Sigh. KOMO 4 News:  F-15s responding to air space breach trigger sonic booms

SEATTLE -- Two F-15 fighter jets rushing from Portland triggered two sonic booms that were heard across a wide swath of the Puget Sound region, fraying nerves and knocking out 911 service to parts of Pierce County for about an hour.
The jets were responding to a float plane that had entered restricted presidential air space over Western Washington, the FAA reported.

Didn't hear the boom in the Salt Mines, but evidently my co-workers and I are about the only folks in western Washington who didn't.

Mrs. Drang said she was a bit puzzled at first, as all she could see was a float plane coming inn for a landing...
