A good while ago I spent a winter working on a desk job in Eastern Canada. I decided to get a checkout at the local flying club. As it turned out the airplane I was given was a C150 Aerobat . The instructor doing the check out was a low time officious twa*t and I was getting pretty fed up by the half way point with the final straw being the “surprise” unusual attitude I was warned to expect at any time. The instructor set up a mild spiral dive and in an imperial tone ordered me to recover. So I continued the roll to knife edge, ruddered the nose to the horizon and did a quarter slow roll to level.
The instructor looked at me with very wide eyes and said “ What was that !” . My reply “ That is how pilots who are confident in their ability to fly the airplane no matter what attitude it is, do”
The flight ended quickly and he did not have much more to say......
