Sonic Boom in Seattle: Cessna 180 Plane Violated Airspace Restrictions – A lot of tweets surfaced Thursday about a great sound that shook some of the apartments and buildings in Seattle. Some thought that it was an earthquake. Others said that it was like a giant stomping his feet on the ground. However, upon further inquiries, it was found out that the sound came from two sonic booms.
A sonic boom is the sound associated with the shock waves created by supersonic flight of an aircraft when it exceeded the speed of sound generating huge amounts of sound energy, sounding much like an explosion.
According to Federal Aviation Administration (FAA), the sonic boom that occurred around 2pm Thursday came from two military fighter jets dispatched from Portland after the pilot of a spotted aircraft violated presidential airspace restrictions in lieu of Obama’s visit to Seattle for a campaign fund raising event for Sen. Patty Murray.
It was then later confirmed that the sonic booms came from two F-15s, a twin-engine, all-weather tactical fighter aircraft designed to gain and maintain air superiority in aerial combat. The North American Aerospace Defense Command providing aerospace warning to both US and Canada immediately dispatched the said fighter jets upon receiving reports of an airspace violation.
The subject of the violation was a Cessna 180 float plane which breached the presidential no-fly zone. Laura Joseph, a passenger of the Cessna 180 was puzzled after she saw an F-15 fighter plane calling their attention. She later found out about the airspace violation that she and her companion Daily committed.
The two sonic booms prompted various people to exit from their respective workplaces in nearby areas to inquire about the cause of the two window-shaking booms. Below is a picture of the Cessna 180 which breached the presidential airspace restrictions.
