Many years ago, in the days of the white Valiant (543 Sqn, RAF Wyton), the great unwashed were threatening a break in, flush with their success at Fylingdales.
The airmen were given a pick axe handle each and told "None Shall Pass", but they weren't to touch any of the "peaceful" protesters. One young man was v v pi**ed off at being made to wander about on a lovely summer's day (it was a Sunday). One of the yobs, accompanied by the local press, climbed the fence and shouted to the airman that he wanted to come in. The airman told him to f*** off!
The next day the local paper reported that after a request for admittance, an RAF spokesman said that it was not possible!
