Hope you're booked into Kemble. It's the Great Vintage Flying Weekend and quote
"G-VFWE 2002
URGENT MESSAGE FOR PILOTS!
We regret that no further aircraft of any type can now be accepted for G-VFWE 2002.
Coming by air without a PPR No. will achieve nothing, as a TRA is being set up for the duration of the event.
We very much regret these last-minute restrictions, but pre-registration has been open since the start of 2002. Please try earlier next year!"
