I understand that a Tornado F3 mate, whilst out at Akrotiri on APC, decided to see what height he could reach. Full burner, accelerate to speed of heat, pitch to the vertical...and wait until V/S reached zero. All was going quite well until both engines decided not to play...and it wasn't until he'd lost a lot of height trying to regain control and restart that he began to breathe more easily.
Allegedly, a certain very unpopular WIWOL Air Marshal was all for throwing the book at him for flying his aircraft outside release-to-service limits.
Until, I was told, someone happened to ask the Air Marshal whether Lightning reheat rotation take-offs were within the Lightning's R-to S.
Whereupon the atmosphere became rather...chilly. F3 mate was simply told "Don't do it again!"
Hmmm...
