In 1930 Carl T von Cosel, of Key West FL. Built a two-place cabin, high-wing monoplane amphibian, registered N879Y and powered by a 180hp LeRhône rotary engine.

 

The wings were never attached, so the plane was never flown. Some reports claimed that von Cosel, an undertaker by trade, kept his dead wife in it for an unstated period of time.

 

When he left Key West in 1940, he took the plane with him and both disappeared.
