I was at RAF Colerne in the mid-sixties and started the Museum there that was broken up when the Station closed. I heard many stories about aircraft that had been based on the Station,especially the brand new Avro Lincolns that were delivered from the factory, air tested and then taken to the North end of the short runway to be broken up for scrap.
I spent hours talking to the locals and never heard one word about any aircraft that were buried there. Had I done so I would have been the first to borrow a JCB and start looking. Just remember, in the sixties we still had a lot of locals working on the base who could remember the war and would have known about such a thing.
I heard rumours of Sptifires still being in the hangars at Charmy Down (not true) and another that there was a Hurricane and a Mosquito in one of the hangars at Hullavington (absolutely true).
But that is another story!
