The Arup S-2. The Flying Heel Lift.

by Daniel Russ on February 16, 2014







Dr. C.L. Snyder, A podiatrist from South Bend, Indiana tossed a heel lift through the air and was inspired to build a plane on that design. He envisioned a huge glass wing 100 feet long and thick enough to hold passengers and allow them to view their trip unoccluded. In 1932 he formed the Arup Manufacturing Corporation and began building flying prototypes of blended wing planes. He called them the S-4 and the S-4. Raoul Hoffman helped him bring to life a few of the most successful planes that never went to market despite good performance and an accident free life. The S-4 featured a low aspect ratio, circular planform wing, one of many that also never caught on commercially.

Seeing the caption of the video, the first S-4 probably should be S-2? “He called them the S-4 and the S-4”
