Pan Am Across the Atlantic

Eyes on the Atlantic
Pan American had its eyes on the Atlantic market almost from the beginning of the airline’s history. The crossing between Europe and America was one of the most heavily traveled passenger routes in the world; in 1925, about a million passengers crossed the North Atlantic. The world’s largest and most prestigious ocean liners were in service on the North Atlantic, and the passage between Europe and the United States boasted more first class passengers (and potential airline customers) than any other steamship route; about 180,000 passengers crossed the Atlantic in first class in 1925. Perhaps even more importantly, a tremendous quantity of mail (the keystone of any airline’s revenue in the early days of commercial aviation) as well as express packages and valuable freight carried between Europe and the United States.
Pan American assumed that its natural expansion, after its success in Latin America, would be across the Atlantic, and the requirements of a transatlantic crossing dictated Pan American’s specifications for a new aircraft in the early 1930’s, which would become the S-42 and M-130. Pan American also made early investments in the route, including the purchase of landing rights from the government of Iceland for $55,000 in 1932. But political and diplomatic roadblocks, primarily set by the British, frustrated Pan Am’s ambitions to offer service across the Atlantic, which remained stalled for most of the 1930’s, even as the German airships Graf Zeppelin and Hindenburg began regularly scheduled passenger and mail service between Europe and America.
Resistance from the British
The main obstacle was that Britain did not want the United States to have a monopoly — or even a head-start — on a transatlantic airline service, and refused to grant landing rights in Britain itself or the British-controlled stepping stone across the Atlantic, such as Atlantic Canada and Bermuda. Similar rivalry from Portugal also frustrated attempts to inaugurate a southern route with stops in the Azores and Lisbon on the southern route.
The British insisted on reciprocity, and would not grant landing rights to an American airline until Britain’s Imperial Airways was able to commence a similar service. On January 25, 1936, Juan Trippe and George Woods-Humphrey, Managing Director of Imperial Airways, signed an agreement dividing transatlantic service between Pan American and Imperial Airways; the agreement eliminated competition from other airlines, such as the Dutch, French, and Germans, who were barred from the British stepping stones across the Atlantic, but it provided that neither Pan Am nor Imperial Airways could begin service until both airlines able to do so. Since Britain was far behind America in flying boat technology, and Imperial Airways did not have any aircraft capable of transatlantic service in 1936, Pan American would have to wait more three years before its planes could fly the Atlantic.
The first crack in the wall of British resistance occurred in early 1937, under the threat of competition from airships and alternative technologies, such as the German sea-air catapult mail service, which did not require landing permits on British-controlled territory. Pan Am began construction of flying boat bases Baltimore, New York City, and Port Washington, Long Island, and other bases were built at Shediac, in the Canadian province of New Brunswick; Botwood in Newfoundland, not far from Gander Lake; and at Foynes, on the River Shannon in Ireland.
Pan American Service to Bermuda
The first step in creating a reciprocal British-American transatlantic service was the opening of service between the United States and Bermuda. While Imperial Airways’ principal flying boat in 1937, the Short Brothers S-23, did not have the range to cross the Atlantic, it was able to make the 775 mile flight between Bermuda and New York. (Although the British flying boat could not reach Bermuda on its own, and had to be disassembled and sent by ship across the Atlantic.) On May 25, 1937, the Imperial Airways flying boat Cavalier, and Pan American’s S-42B Bermuda Clipper, left Bermuda and Port Washington at the same time for survey flights on the route. Regular service by both airlines began on June 18, 1937.
Surveying the Atlantic – 1937
With Anglo-American cooperation on the horizon, Pan Am began surveying the route across the Atlantic. On June 25, 1937, a Pan American S-42B named Pan American Clipper III, fitted with extra fuel tanks and under the command of Captain Harold Gray, flew from New York to Shediac and back, without landing. And additional flight to Gander followed, and on July 3, 1937, Imperial Airways and Pan American made the first reciprocal survey flights across the North Atlantic. The British flying boat Caledonia crossed westward, while Captain Gray’s Pan American Clipper III flew the route from New York to Shediac, Botwood, and Foynes. An additional survey flight was made on the southern route from New York to Bermuda, the Azores, Lisbon, and Marseilles.
The path to transatlantic airliner service seemed clear. But the British said no. Their flying boat had only been able to cross the Atlantic with everything from the seats to the flooring stripped out and replaced with fuel tanks, and the British had no plane capable of flying the transatlantic route with passengers or even mail. The Hindenburg disaster of May, 1937 eliminated the treat of transatlantic competition by airships, and the British retreated to their earlier position: No service by Pan American until Imperial Airways could commence service as well. Pan Am’s transatlantic ambitions were put on hold for another two years. But by the time Pan American was finally allowed to cross the Atlantic with mail and passengers, it had a new advantage over its British rivals: the B-314 Boeing Clipper.
The First Transatlantic Flights
On May 20, 1939 — only twelve years, to the day, after Charles Lindbergh crossed the Atlantic in his single-engine Spirit of St. Louis — Pan American’s B-314 Yankee Clipper departed Port Washington, New York for the first scheduled mail service across the Atlantic. The Clipper carried 112,574 pieces of mail (mostly from stamp collectors), four dozen California marigolds for Britain’s Queen Mary, and 16 Pan Am employees under the command of Captain Arthur E. La Porte. The ship flew the southern route across the Atlantic, landing in Lisbon the next afternoon after flight of approximately 27 hours (which included a stop at Horta in the Azores), and then flew to its final destination in Marseilles, France the next day.
The Yankee Clipper also made the first mail flight on the northern route across the Atlantic, to England, on June 24, 1939, with stops at Shediac (New Brunswick), Botwood (Newfoundland), and Foynes (Ireland).
Passenger service began a few days later, on June 28, 1939, when the Dixie Clipper left New York with 22 passengers on the southern route to Horta, Lisbon, and Marseilles. The passengers — who had paid $375 for a one way ticket, or $675 for a round trip — included Southern Railway executive William J. Eck, who received a silver cigarette case for being the first paying passenger on the route; renowned “first flighter” Clara Adams, who was on the first leg of a record breaking, round-the-world flight; Juan Trippe’s wife, Mrs. Elizabeth Stettinius Trippe; United States Lines president John M. Franklin; Texas Corp. (Texaco) chairman Torkild Rieber, who was forced from his position just a few months later for his overly close business relations with Nazi Germany; investment banker Harold Leonard Stuart; and American-Hawaiian Steamship Company president Roger Lapham.
On July 8, the Yankee Clipper introduced Pan Am’s service on the northern route across the Atlantic, carrying 17 passengers to England. The era of transatlantic heavier-than-air passenger service had arrived.

Thanks for a fascinating website — I came across it while trying to find out about an interesting item that I inherited from my great uncle. It’s a US Dollar bill, with “American Clipper 3317″ and “31 May 1945″ written on it, along with several signatures. I was told that it was a souvenir of the restarting of Clipper flights across the Atlantic. Can anyone give me any further information or ideas? I would be very grateful, thanks!

That was known as a short snorter; you have found a great little piece of history!

Thank you very much for this information. I can now see that one of the “signatures” actually reads “short snorter”!

Great site, look forward to more interesting details of these flights. I am wanting to know
of the Yankee Clipper crash. I was told by my mom long ago that a courier friend of theirs
died in the mishap. Does anyone know where I can get reports on crash victims, dead and survivors?
Also, if anyone who worked at Foynes Terminal during WWII is still in Ireland, I’d love
to communicate to learn of those times.

I had only ever seen references to these amazing aircraft in the movies, and I accidentally ran across your excellent website and spent an hour here! What a wonderful adventure it must have been to travel on these aircraft, especially compared to today’s cattle-car mentality. Thank you for an enjoyable and educational hour.
Best wishes,

To the site administrator – thank you very much for this site and for having so many wonderful pictures here in such high quality!
I happen to live near the spot where the only fatal accident involving a 314 took place. The docks where the clippers moored in the 40s were converted to the site of the world exhibition of 1998 and is now the location of the lisbon oceanarium. Unfortunately, none of the original buildings stand but at least the dock remains.
Kind regards!

Rui, love to get reports of the Yankee Clipper crash rescue, names of dead and survivors.
My parents’ good friend died on that flight (I know singer Jane Froman survived with bad
injuries). Any ideas who I should contact?

I am interested in your information on the crash R.O.D. Sullivan the pilot in command of the flight. I am doing a video on the China Clipper first trans Pacific flight on 11/22/35. He was the copilot on that flight. I want to tie in all the crew members of that first Pacific flight, The Capt. Ed Musick was killed in Pago Pago, The navigator Fred Noonan when down with Amelia Earhart. Sullivan crashed in the Tagus River, I would like to read your article. Still researching the other crew members of the Pacific Flight.

I’ve read contradictory information about the Yankee Clipper flight that originated in New York on May 20, 1939.
On May 23, 1939 did it land in Southampton, or did it just circle Southampton and landed it at Hythe?

Help!!! I’m urgently trying to find a photo I saw 4-5 years ago, not sure where. It showed three large seaplanes, probably docked in Portugal. They were lined up in a row – one had USA flag on it, one had a big swastika, and I think the 3rd was British. I am sure this was just before or even during WW2, as Portugal was neutral. Any help will be greatly appreciated. The USA plane was likely a Pan Am Martin M-130 Clipper or a Pan Am Boeing 314 Clipper. I knew a radio-navigator who flew the route into Portugal at this time. Thanx, desperate in Arizona, JA

My wife’s Grandfather was Frederick Stanley Mockford, originator of the “Mayday” signal whilst Radio Officer at Croydon Airport, London. He was in attendance at the “Transatlantic Rhythm” Cele bration Reception at Claridges Hotel, London on the 8th July 1937 and had the pleasure of meeting all of the crew of The Clipper and to get their autographs. Being a senior manager for Marconi Wireless and Telegraph Company, he often went on various flights regarding wireless reception, etc. Would you be kind enough to inform me IF he was a passenger on the Clipper flight as I am trying to write his autobiography. Many Thanks.

If I had the money, I’d be at the Foynes Flying Boat Museum for Foynes Festival 6th – 12th July 2009. (http://www.flyingboatmuseum.com/) Margret O’Shawesse has a beautiful museum and I’ve always wanted to go there. Ah well, maybe next year. If I sell a few more books.
Cheers! Jamie
