Again, not a stall, and the T-Bird pilot, a friend of mine, misjudged his altitude at the top of the loop. . .mistakes do happen.

Stall, separation of smooth airflow over the wing, loss of lift, meaning no lift generated because of disrupted airflow. The Hunter and the T-Bird did not stall. They were flying. An aircraft that is stalled is not flying.

Nice short explanation here: http://www.allstar.fiu.edu/aero/flight55.htm

And a very short vid (by a friend of mine): https://www.youtube.com/watch?v=5wIq75_BzOQ

Cheers.

Terminology. In the head-on photo just before impact, you can see the condensation from separation of smooth airflow over the wing. That separation causes a loss of lift so the aircraft mushes.
