Ah, the hole-in-the-ground story again. Has anyone actually ever found one of these fabled dumps on any former US airfield? I'd read that one at Stansted had been raided, but the diggers swore to keep mum about what they'd found.
Just read a nice story about how US servicemen from Bovingdon turned out in force to help at the site of a nasty train crash at nearby Bourne End in September 1945.
Apparently, a USAAF pilot spotted the incident just after t/o and alerted the tower.
