If it`s going to be a mainly RAF line up military wise, then perhaps it would be an idea to request some of the less often seen RAF types, even just for a few passes if a display is not feasible.
Things like the A400M, Poseidon MRA 1, the RC-135W Rivet Joint, the Texan T1 and of course the F-35.
Also ask the USAF and USN if they have anything they could divert for a few passes to / or from Europe, such as a C-5M, or some F-15`s to make some noise.
I really hope it`s not going to be the same stuff yet again, otherwise there isn`t much point in going. Everyone wants to see new displays and a range of types, not just the airshow regulars.
