This is the world's smallest jetplane. It was designed and developed by Jim Bede, with help by Burt Rutan. It goes 350 mph on a 400-lb. thrust engine. The prototype was first fitted with a 200-lb. thrust engine, then one that developed 300 lbs. The final 400-lb. version used an engine borrowed from a small, German-made twin-engine jet. It's said that this larger engine gave better mileage in the BD 5J than the smaller ones. I've heard that this may have been 20 mpg or more, which is pretty good for any jet.This demonstration was flown by Jack Eckel (sp.?), a former Blue Angels pilot. It's the model that Corkey Fornof flew through an open hangar in the James Bond movie, "Octopussy". Unfortunately, the plane in this video had a fuel-line sensor burst in flight a few years later and a fire forced the pilot to bail out, who survived. At least 3 pilots have been killed in BD 5J crashes and several more in the BD-5 propeller-driven model. One of them was Scott Manning, a former pro football player who was 6' 3" and weighed 215 lbs. It's not certain how many of the BD 5J planes that were produced are still flying, although none seem to be currently on the airshow circuits.More information: www.airplanemart.com/aircraft-history-and-specification/Bede
