When and where did you first see a Boeing 747?

1500 built since 1968!
It’s first test flight was flown across the state of Washington at 10,000 ft., it turned around and flew back to Boeing Field.
In 1968, we lived in Moscow. Idaho. (elevation 2564 ft.) There are no major air fields around so the sound of a low flying jet gets your attention.
I had just walked out of the front of our house, heard a jet and looked up. There, about 8,000’ away, was the first 747, making the turn around on it’s first test flight.
The next time I saw one, I was in Denver, Colo., 1975, living in an apt. about 400 yards from a runway at the old airport. I was returning home late one night after a party when one went past the end of the alley while landing. Scared the crap out of me!
