Today in American Military History -- 1940
First successful test flight of an American helicopter, Vought-Sikorsky US-300
The Vought-Sikorsky VS-300 (or S-46) is an American single-engine helicopter designed by Igor Sikorsky. It had a single three-blade rotor originally powered by a 75 horsepower (56 kW) engine. The first "free" flight of the VS-300 was on 13 May 1940.[2] The VS-300 was the first successful single lifting rotor helicopter in the United States and the first successful helicopter to use a single vertical-plane tail rotor configuration for antitorque. With floats attached, it became the first practical amphibious helicopter.

The intro of birds and vertical envelopment created a paradigm shift in warfare during Korea. Besides the tactical advantages it increased survivability with WIAs. Marines still use the term "cut me a huss" for "give me a break", due to the USMC naming of the early birds (HUS-1, Sikorsky H-34/S-58).
