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 This tweet was posted on January 27, 2021.

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 This tweet was posted on January 27, 2021.

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 This tweet was posted on January 27, 2021.

The all-metal Ford Tri-Motor, or “Tin Goose,” had a huge impact on commercial aviation in the late 1920s and 199 were produced.
