Wrong Place, Right Time
In 1969 I was Viet Nam, posted as a mechanic with an assault helicopter company. I was at the time a technical inspector. My job was to verify that scheduled maintenance tasks on helicopters were properly done before the ship went on its’s next mission.
One evening I was called from my tent to the flightline do make that check and sign off on the work and while I was on top of the ship, a Viet Cong rocket flew overhead. It hit the tent I had just left, killing my roommate. Story credit: Reddit / tallenlo
