Way back when I was going through USAF flight training, I was flying with a guest Instructor on an instrument flight in the T-33.
One of the requirements was the unusual attitude thing which was usually a piece of cake. After all I was under a big hood in the back seat. So maybe I cheated a bit when told to close my eyes. We went through the basics of nose up, inverted and descending turns. All just fine. THEN:
The instructor shakes the stick, reaches back to raise the hood, and waves his hand in front of his mouth to signal No-Talk. If I had a brain it was definitely not working as The "Hot" mike allowed one to monitor the other's breath. [:'(] Then he wrote a note and passed it under the rudder pedals. Now consider I was dressed in Jet-Pilot stuff, helmet, O-2 mask, shoulder harness, seat belt, crotch belt, boots, Bail-out bottle (o-2, not gin) on the parachute harness, and bending down to get that note was the most important thing -- or so I thought -- I could do. After much shuffling and directed attention to the chore, I opened the note to see the word, "RECOVER". Well I was in some 60*+ nose down at some way past 90* bank angle and approaching the red-line on the airspeed indicator with a vertical velocity pegged beyond the 6000 ft per minute descent point.
I did it, and will never forget it. It was the best lesson ever. In those days, Instructors did not laugh much, but we both did after that ride. (28 started in my class, 13 graduated)
When I later went back and instructed in the T-33 I used that trick on every student where basic instruments were performed.
NOT ONE ever complained. Each thought it was the best thing ever.
Unfortunately the T-38 had two cockpits and the trick could not be done.

The lesson learned is, "FIRST FLY THE AIRPLANE" Those old words Aviate, then communicate, then navigate.
In 41 years of professional aviation it was always true.

I still apply such in its way when I instruct RC students. Safety is part of everything they do and planning ahead is most important.
