I know the photo you mean and you can find a copy on the Vulcans In Camera site. In my time they came over from their quarters at the Ops Block in bog standard Crew Busses, one for each crew. I never saw a Vulcan crew wearing hats on a QRA alert either.
We'd dash 'two-six' out of our grotty old caravans right next to the dispersals (which weren't the ORPs on the end of the runway that were used for demo scrambles) at the sound of the hooter and get our allotted bomber alive and kicking. It wasn't that much of a rush for them 'cos we'd be busy getting power on and removing the bungs and blanks, while the crews took a more leisurely drive from their luxurious accommodation. As befitting poor folks who might be leaving on a suicide mission.
Of course, being firmly rooted at a primary target bomber base, we'd have been painlessly vapourised ourselves, long before they crossed the Norwegian coast...
