the vulcan
will be on a permit to fly
can't imagine the CAA saying that aircraft has to bimble around at 1500ft VFR with all the cessnas and PA-28s in the Barkway to Brookmans PK gap in between Luton and Stanstead when it goes to Biggin for the 2008 airshow....
I think CAA will eventually allow some aircraft to operate IFR
But don't hold your breaths
