A Virgin Atlantic flight was forced to return to Heathrow after one its pilots reported being dazzled by a laser outside London.
The Airbus A340 was a few minutes into its journey to New York's JFK airport when it reported the incident. However it continued on across Ireland before deciding to return.
A recording of one of the pilots of flight VS025 requesting permission to return was published online.
He used the code "pan, pan, pan" to alert air traffic control to an onboard emergency that does not pose a threat to life.
"We have a medical issue with one of the pilots after a laser incident after take off and we are going to return to Heathrow," says the pilot.
