Before the jets, Pan Am was less an airline than an instrument of American policy abroad. It began in 1927 with one mail contract to Havana. Soon Washington treated it as its "chosen instrument" and gave it every foreign airmail route put out to bid. With that business Juan Trippe built the Clippers, the flying boats that opened scheduled service across the Pacific in 1935 and the Atlantic in 1939. The price was a ban on flying inside the United States.

Mail to Havana, autumn 1927

The first Pan American Airways was not Juan Trippe's company. It was incorporated on 14 March 1927 by a group of investors, and the idea came from Army officers, Hap Arnold among them, who worried that German aviation in South America threatened the Panama Canal (Pan Am Historical Foundation). In July the company won FAM 4, a temporary contract to carry American mail to Cuba, with service due to start in October. Trippe had a company of his own. With the financiers Cornelius Vanderbilt Whitney and William Rockefeller he had formed the Aviation Corporation of America on 2 June 1927.

The pieces came together at the last moment. On 11 October 1927 Pan American Airways became part of a new corporate structure with Trippe as president and general manager. The Post Office terms were blunt: fly the mail from Key West to Havana by 19 October or lose the contract. Eight days after the reorganisation Cy Caldwell flew the first mail, 250 pounds of it, to Havana in a Fairchild FC-2 seaplane chartered from West Indian Aerial Express (University of Miami Libraries). Trippe was 28. Scheduled service began nine days later, and in January 1928 the first paying passengers made the 90-mile trip in one hour and ten minutes.

That year Trippe also signed the most famous aviator alive. Charles Lindbergh became Pan Am's technical adviser and stayed on its board in that role for 45 years. He brought more than his name. Shortly before, he had flown the Spirit of St. Louis nonstop from Washington to Mexico City and then on around Central America, the north of South America and the Caribbean. Pan Am later surveyed those routes, and they turned up, "not coincidentally" in the words of the Pan Am Historical Foundation, in the Post Office's contract specifications (Pan Am Historical Foundation).

The 1928 law and the chosen instrument

In the 1920s no airline could live without guaranteed revenue, and for Pan Am that meant mail contracts. On 8 March 1928 Congress passed the Foreign Air Mail Act and soon set aside $1.75 million to pay for the system. Pan Am won the Havana contract again, now at $2 a mile, and moved the start of the route from Key West to Miami. In July the Post Office gave it two more routes out of Havana: west through Mexico to Panama, and east to Puerto Rico.

The law suited a company like Pan Am. As the Coolidge administration and its commerce secretary, Herbert Hoover, wanted, only airlines able to operate on a scale that would "project the dignity of the United States in Latin America" could carry international mail, and only if the countries concerned had invited them. Trippe made sure Pan Am had no competition (U.S. Centennial of Flight Commission). On 23 June 1928 Atlantic, Gulf and Caribbean Airways, Pan American Airways and the Aviation Corporation of America merged into the Aviation Corporation of the Americas; Trippe's group held 40 percent of the stock, and a new Pan American Airways Incorporated became the main operating company. Washington, the commission writes, came to see Pan Am as its "chosen instrument" for foreign policy, a way to push American business into Latin America and the Caribbean, and it awarded Pan Am every foreign airmail route it put out to bid.

There was a price. Pan Am was barred from domestic routes in return for exclusive rights abroad. Its exclusive hold abroad lasted until the Second World War, the domestic ban until 1978 (Smithsonian). That ban is where the story of why Pan Am failed begins.

How much the arrangement cost the taxpayer became a political argument. In 1944 TIME summed up Matthew Josephson's critical book Empire of the Air. By his count the first Miami - Havana contract paid Pan Am $160,000 a year, Pan Am collected most of the $123 million the Post Office spent on foreign mail from 1928 to 1941, and in 1940 domestic airlines were paid a third of the rates Pan Am received (TIME, 1944).

The routes carried strategy as well as letters. On 9 January 1929 Pan Am dedicated its new Pan American International Airport in Miami. On 4 February Lindbergh took off in the Sikorsky S-38 NC8000 to open the route to Panama through Mexico and Central America, with one passenger aboard: Juan Trippe. It took three days to reach France Field in the Panama Canal Zone, which the foundation calls the most critical point of American defence in the Western Hemisphere.

Latin America and the first Clippers

South America was a contest. On the west coast Pan Am had to deal with W. R. Grace, the shipping company. Their joint airline, Panagra, founded on 25 January 1929 with each side putting up half the capital, was flying from Miami to Peru by May and to Santiago by July (Pan Am Historical Foundation).

On the east coast the rival was NYRBA, Ralph O'Neill's New York, Rio and Buenos Aires Line. Its 14 Commodore flying boats, the foundation says, outclassed anything Pan Am had. Trippe worked Washington instead, where Postmaster General Brown was determined to give the foreign mail contract to Pan Am. On 19 August 1930 NYRBA's main backer, James Rand, agreed to sell his share to Trippe's company for 40 cents on the dollar, and on 15 September NYRBA was absorbed into Pan American Airways. Offered a job, O'Neill refused: "They can steal my house, but they can't make me run it for them".

Across the Caribbean, Mexico and Central and South America Pan Am built what did not yet exist: airfields, weather stations and radio navigation aids. It flew boats because most of its Latin American destinations lay on the coast, and a boat did not have to contend with the rough state of early airfields.

The first boats to carry the famous name were three Sikorsky S-40s. With 38 seats and a crew of six, the S-40 was the largest American airliner of its day, and it was the first to be called a Clipper, a name every later Pan Am aircraft would carry (Smithsonian). The first of them, the American Clipper, was delivered in October 1931. On 19 November it left Miami for Barranquilla in Colombia with Basil Rowe and Lindbergh at the controls and Igor Sikorsky in the cabin (Pan Am Historical Foundation).

Across the Pacific: the S-42 and the China Clipper

The ocean needed a new aircraft. The 32-seat Sikorsky S-42 entered service in 1934 and could carry twice as many people twice as far as the Douglas DC-2. Pan Am was its only launch customer and bought all ten, and with them it began to survey routes across the oceans (Pan Am Historical Foundation).

Europe stayed closed. Britain would not let Pan American land on British soil until Imperial Airways could fly to the United States in return, and Trippe waited years for an Atlantic agreement (Pan Am Historical Foundation). The Pacific route could be flown under the American flag all the way: Hawaii, Midway, Wake, Guam and the Philippines.

The weak link was Wake. The atoll was the only place in 3,000 miles where Pan Am's flying boats could land to refuel on the way to Guam and Manila, and it belonged to the United States (Pan Am Historical Foundation). Builders landed there in early May 1935 from the ship North Haven and had to distil their drinking water from the sea. On 17 August 1935 a survey S-42 reached Wake. Its first leg, from Alameda to Pearl Harbor, had taken 17 hours 12 minutes for 2,078 miles.

On 22 November 1935 the Martin M-130 China Clipper took off from San Francisco. It carried no passengers. Its cargo was 58 mail pouches holding 111,000 envelopes, almost 2,000 pounds, then the largest load of mail ever put aboard an aircraft, and nearly all of it came from collectors who wanted a first-flight cover (National Postal Museum). Captain Edwin Musick was in command, and his navigator was Fred Noonan. The Clipper reached Manila on 29 November after 59 hours 48 minutes in the air; the fastest steamship needed 15 to 16 days.

The M-130 was the first airliner that could fly the 2,400 miles from San Francisco to Honolulu without stopping, and three were built for Pan Am (Smithsonian). On Midway and Wake Pan Am built its own hotels. Paying passengers followed on 21 October 1936 aboard the Hawaii Clipper (Pan Am Historical Foundation). The one-way fare was $799, few could afford it, and the flying boats usually carried no more than eight passengers.

The Pacific also cost lives. On 11 March 1937 New Zealand broke ranks with Australia and Britain and let Pan Am fly there, and when Musick brought the Samoan Clipper in, 30,000 New Zealanders turned out to greet him. On 11 January 1938, after taking off from Pago Pago in the same flying boat, he began dumping fuel because of an oil leak; vapour collected in the wing, and the flying boat exploded in mid-air. By then, in the company's words, he was the most famous pilot in the world.

The Atlantic, 1939

Trippe had prepared for the Atlantic years in advance. On 21 July 1936 Pan Am signed a contract with Boeing for six Model 314s (Boeing). Trippe bought them specifically for the planned transatlantic route. The 314 could fly up to 3,500 miles and, on shorter stages, carry up to 74 passengers and a crew of 10 (Smithsonian).

On 3 March 1939 the First Lady christened the Yankee Clipper. In his speech Trippe spoke of the 5,000 men and women of the Pan American system at posts in the United States and 46 foreign lands, and claimed that in ten years the Clippers had brought the nation "from last to first place on the airways of the world" (Pan Am Historical Foundation).

The regulators gave their approval on 12 May 1939, and five mail-only proving flights followed. On 20 May the Yankee Clipper circled over the New York World's Fair with the first airmail for Europe. It opened the first scheduled transatlantic airmail service, from Port Washington, New York, to Marseilles, exactly 12 years after Lindbergh's solo crossing (Smithsonian). On 24 June the mail began flying the northern route to the British Isles via Newfoundland and Ireland.

On 28 June 1939 the Dixie Clipper left Port Washington for Lisbon and Marseilles by way of Horta in the Azores with 22 paying passengers (Pan Am Historical Foundation). Betty Trippe was among them. In her diary she called it the "first airplane flight to carry passengers to Europe" and compared the trip with the sailing ships that had needed two or three months: "yet we were crossing in twenty-four hours". Sixty-three days later Germany invaded Poland.

By the middle of the decade, the foundation writes, the Clippers had been crossing the Pacific while Pan Am subsidiaries flew in China and Alaska; by its end the Boeing 314s linked every continent of the Northern Hemisphere (Pan Am Historical Foundation). The Centennial of Flight Commission counts the Clipper fleet at 25 flying boats over both oceans.

Pan Am at war

During the Second World War Pan Am flew more than 90 million miles for the American war effort. It carried troops and cargo, ferried bombers, built 50 airports in 15 countries and trained thousands of military pilots, navigators and mechanics (University of Miami Libraries). Pan American Airways-Africa, set up in July 1941 after talks between the American and British governments, flew from Miami through South America and across the Atlantic to West Africa, over the Sahara to the Middle East and India, and over the Himalayas into China (Pan Am Historical Foundation).

The war found one Clipper on the far side of the world. When Pearl Harbor was attacked on 7 December 1941, Captain Robert Ford's Boeing 314 Pacific Clipper was two hours short of Auckland. Ordered to fly home westward under radio silence, the crew had no charts, and the navigator bought an atlas at a library in New Zealand. On 6 January 1942 the flying boat landed at LaGuardia in New York after 37 days, 18 stops and 31,500 miles (Boeing).

A year later a Clipper carried the president. In January 1943 Franklin Roosevelt flew to the Casablanca Conference aboard the Boeing 314 Dixie Clipper, the first sitting president to travel by air (National Archives).

The same war killed the flying boat. The Army, working with Pan American, laid concrete runways across the Caribbean, northern South America, the South Atlantic and Africa toward India and China (Smithsonian). Pan Am itself used them to replace its luxurious but inefficient flying boats with four-engine land planes. After the war the DC-4, the DC-6 and the Constellation ruled long-distance flying, and by 1951 the last Boeing 314s had sunk in Baltimore harbour.

After the war: one airline among several

Before the war Pan Am had been the only American international airline. Presidents Roosevelt and Truman both felt the country would be better served by several overseas airlines, and after the war the Civil Aeronautics Board ended Pan Am's exclusive hold on overseas routes (Smithsonian). Trippe opposed it. In the spring of 1944, TIME reported, 17 of the 19 American airlines wanted wide-open competition on foreign routes, while Trippe argued for the chosen instrument (TIME, 1944). He did not drop the idea. In 1962 TIME wrote that he had preached it since the early 1940s: American airlines could compete with subsidised foreign carriers only if Washington named a single American airline to fly overseas. No administration took his advice (TIME, 1962).

Pan Am kept growing all the same. By 1947 it employed 19,000 people in 62 countries (University of Miami Libraries). Trippe bought pressurised Boeing 307s and Lockheed Constellations, and in 1947, eleven years after his own trip to Hong Kong on the Philippine Clipper, a Constellation opened Pan Am's first round-the-world service (Pan Am Historical Foundation). By the end of the decade Pan Am was also selling cheaper fares. In 1950 American Overseas Airlines, the former American Export Airlines that American Airlines had taken over after the war, became part of Pan Am (Pan Am Historical Foundation).

Tourist class and forty-five jets

Trippe's next fight was over price. In May 1943 he told an audience in New York that air transport could become a luxury for the well-to-do or "carry the average man at what he can afford to pay", and that Pan American had chosen the second (Pan Am Historical Foundation). In 1945 he announced a New York - London fare of $256. The other members of IATA, the airlines' association, held out for $375 one way, and the attempt failed (Pan Am Historical Foundation).

Only in 1952 did IATA give way. From 1 May every member airline could sell a tourist-class round trip from New York to London for $486; for years the round trip had cost $711. Pan Am was ready with the Douglas DC-6B. It had taken delivery of the first, Clipper Liberty Bell, in February, and in its tourist layout, which Pan Am called Rainbow Service, the DC-6B carried 82 passengers against about 60 in a Constellation. On the first day TWA and El Al got away first, at 12.01 and 12.09 a.m.; Pan Am's DC-6B left Idlewild for London later that day. On 10 September 1957 Pan Am opened DC-7C flights from California to London over the pole, and the tourist fare was then $720.

Then Trippe bet on jets. In October 1955, at a gathering of the world's airline chiefs, Trippe announced that he had just ordered 45 jets for $269 million: 25 Douglas DC-8s and 20 Boeing 707s (Pan Am Historical Foundation). "Apart from Juan Trippe, the aviation world was terrified of jets," Robert Daley writes in An American Saga. Almost exactly 31 years after the first 90-mile flight to Havana, the first Pan Am Boeing 707 left New York for Paris. That flight opens the next part of the Pan Am series.
