Now I think this is a funny story, told to me by one of the protagonists.
Years ago, a Bucc nav went on exchange to Aus on F-111s.
Later, a Bucc pilot did too (not at the same time). Both went to the Tornado on return to UK.
Years later, the plate F111BUC came onto the market.
Unbeknown to each other at that stage, both bidded in an auction, and the price went up...and up!!
One bought it - you might see it on a flash car around East Anglia.
