My wife was at the Costco in Tukwila when it happened. She described it to me and I said that, as stupid as it sounds, she was describing a sonic boom. Which it was.
In the early 60’s I heard (and felt) them all the time. I was in grade school and thought they were incredibly cool and a symbol of our nation’s power.
I loved the sonic booms when I was a kid. I love it when the Air Show is in town and we may get a few booms from the Blue Angels, that is until some libtard complains. Obamass said the sweetest sound was the muslim call to prayer....I say it is the magnificent sound of US fighter jets overhead going through their manuevers!
