Does Bisto need permission?
I have no idea, but a connection with Bomber Command would help, and that means something much more than:
Although not used for active service Bicester retains:“… better than any other military airbase in Britain, the layout and fabric relating to pre-1930s military aviation…..
.... it comprises the best-preserved bomber airfield dating
from the period up to 1945…… It also comprises the best preserved and most
strongly representative of the bomber stations built as part of Sir Hugh
Trenchard’s 1920s Home Defence Expansion Scheme”. (English Heritage).
Says who? ......... "most strongly representative". With a grass strip.
