On July 4, 1947, at early twilight, I was walking in Woodland Park in Seattle, WA, near the University of Washington.
I was a 22 year old student at the time.
The park overlooked Puget Sound and the Olympic Mountain Range to the West.
I happened to look up and saw a bright, oval shaped object coming down from the upper atmosphere.
There was no sound of motors, the object had no wings.
The object made a very sharp almost 90-degree turn to the horizontal and then sped South along Puget Sound at high speed and towards Mt. St. Helens.
I was very surprised.
At about the same time on July 4, 1947, a Seattle bus driver and U.S. Navy member saw similar objects over Seattle.
On June 24, 1947, a light plane pilot and a prospector saw 9 silvery flying saucers flying in line at high speed from North to South over nearby Mount Rainier and Mount Adams, WA.
On July 4, 1947, 2 airline pilots and a stewardess saw similar 9 flying saucers flying from southeast to northwest from Boise, ID, towards Mount Rainier and Seattle.
