a couple here seem to think that it is uncool to make funny comments about this incident. my observations: models and track meets never ever go together. ever. i dont need hindsight to know that. second, people everywhere. not good. lastly, of course the pilot is going to say radio issues. no other good explanation is left. it did throttle back in my opinion, was just going too fast. however, maybe it was a radio issue. i can say this with confidence, i wouldnt have been running my jet at a track meet with people everywhere. so a few humorous comments are acceptable in my opinion. i bet this guy probably wont do this kind of demo again.
