The Sikorsky VS-300 hovering under the watchful eyes of its inventor, Igor Sikorsky (standing). The VS-300 was the first successful single lifting rotor helicopter in the US and the first successful helicopter to use a single vertical-plane tail rotor configuration for antitorque. With floats attached (as in this image), it took off and landed from the water in 1941, thus also becoming the first practical amphibious helicopter. From Vertiflite, May/June 1974 (page 5).
