Just booked my ticket for this year, Sunday 9th June. At £30 it may sound expensive, but I can assure you, after attending last year, it is well worth the money!
Just posting this in case anyone else would like to join me. Cosford is the RAFs only airshow, and is near Telford, and ten miles north of me in Bridgnorth. If anyone wants to stay at mine the night before or after, that is no problem at all. Just let me know, as its first come first served
Alternatively there are some nice B&Bs nearby.
One last thing, you need to pre book your ticket for Cosford online.
