"I'm sure glad you don't teach on any of my airplanes, because bent nose wheels and bent propellers are very expensive"
--mmmhhh what to make of this? I think I'll stick with the instructor who values mine and his life above the nosewheel of the aircraft rather than the owner who appears to favour the reverse.
You have read my comment in the wrong context.
A competent flight instructor will ensure his students do not have an accident or incident of any kind period.
To suggest that breaking nose wheels and propellers is acceptable as long as you do not lose control in the air and spin in is an astounding comment.
Lets try this another way.
If this were driving a car would you have someone working for you who was only interested in the renters not smashing into highway over passes at high speed but beating the hell out of the car parking it was O.K.?
