Going back a few years, it always puzzled me but before I became a fixture here, I visited as an ATC cadet during an air show about 1966, and I remember near the Comet tanks on the south side close to ETPS, there was a fuselage of something which wasn't a Comet. From later photos, I would have guessed it was an Ashton or (possibly) Apollo. It wasn't here by the time I started work here in '74.
