The barrel roll out in Phoenix isn't new. When I was going through one person;
1. Barrel rolled the PA28
2. Did solo touch and goes out on desert roads
3. Exceeded (regularly) Vne.
4. When solo, got into the back seats of the aircraft and took a picture of the aircraft flying without a pilot.
5. Without any related training, did close formation flying with his mates.
I'm sure there was more and all passing through will remember him. He got a **** report and when I last heard was, thankfully, still looking for work.
