Default [3e] Bede BD-5J Microjet

Bede BD-5J (TL7)
Holding the record for the world’s smallest jet, the BD-5J was designed by the father and son team of James R. and James A. Bede. The younger Bede wanted to bring aviation to enthusiasts by creating easy to assemble kit planes. The -5J required about 600 man-hours to assemble. The company did very well for 17 years, but ultimately could not complete with copycat competitors. In the early 1990s, James Bede tried to reestablish his presence in the market, but was killed in a test flight of the BD-10, another micro-jet that appears similar to an F-15.
A BD-5J was used in the opening scenes of the James Bond film Octo*****.
