I’ll share one of someone else’s stories - Bee Beamont no less, may he Rest In Peace.
In his later years Bee was employed by BAC as a flight ops director when they received a complaint from a customer regarding faulty “fire control systems” on some new Strikemasters (edit - can anyone enlighten me as to what exactly a Strikemaster FCS consists of apart from an optical gunsight ?). Bee flew out in person and went on a training mission with the foreign customer’s chief instructor who he said was a rather abrasive character. The flight out to the range was carried out at ultra low level across open desert, and the altitude could have been measured with a yardstick, the Strikemaster was also running at full chat. Bee stated that the pilot had to lift alternate wings to avoid hitting the sand dunes which they were clearing by 2 or 3 feet at most, he went on to say that in spite of having been shot at in combat this single flight was the only time in his entire flying career that he was ever genuinely terrified.
