I had a good sighting in the 60s, was in the afternoon after school, where a friend and I saw a bright point high in the sky, going in a straight line and followed by a fighter jet with contrail (F100 from Spokane?), when the bright point suddenly made a 90 degree zero radius turn and pulled away from the jet like nobody's business.
My Dad saw UFO over Korea while flying mission in 1951, he was a fighter pilot and certainly knew the state of aircraft technology and was known or unknown or within the bounds of known technology
To avoid being interrogated or grounded, he never told anyone except my Mom, who waited 50 years to tell me
Speaking of Spokane, in 1979 I was in Post Falls and watched a “craft” moving west about 500’ off the ground and about a 1/4 mile away moving west towards Spokane at a ground speed of 50 +/- mph (slower than the highway traffic). It was a quiet December winter night between 8pm and 9pm with snow on the ground which made it lighter than normal. No lights visible on the “craft”. What caught my attention was a low pitch hum. No wings, oval shaped and dimentions relative to a 747 as far as length to width ratio. I’ve always wished I had a camera.
