The military called its response to Air Force One successful after a private plane violated restricted airspace.
A couple in a small Cessna flew close to the president's plane near Seattle. The military scrambled two F-15 fighter jets from Portland, Ore. to intercept the Cessna.
The fast flying caused sonic booms. People called 911 when the sound rattled the ground below.
The couple in the Cessna didn't know they did anything wrong until Secret Service agents met them when they landed. "We just landed, sailed in here, nice and peaceful, pulled up to the dock, and a guy came out and said, 'I have some bad news for you guys'," said passenger Laura Joseph.
Authorities said the Cessna's pilot was supposed to check for listed restricted airspaces before flying.
Oregon’s Air National Guard said it has aircraft ready to respond to situations like this one 365 days a year.
