Well, we did (damn politicos again)
XH558 is the only airworthy Vulcan anywhere, none of the remaining airframes are capable of being restored to flight - not to mention the costs or timescales. It took more than ten years to restore her (and several millon £££s)
Dunno, the advent of SAMs more or less finished the heavy bomber mindset, the Vulcan was moved from high altitude bombing to low level strikes in an attempt to protect the aircraft and crew, at least en route to the target. despite this though, the attrition rates would have been mind-boggling had they needed to be deployed in the ETO
Amen to that my friend.
