Don't look on the Keypublishing forum then... there are a number of people in the aircraft restoration world who are currently muffed at the growing division within the BBMF between the "glorious flyboys" and the "mere ground-crew".
One of the groundcrew who has long been an excellent and well-regarded "people interface" with the public was kept off this year's Duxford "greeters" list, and some of the fliers actually told questioners at the show that those guys were "just ground crew, you don't want to talk to them".
The unit is like anywhere else, some good, some bad. I never experienced
any bad vibes with the groundcrew during my time there.
You have to bear in mind that all the aircrew, bar the boss, are part time volunteers (great hobby!) and not only give up their spare time (no argument there - it was an honour) but have to balance ever more demanding full time jobs with life on the flight. It is quite tricky arranging an afternoon off for 'a jolly' at BBMF, for the ac to go u/s and then 'be available' the next day - imagine your boss's response to a request for 2 afternoons off next week.
And I can't think of any current aircrew flight member who would actually say comments like those above, other than in jest (which apparently is ok, as evidenced by the support for a recent public comedic Telegraph report).
