T4 Bang Seats
I thought this one had been laid to rest. I went through Bassingbourn, finishing in February 1957, and at that time the pilots in the T4 still did not have ejector-seats - the RH one rolled back to let Bloggs get across to the LH. And you didn't go solo in the T4. Instead, you went for a 45 minute famil ride on the Rumbold seat of a B2 with your instructor driving and your nav, with a nav instructor, in the back. The staff then got out, engines running, and left the pair of you to get on with it.
Ejector seats (Mk3?) for T4 pilots appeared in the early 60s and you then (coincidentally?) did go solo in the T4 before you flew the B2 or PR3. Anyone know when it changed?
