JWR,
On Tuesday, President Obama made a hop into Seattle. A 30 mile “no fly zone” was established. A small float plane owner did not read the daily Notices to Airmen (NOTAMs) and flew into the zone by visual flight rules (VFR). This caused the Secret Service to have NORAD scramble two F-15s from the local [Air National Guard] air interceptor group based at Portland International Airport. Naturally, they requested and got clearance to go supersonic. This resulted in at least two sonic booms being generated. What happened next was, well, interesting:

It’s also believed that all of the cell phone level calling disrupted service in some areas due to overloading, all due to just two sonic booms. God help us if a real world emergency were to occur and the sheeple flood the cell and land phone lines. – MP in Seattle
