My Sis just messaged me that she and my Nephew saw fighters overhead with an accompanying sonic boom heading North. Guess it was for intercepting a stolen Q400 from Sea-Tac airport that subsequently crashed. Pretty amazing. Don't know much more at this time.
Just saw one plane come in at 10:25... but nothing else. I live North of the airport near where all the planes coming in for a Southbound landing turn onto final right over me.
