Two commercial airliners on approach to New Jersey's Newark Liberty International Airport were illuminated by lasers, the Federal Aviation Administration said Friday.
A privately operated helicopter was also targeted during the same period, between 9:20 and 10 p.m. Thursday.
No injuries were reported.
It's a federal crime to aim a laser at an aircraft. High-powered lasers can incapacitate pilots.
The FAA said the helicopter was illuminated with a green and white laser at 1,600 feet, about 10 miles south of Newark.
About a half-hour later, a Boeing 737 and an Embraer 135 were targeted with a green laser on final approach to the airport. They were at an altitude of 3,000 feet, one mile east of Teterboro Airport.
More than 2,200 laser incidents were reported nationally through Aug. 2, including 27 in New Jersey and eight in Newark.
