Twelve different flight crews reported that someone was shining a laser into their cockpits as the aircraft were making their final approach Sunday evening at Seattle-Tacoma International Airport.

Pilots reported seeing the laser between 7:10 and 7:30 p.m. as they came in for landing, said Mike Fergus, a spokesman for the Federal Aviation Administration’s Northwest Mountain Region, headquartered in Renton. All of the planes were at an altitude of 1,200 to 1,500 feet and one of the pilots “had a fairly decent description of where the source was,” Fergus said. No suspects were found and all of the planes landed safely.

The FBI and Transportation Security Administration are investigating.

Shining a laser at an airplane is a federal offense.
