I had my window open and heard such a loud boom I could feel it. I went back and watched surveillance video to find there was a flash 20 seconds before the boom. Tons of other people in Redmond very wide spread also heard it and some saw the flash in the sky.

Remarks
There was a flash from the south that reflected onto someones garage door which is in my north. Did not actually see anything in the sky, just the reflection of the flash coming from the south.
