Yes - but don't forget that even in the late 70s there were 4 Vulcan sqns of 10 x 5 man crews each at Waddo and 2 x strike and 1 x boat-spotting sqn at Scampton, plus the Vulcan OCU. That made around 350 Vulcan aircrew at any one time, plus loads of others who had already done their V-bomber time....
And we had around 70 Vulcans to play with! But nowadays the RAF can't even afford to buy its own basic training aircraft and has to rent the Tupperware Trainer (Das Teutor) from some civvie firm.......
Why the hell did we bother? Succesive governments have hacked away at the RAF's capability with barely a murmur from Their Airships.... Bar one - and he was 'invited to resign', I gather.
