Two sonic booms rocked the southern King County area shortly before 2 p.m. The Seattle Times is reporting the sonic booms were caused by two F-15 fighter jets that were launched after an airplane flew into restricted airspace around Boeing Field.
The Jets were scrambled from the 142nd Oregon Air National Guard Wing in Portland.
So many calls were made to 911 in Pierce County that it shut down the call service for a time, Detective Ed Troyer, spokesman for the Pierce County Sheriff's Office said.
President Obama is in Seattle this afternoon hosting a fundraiser for Democratic Sen. Patty Murray. Air Force One landed at Boeing Field earlier this morning.
