I have a few, some just funny.
1. During a tour of Coningsby and on seeing a Phantom drop tank lying in the hangar I asked “how many GALLONS does that hold sir” to the senior officer in charge. I never lived that down.
2. During one presentation the speaker’s microphone died and he asked if we could hear him at the back of the room “yes we can” came the reply, about 2 minutes into his presentation the same voice called out “we can still hear you”. Fortunately that wasn’t me because the culprit paid dearly.
I learned at an early age that drinking in company with senior colleagues was a bad idea, I stopped doing it after one major gaffe at the age of 25 and lived by that rule for the next 30 years.
