NeilCP,
I have a fond memory of the Vampire. My one and only ride on an ejection seat was in a T11 at Shawbury. My flight included practice PARs for the radar trainees and I remember being surprised that I needed 45° of bank for a Rate 1 turn and that I didn't need to use the rudders.
I was also suitably impressed by the ejection seat briefing before the flight, being told that the seats were the same as in Valiants and that I would probably have a back injury if I had to use it. Sitting on a live seat for the first time certainly focuses the mind.
