Returning from a 3-week detatchment at Norfolk Naval base about 1968, we stopped to refuel in Lajes, which has miles of gleaming white sun baked concrete. The airman replenishing the oil left the hose running to attend another job, and yes, forgot about it! Soon, our scruffy old Shack was sitting in an expanding lake of oil contrasting well with the gleaming apron and immaculate US aircraft. The Yank reaction was almost a nuc attack on the UK, just shows how little sense of humour they have!
