Doesn't have to be hosted as such MJ, we've had two already, one at Sherburn and the other at Leicester. Other than letting the airfield know that half a dozen a/c would be turning up and fuel requirements etc there's not a lot else to be done.
I'm happy to do Breighton by the way but do they open the sheds on a normal Sat/Sun? For first timers it's quite an impressive walk round.
