A couple of sonic booms shook Seattle this afternoon as fighter jets scrambled to intercept a plane that violated President Barack Obama‘s airspace restriction.

The jets were dispatched on Tuesday afternoon while Obama was visiting Seattle.

A passenger on board the plane says that the pilot, Lee Daily, had no idea they were doing anything wrong.

“Oh my God, I can’t believe – is this the top news thing?” passenger Laura Joseph told the Associated Press.

Because of Obama’s visit, the FAA had prohibited planes from traveling below 18,000 feet within 30 miles of Boeing Field.

The pair of F-15 Eagles hit supersonic speeds as they moved to intercept the plane, which landed uneventfully before the jets arrived on the scene.

The Secret Service met with Daily after he landed at the Kenmore Air marina on Lake Washington, which had been closed during the presidential visit.

Joseph says she saw the fighter jet out her window as the plane was on approach to Seattle.

“I saw a jet, just a white jet going by,” she said. “I thought it was kind of odd to see a military jet.”

Sonic booms were reported by residents as far south as Southwest Washington.  In some counties, 911 lines were so jammed with phone calls that they were over capacity.
