Sorry about the crash. I was going to join those complaining about your instructor, but the quotes above make me first want to ask, who was holding the radio with the instruction switch? Not that I think you should have been holding it, just wondering.

Instructors should always have the live radio, and should not hesitate to let go of the switch. I find it easy to explain why I took control, but fatigued or nervous students usually have to be asked if they want a rest. Students in trouble shouldn't be asked, the switch should be released. I usually let go of the switch and say "The reason I took control is...." as I'm straightening out the plane.

Good luck on the next planes!

Best wishes,
Dave Olson
