British Airways flight from Heathrow declares general emergency
The flight left the airport at 3.27pm, over an hour after its scheduled departure time of 2.15pm.
However, it has now declared a "general emergency" and remains in airspace over the English Channel, possibly to return to the airport.
According to live flight tracker, Flightradar24, the plane made it halfway across the channel to France before turning back, at which point it began circling over the water.
It was due to arrive in Bengaluru in India in approximately nine hours.
British Airways has commented further to confirm that the flight "landed as normal" and that the incident was a "priority landing request". ■
