About aerobatics and parachutes, someone said that it's hard to escape from a rolling plane because you can't open the doors, what about canopies? It seems that there are a lot of aerobatic planes which have canopies, not doors.
Most aero aircraft either have jettison able doors or a canopy that can be opened or got rid off, if not aero then you are unlikely to have a chute!
Sevenstroke seems determined that you change your instructor, it MAY be something to think about, but this question should not be the sole reason, you could end up changing from one you get on with to one that pushes too much or causes you other problems, only you know what your instructor is like, though I do agree that questions like this
should be answered by him.
