Hall subsequently designed a more sophisticated development of the Model 116, with a more refined car body and a more powerful "flight" engine.

In the Aerocar 2000's case, the flight engine is a twin-turbocharged V-8 motor from a Lotus Esprit.

At the same time, a contract was placed for a "flight engine", the W.1.

Holly fired up all four flight engines, tumbling the shuttle into the abyss.

This is the first of a series of Taurus II engines to be tested at Stennis to include acceptance testing of flight engines.

In 1942 he received his doctoral thesis from Stuttgart University for a work on "Valve control systems for four-stroke flight engines."
