LJ I am sure that you are correct. RAF Northholt is also the longest continually used airfield in the history of the Royal Air Force.
'
Section 69 of the Civic Amenities Act 1967 gives local councils the power to designate as Conservation Areas, "areas of special architectural or historic interest, the character or appearance of which it is desirable to preserve or enhance". Designation gives control over the demolition of buildings and provides the basis for policies designed to preserve or enhance all the aspects of character or appearance that define an area's special interest.'
Failing this we could implement
Section 69 of the Royal Air Force Act for anyone who interfers with this historic airfield
