The amount, and quality of information available now is just fantastic.
When I was researching for an R/C build quite a few years ago, a lot of this was unobtainable.
When I was at Westlands there was some activity from the enthusiasts at a nearby Test & Evaluation Establishment looking to dig a corner of the airfield (the old fire training pan if memory serves), where it was thought the remains of G-AGOI had been bulldozed under when the new Social Club was built.
I think Wessex Archaeology/Time Team were approached at one point, but the Westlands Archivist, the Late Fred Ballam, found some aerial photos of the site from around the time construction started, and it confirmed that the site had been cleared, so that saved a lot of trowel work!
