If the plane never leaves the ground it isn't an airplane as far as I'm
concerned. Think how easy it would be to just put together some cardboard
and a light jet engine and call it the lightest jet airplane.

Couldn't someone toss a couple of those model plane jet engines on an
ultralight and take the record for smallest jet? It would take some
research to select the right plane but I'd go with one of Chuck's planes...
