NEWARK, N.J., Dec. 31 (UPI) -- The FBI is investigating laser beams shined into the cockpits of seven aircraft as they were about to land, the New York Times (NYSE:NYT) said Friday.

The latest incident occurred Wednesday when a laser beam hit the cockpit of a Cessna Citation as it approached Teterboro Airport, near Hackensack, N.J., about 12 miles from Manhattan, officials said.

"All of a sudden the pilot saw his cockpit being illuminated by a laser," said FBI spokesman Stephen Kodak. "The light was flashing on and off. It went on for about 20 seconds."

None of the incidents have resulted in crash landings, but pilots reported momentary disorientation. The FBI wants to determine if the incidents are terror-related.

Other incidents have been reported during landings at airports in Houston, Washington, Cleveland, Colorado Springs and Medford, Ore.
