Moller 200X

The Moller 200X, the invention of Paul Moller, a former professor of aerodynamics and engineering, is built of graphite, carries computers, and eight lightweight Wankel engines. The proof of concept 200X is a flat, round 10 foot wide saucer, which can hover out of ground effect.

First flown in February 1989, the machine, which flew more than 150 times, is to make way for the production version, the Merlin.
