BOSTON (AP) - Law enforcement officials are trying to determine who pointed a laser at a passenger jet heading toward Logan International Airport on Thanksgiving eve.

The Boston Herald reports the incident happened Wednesday when a Southwest Airlines pilot reported a green laser shining on the side of the Boeing 737 headed into Logan. The aircraft was 16 miles northwest of the airport at an altitude of 16,000 feet, according to the Federal Aviation Administration.

It’s the 40th time this year someone has trained a laser at an airplane in Massachusetts, tying last year’s number. The numbers are down from the 80 or more laser strikes in Massachusetts in 2017, 2016 and 2015.

Aviation officials warn pointing a laser at a plane is both a safety risk and a violation of federal law.
