Bovingdon
Went on a course to the States, in the 60's with my line boss (Bill?) who was once at Bovingdon with Skyways and lived at Hemel Hempstead.
Bill was later to be the line boss of Euravia, and then Britannia.
He recalled that when the Americans moved out of Bovingdon, a large deep hole was dug and filled with brand new snap on tools and covered over, to the dismay of English fitters who had to buy their own .
Was this true, or was it just aviation folklore, one will never know
