Scotty McCray flew a Schweizer 2-22 EK for his demonstrations. We appeared
at the same shows many many times and I knew him quite well.
The 2-22 wasn't exactly the "cleanest" glider in the world by today's
standards. Scotty was an absolute master at energy control. His technique
for energy management was in my opinion the best I've ever seen done in an
unpowered aircraft. I think I watched Scotty perform hundreds of barrel
rolls in the 2-22 and never once did I see him dish it out of a roll.
Strangely enough, it was the addition of horsepower to his aerobatics that
killed him down in Brazil in 73, when the Decathlon he dished out of a low
altitude roll.
One of the nicest and finest guys I knew in aviation.

What does "dished out" mean?
