span the ocean once its crews had shipped in what was required to create a commercial airbase out of nothing. Similarly, Midway, Guam, Pago-Pago and Kingsman Reef were also famed refueling and rest facilities created by the company’s own personnel. It was these mid-oceanic bases that enabled the Glen Martin M-130 China Clipper, built to Pan Am’s specifications, with a range of 3,200 miles (5,150 km) and 41 passengers, to reach Manila from Hawaii. The fleet of three Clippers carried 1,986 passengers during the first year of service, starting November 22, 1935. The struggle between Pan Am and the British aviation authorities to start a transatlantic service with the Boeing B314 delayed the proving flights until the British had increased the fuel capacity of its Shorts C-class (Empire class) boats; though this gave them a still air range of 3,780 miles (6,080 km), the payload was zero. The Pan Am S-42 could only make it between Newfoundland (a British dominion) and Foynes, Ireland with a favorable tail wind. The Boeing B314 with its potential 3,500 mile (5,632 km) range was seriously delayed by design problems; the sponson stabilizers angle, shape and size allowed the boat to tip a wing under water at normal taxi speeds and took complete rework to get them right. An even more dangerous problem was at touchdown—it would bounce and porpoise and could be mitigated only by landing at high speed in a fl at approach or very slowly with a high nose-up angle. After a staved-in hull at Horta, Azores, both Pan Am’s Harold Gray (then chief pilot Atlantic Division and future president) and Boeing’s George Schairer (of future swept-wing fame) rode the model test rig in the NACA, Langley Field, VA, laboratories and found they couldn’t take off or land properly. It was not until a block of wood was fastened to extend the hull step 20 inches (50.8 Humphery, his job for allowing it. There is a bronze plaque marking the event in the Manhasset dock parking lot. The Shorts Empire C-class boats were eventually modified for in-flight refueling by three Handley Page Harrow transports with one stationed off Ireland and two out of Newfoundland. This gave them a range of 2,500-plus miles (4,000 km) and a payload of 4,270 pounds (1,937 kg). Imperial Airways then took delivery of three B314s and operated them during WWII between Lisbon and Baltimore. It was deemed too dangerous to fly to southern England, and New York’s Manhasset Bay was prone to icing during the winter. An old time crew member told me that prior to the U.S. entering the war they would carry mail from Lufthansa flights into Lisbon. PHOTO COURTESY OF NASA. The Fabre Hydravion became the first recorded seaplane to take flight in 1910. B314 Accidents: cms) further aft that the boat became docile over the complete range of landing speeds. Modifying the actual flying boats by a one frame extension of the hull step made them a dream to fly. Eventually, the British agreed to the start of transatlantic service (one per week by each company) but it cost Imperial Airways (forerunner of B.O.A.C./ BA) managing director, George Woods- Connect with Your Business Community Join Today! February 22, 1943: The Yankee Clipper landing on Lisbon’s Tigris River at dusk in a dead calm, made a low turn to touch down, a wing tip struck the water and the ship cartwheeled and broke up. Of the 39 on board, 24 were killed. November 14, 1945: The Honolulu Clipper ditched in the Pacific after a double engine failure and was sunk by the U.S. Navy after it collided with the tow ship. No fatalities. October 14, 1947: The Cape Town Clipper, now owned by American International Airways, ditched in the Atlantic after running out of fuel when powerful head winds reduced its ground speed to 59 mph (94 km); sunk by the Cost Guard as a danger to shipping. It required over 1,200 20mm shells to send it to the bottom. No fatalities. With the Lockheed 049 Constellation and Douglas DC-4 in regular transatlantic service by 1946, Pan Am retired their remaining six “Queens of the Skies”.
