In 1969, I was departing Spokane International Airport in a NW Airlines Lockheed Electra at the runway threshold, when two Washington State ANG F-101's took the runway. After sitting a few seconds, they both throttled up and immediately hit afterburners, rattling the windows in the Electra. I suppose they had to know what they had done and were just having a little fun. While working a spring break job in Spokane, I also saw the 101's roaring down the canyon valley, apparently below canyon rim level at 400+ knots, so close I could see their little helmeted heads bobbing in the cockpit.
