This Me-163 'Komet' is another pre-painted Japanese 'Gashapon' model. It didn't even require much assembly. An interesting WW2 'Vonder Veapon', the Komet was designed around a rocket motor to get very high up very quickly in order to then pour a load of 30mm cannon shells into a nice tight formation of B-17s or B-24s.
30+ years ago I read a book by a chap who'd been one of the development pilots. I understand this wasn't a long-term career option.
After what must have been a hair-raising takeoff the wheels were jettisoned (and later re-used). A couple of minutes later the fuel in this militarised firework ran out and then it was back home (if you were lucky) for a precarious landing on the glider-style skid.. What could possibly go wrong?
