My wife’s cousin was a Blackbird driver.
I knew a guy who claimed to be a blackbird driver but he flunked 2 basic qualifying questions.
I asked him how much overlap was involved in ‘mowing the lawn’. He was unfamiliar with that expression.
I asked him if it was true that the fuel tanks would leak while still on the ground, not sealing up until the heat expanded them together at a certain [classified] airspeed. He got that answer wrong.
He was fulla Bullshiite.
