A pilot coming in for a landing at Lindbergh Field reported seeing a laser near the flight path Monday night.
As United Flight 691 was on its final approach, the pilot saw the laser at 8:15 p.m., according to airport spokesman Jonathan Heller.
The plane landed safely, and no injuries were reported.
The apparent laser strike came from 32nd Street near Naval Base San Diego, San Diego police said, quoting a Harbor police radio advisory.
Harbor police officials are deferring all questions to the airport.
It comes about two weeks after another pilot landing at Lindbergh Field reported seeing a laser light in the cockpit.
Pointing a laser at a commercial airliner is a federal offense. It's punishable by up to 20 years in prison and an $11,000 fine, according to the FBI.
