Here's another good one I've done... Start at 15,000 above the airport. Dive down and execute an inside loop (as low as possible to the ground). Reaching the top of the loop, shutdown both engines. See if you can complete the loop and safely land.

We would try to see how hot we could get the T-6 engines on start... I saw somewhere near 2200...

My instructor has been prone to pausing me about 20 feet from touchdown. He then brags about how I was denyed. I then turn around and ask him whats going on. At that point in time he unfreezes me and then counts how many bounces I can do.
My record is 7.
