1945-1965

Pan Am pioneers the Jet Age.

Commercial aviation takes a quantum leap forward with the introduction of jet powered aircraft

Global pioneer is launch customer

Some may find it surprising to learn that a single American airline, Pan American World Airways, was largely responsible for introducing the world to the pleasures of jet air travel. It was Pan Am who was the launch customer for the Boeing 707 and the Douglas DC-8, America’s first commercial passenger jets. 

Early attempts by Britain called “Magnificent False Start”

Pan Am was not the first airline to fly a commercial jet. That honor fell to British Overseas Airways Corporation (B.O.A.C.). Described by aviation historian R.E.G. Davies in his book, “Airlines of the Jet Age,” as “A Magnificent False Start,” on July 27, 1949, de Havilland Aircraft of Hatfield, England, launched a jet-engine prototype, the de Havilland D.H. 106. Following exhaustive testing, the D.H. 106, nicknamed the “Comet,” received its Certificate of Airworthiness in January of 1952 and entered service with B.O.A.C. between London and Johannesburg, on May 2, 1952. The Comet’s de Havilland Ghost jet engines halved the journey time of the most advanced piston-engined airliners, placing the Comet in a league of its own. Agog, the aviation world beat a path to de Havilland’s door.

Lacking trans-ocean range, the Comet was used for shorter haul routes. Between 1952 and 1954, four airlines — B.O.A.C., the French Union Aeromaritime de Transport (U.A.T.), South African Airways and Air France — operated Comets between Europe to Africa and Asia.

Then, on January 10, 1954, disaster struck. A Comet that had taken off from Rome exploded without warning near the Isle of Elba in the Mediterranean Sea. There was no clear cut explanation. Possible sabotage was suspected. Tests were inconclusive and the Comet was put back into service in March. Less than a month later, on April 8th, another Comet crashed into the sea near the island of Stromboli. An extensive inquiry resulted in a finding of “metal fatigue,” cracks which developed on top of the fuselage, the result of the differential in atmospheric pressure at which the new jet aircraft were being flown. De Havilland was forced to go back to the drawing board. Four years were to elapse before a reengineered Comet was to go back into service.

Enter Juan Trippe

Pan Am president Juan Trippe was a visionary with an uncanny ability to anticipate the future in order to ensure the success of his airline.  Despite Pan Am’s global reach and international dominance, in the post-war world, pressure on Washington from domestic carriers to fly international routes had become increasingly intense. At the same time, Pan Am’s efforts to be allowed to fly domestic routes had not met with success.  Facing this increasingly competitive landscape, in the early 1950s, Trippe took a bold step. While other airlines were lining up to buy Lockheed Electras and British Viscount turboprops, Trippe decided to skip that step and jump from piston engines directly to jets.  Starting in the late 1940s, Pan Am’s engineers began to work directly with Douglas, Boeing and Pratt & Whitney to design and build jet aircraft and engines which could meet Pan Am’s specifications for long-range jet travel.

After the tragic Comet disasters, with the exception of Pan Am, other U.S. commercial airlines were terrified of jets. Even U.S. aircraft manufacturers were initially reluctant to assume the risk of developing the new transport. Trippe astutely played Douglas and Boeing off of each other to get the planes and the designs he wanted.

The result was that, after years of collaboration between Pan Am’s Engineering Department and the manufacturers to bring the designs to fruition, Trippe was able to sign contracts with both Douglas and Boeing for jets in October 1955.

Trippe made the announcement about his order at a party he held for IATA executives in his New York apartment on October 13, 1955. As described by Robert Daley in his book, “An American Saga–Juan Trippe and his Pan Am Empire,” Trippe moved through the room, flashing his most cordial smile, shaking hands, mentioning in the most casual way that he had just bought forty-five jet airliners–20 Boeing 707s and 25 Douglas DC-8s.  As his guests realized the import of what they had just heard, “[W]hole corners of the room fell abruptly silent….Bewildering technical complexities lay ahead.  Billions of dollars in new capital would have to be raised.”  All the new turboprops the other airlines had on order were going to become obsolete the moment the jets started flying.  Many of the guests left early, says Daley.  A rush to reserve places on the production lines ensued.  

Pan Am’s Clipper America sparks headlines across the globe

The first Boeing 707 (a smaller plane than Trippe wanted but what Boeing could deliver at the time) was delivered in mid-1958. The maiden flight of Pan Am’s Boeing 707 Clipper America from New York to Paris took place on October 26, 1958, sparking headlines around the world. The new jet clippers flew at nearly 600 miles an hour and cruised at 30,000 feet or higher — “above the weather.” The huge planes were quieter and free of vibration as no other planes had ever been before.

“Nice try”

On October 4, a few weeks before Pan Am’s maiden Boeing 707 flight, BOAC got the jump on Pan Am, flying two reengineered de Havilland Comet 4 jets in opposite directions between New York and London. However, once Pan Am began its competing service with Boeing 707s, on October 26th, the writing was on the wall for the Comets. The Boeing’s swept-back wings were a more modern design than the Comet 4’s straight wings, and its greater length and wider fuselage provided far greater–and more profitable–passenger capacity over the Comet 4. The Boeing 707s could seat 189 passengers vs. the Comet 4’s 48. The B-707 also provided greater fuel economies and could be produced in far larger quantities than DeHavilland was capable of producing. B.O.A.C. had even gone as far as to hedge its bets, ordering 15 Boeing 707’s as early as 1956. By 1960, it was flying Boeing 707s on its transatlantic routes, using Rolls Royce (British made) engines instead of the Pratt and Whitney engines found on American models. The American jets were clearly the model for future long distance air transport. A corner had been turned and there was no going back.

Miami takes pride of place as southern hub of first domestic jet route

Domestically, the first ever jet route was flown by Florida’s own National Airlines, under a lease agreement with Pan Am. National leased Pan Am’s Boeing 707s for daily flights between Idlewild in New York City and Miami. The inauguration of the domestic jet service on December 10, 1958 was a coup for National. It also added yet another splendid trophy to Miami’s collection of aviation honors.

The first domestic airline to operate with its own Boeing 707s was American Airlines, on January 25, 1959. TWA followed on March 20th. On September 18, both Delta and United inaugurated scheduled passenger service on DC-8s, Delta between New York and Atlanta and United between San Francisco and New York. Delta soon added Miami to the list of cities served by DC-8s. Eastern Air Lines took a little longer. It officially joined the Jet Age on January 24, 1960, operating DC-8’s which it nicknamed “Golden Falcons.”
