bill2b, "the poor bloke in the old RAFP uniform must have been roasting" was my younger brother who is now the groundsman at NAM. In a previous life he spent 22 years as an RAF Policeman and is now active on the re-enactment scene.
The Museum were not expecting anything like the numbers of people that actually turned up for the Vulcan display. I suspect, looking at various reports on the Interweb, that it was much the same at all the venues 558 visited yesterday. Have seen some great photos and video footage on several sites particularly Twitter.
The buckets you saw were to collect funds for projects at the Museum and the VTS. See the link:
