Story highlights London police seek public's help in finding operator of drone that may have struck airliner

No one was hurt and the plane wasn't damaged, but authorities worry about potential for catastrophe

London (CNN) Did a drone hit an airliner trying to land at London's Heathrow Airport?

The pilot of a British Airways flight certainly thinks so, and now authorities would like to find out who might have been behind the weekend incident.

British Airways Flight BA727 from Geneva was approaching Heathrow on Sunday afternoon when what the pilot believed to be a drone struck the front of the aircraft, London Metropolitan Police said. The plane was 1,700 feet in the air at the time, police said.

The Airbus A320 landed safely, with none of the 132 passengers and five crew members on board injured, British Airways spokesman Michael Johnson said.

The plane was fine, too, he said.
