DALLAS (AP) _ A green laser struck two small planes overnight in Dallas, raising safety concerns in an incident that can be prosecuted as a federal crime.

The Federal Aviation Administration reported Sunday that two pilots reported seeing the laser shortly after midnight.

The planes were heading to Arlington and were about 12 miles south of Dallas Love Field airport when the incident occurred. They were at about 3,000 feet.

Laser lights can obstruct the vision of a pilot, and unauthorized use of a laser is a federal crime.

A Dallas man got 2 1/2 years in prison in 2013 after using a laser pointer in the direction of a police helicopter.
