A couple of points:
The organisation of the aircrew hosting is very much done despite the best efforts of the civilian contractor who has no real interest in anything except making money. They are trying to recover from a position about 3 years ago where there practically wasn't any aircrew hosting, and the guys at Yeovilton are fighting a losing battle to make the contractor understand the reality of an airshow versus some other "events" she may have run previously. Incidentally, contrary to what some others have posted, I understand that the feedback from aircrew has generally been positive - in some cases gushing!
As to the success of contracting out the Airshow organisation for 5 years and then supplying all the labour and work free of charge to the contractor... sounds like the normal MOD approach to life. Both barrels aimed at both feet. Particularly when they then charge for the officers' mess to put an enclosure on it's own airfield (which is why you have to pay to go in - the Wardroom has to recover it's costs somehow. Far more pertinent a question is why they ever went down the route of having a contractor in the first place: Why haven't they even got access to the contractor's accounts so they can work out whether it is a financial success or not?)
The final and most telling gripe has got to be the lack of involvement of other UK assets - where's the sense of team spirit, particularly when some VLN assets have been seen around the country for the whole display season (Lynx Pair for ex.)?
