I think it has something to do with stuff becoming infinite.
Anyway, basically the effect is that my touchscreen stops working and several keys stop working. All I can do is zoom in and out and move the trim up and down using my keys. Here's what is in the dev console.

This happens on my iPad too. Every time it happens you have to close down and restart the game, which is annoying.

Ask for a link to the aircraft and I'll tag you (if you're a dev only). It's a secret tournament plane.
