The Martin Model 130 also had a very large fuel capacity, which gave it a range of over 3,000 miles. Only three were built: the China Clipper, Philippine Clipper, and Hawaii Clipper. #WingWednesday #AvGeek

The Martin Model 130 flying boat was designed to meet #PanAm's requirements for a long-range, transoceanic aircraft to cross the expanse of the Pacific. It had a clean, aerodynamic design and was equipped with “sea wings” for buoyancy, instead of sponsons. #WingWednesday #AvGeek

As rival United Air Lines had exclusive rights to the Boeing 247, TWA (Transcontinental & Western Air) turned to Douglas Aircraft to develop an improved competitor. The Douglas DC-2 was developed in the early 1930s and introduced in 1934. #WingWednesday #avgeek

The DC-2 could carry 14 passengers, and proved a safe, reliable, and comfortable airliner with a maximum speed of 210 mph. Fewer than 200 were built, as its successor, the DC-3, one of the most successful airliners ever, was introduced the following year. #WingWednesday #avgeek

#OTD in 1982, the Boeing 757 took its first flight. Designed to be more fuel efficient than its predecessor, the trijet 727, the twinjet 757 was used by airlines around the world on short- to medium-range flights. Over 1,000 of the aircraft were built. #AvGeek

Advanced for its time, the Boeing 247 accommodated only ten passengers, which made it less economical to operate than larger capacity airliners, particularly the more fuel-efficient, fourteen-seat Douglas DC-2, introduced a year later in 1934. #WingWednesday #avgeek

Although the Sikorsky S-40 served #PanAm well through the 1930s, it was often derided for its lack of aerodynamic efficiency due to its many struts and support wires. Charles Lindbergh famously referred to the aircraft as a “flying forest.” #WingWednesday #AvGeek

Only three Sikorsky S-40 were built, and these were the first to be named “Clipper Ships.” #PanAm introduced the aircraft in 1931, piloted by Charles A. Lindbergh on its Miami–Barranquilla route. #WingWednesday #AvGeek

The Sikorsky S-40 was developed in response to requests from #PanAm president Juan T. Trippe for a high-capacity flying boat. With a cabin capable of carrying 38 passengers, it was nearly double the capacity of the airline’s next largest flying boat. #WingWednesday #AvGeek
