlantic flight by a jet airliner.
The Boeing Model 707-121 was a four-engine jet transport with swept wings and tail surfaces. The leading edge of the wings were swept at a 35° angle. The airliner had a flight crew of four: pilot, co-pilot, navigator and flight engineer.
The 707-121 was 145 feet, 1 inch (44.221 meters) long with a wing span of 130 feet, 10 inches (39.878 meters). The top of the vertical fin stood 41 feet, 8 inches (12.700 meters) high. The 707 pre-dated the ”wide-body” airliners, having a maximum fuselage width of 12 feet, 4.0 inches (3.759 meters). The airliner’s typical operating empty weight is 122,500 pounds (55,565 kilograms). Maximum take off weight is 257,340 pounds (116,727 kilograms).

The first versions were powered by four Pratt & Whitney Turbo Wasp JT3C-6 turbojet engines, producing 11,200 pounds of thrust (49,820 kilonewtons), and 13,500 pounds (60.051 kilonewtons) with water injection. This engine was a civil variant of the military J57 series. It was a two-spool axial-flow turbojet engine with a 16-stage compressor and 2 stage turbine. The JT3C-6 was 11 feet, 6.6 inches (3.520 meters) long, 3 feet, 2.9 inches (0.988 meters) in diameter, and weighed 4,235 pounds (1,921 kilograms).
At MTOW, the 707 required 11,000 feet (3,353 meters) of runway to take off.
The 707-121 had an economical cruise speed of 550 miles per hour (885 kilometers per hour) at 35,000 feet (10,668 meters), and a maximum cruise speed of 593 miles per hour (954 kilometers per hour) at 30,000 feet (9,144 meters)—0.87 Mach. It’s range was 2,800 nautical miles (5,186 kilometers).
The Boeing 707 was in production from 1958 to 1979. 1,010 were built. Production of 707 airframes continued at Renton until the final one was completed in April 1991. As of 2011, 43 707s were still in service.

21 December 1988: Pan American World Airways’ Flight 103 was a scheduled transatlantic passenger flight, originating at Flughafen Frankfurt am Main (FRA) with stopovers at London Heathrow Airport (LHR) and John F. Kennedy International Airport (JFK), with a final destination of Detroit Metropolitan Wayne County Airport (DTW).
The first leg from Frankfurt to London was flown with a Boeing 727. The transatlantic segment of Flight 103 was flown by a Boeing 747-121, N739PA, named Clipper Maid of the Seas. It departed Heathrow at 1825 hours UTC, with 16 crewmembers and 243 passengers. The 747 climbed to the north and leveled off at at 31,000 feet (9,449 meters) at 1856 hours.
At approximately 1903, a time bomb which had been placed inside luggage carried in the airliner’s cargo hold detonated. Explosive decompression magnified the effects of the bomb. The airliner broke into five large sections and fell to the ground at the town of Lockerbie, Scotland.

All 259 persons on board the 747 were killed, as were another 11 persons on the ground.
The time bomb is believed to have been placed aboard the airliner by agents of the Great Socialist People’s Libyan Arab Jamahiriya, acting on orders of the Brotherly Leader and Guide to the Revolution of Libya, Muammar al-Gaddafi. One of these, Abdelbaset Ali Mohmed al-Megrahi, was convicted of 270 counts of murder in a Scottish criminal court seated in The Netherlands. The defense twice appealed the case, but prior to a decision in the second appeal, al-Megrahi dropped his appeal and asked to be released from jail because it was believed that he would very soon die of cancer. The Scottish court did release him and he returned to Libya on 14 August 2009, on board Colonel Gadaffi’s personal aircraft. He reportedly died 20 May 2012.
