Federal officials are investigating reports from two pilots who say bright lights were aimed from the ground into their cockpits as they headed into the Colorado Springs Airport.
Both planes landed without problems on Monday night.
Federal officials issued a warning this month that terrorists might try to down aircraft by shining powerful lasers into cockpits to blind pilots during landing approaches.
The pilots heading into Colorado Springs about 8-30 p-m Monday reported a bright, pulsating light shining into the cockpits. Colorado Springs police say the pilots described the lights as "green laser lights."
F-B-I spokeswoman Monique Kelso says authorities haven't determined what type of light was used, and F-B-I agents are conducting interviews.
