Aerobytes put in cash for Farnborough display and some other events but the aircraft went tech after Farnborough they have first hand experience.
But like you say, things have/are changing up there so it might be worth testing the water.
You need to speak to Michael Trotter at VTTS who would welcome a call and a chance to talk (no hard selling).
I would hope they would have a new rate card for 2009 taking into account current times.
*******The rumour at Farnborough is departure Tuesday lunch time. If I get any info I will post it. COULD BE 558's LAST FLIGHT?**************
