They already try to charge a load of money to get in,incidentally the arranged tour only lets you into the one hangar deemed safe enough for the general public,on the plus side this is the one with most of the aircraft in but sadly not the comet or trident.
It does have N7777G a rarther beautiful connie in it though.
Even though i have done nothing but gripe about Wroughton i have no axe to grind with the Science museum they are afterall preserving our heritage i just find it hard to accept this fantastic collection is hidden away.
