It may seem fun and harmless, but it’s extremely dangerous as well as a federal offense. We’re talking about shining laser devices at aircraft, something that happened 12 times Sunday night Feb. 22nd near SeaTac Airport.

According to the FAA, light from a green laser “hit” numerous airplanes as they came in for landings. All aircraft were descending at an altitude between 1,200 and 1,500 feet, and one pilot could actually see where the source was coming from.

All the planes landed safely, and no suspects were apprehended. The FBI and TSA are investigating.

If you have any information about this serious offense, please contact Port of Seattle Police immediately at 206-431-3490.

From initial research, green laser pointers like the one used can be bought online from around $22 to $300.
