GD,
Paul (Bowen) & Tim (Prince) are the Directors of RIAT - I'm sure they'd be able to address some of your concerns, but also give an appreciation of the sheer scale and difficulty of putting on what is the Worlds Biggest Military Airshow (with 100,000 members of the public thrown in each day for good measure).
It is a huge feat of organisation, and, bear in mind, a large no. of the volunteers are just that - they are not paid for taking (up to 2 weeks in a lot of cases) away from their day jobs to make it happen.
Don't know which day you went, but it was heaving with people yesterday (Sunday)
Pilotwolf,
Yes, it's expensive, but has to be so that the Charities actually get something out of it at the end.
Some of those kids may be the Aircrew of tomorrow. Mine loved it!
Cheers
