A British Airways holiday flight has made an emergency landing at Heathrow after an incident.
The flight BA866 was on its way from London to Hungarian capital Budapest when it suddenly turned around.
It had left Heathrow shortly after 7am and was cruising at about 18,684ft above Kent when something happened.
Just before reaching the English Channel, the Airbus A319 jet sent an emergency alert to air traffic control known as squawk code 7700.

Flight radar data shows how the passenger plane then began heading back towards Heathrow before landing at about 8am shortly after the emergency message.
It is not yet known what happened on board the Airbus A319 aircraft.
Squawk code in the aviation industry means general emergency.
The crew sent the 7700 code, flight data shows.
It gives the pilot the responsibility to do anything they need to to ensure safety onboard, regardless of the rules, Flightradar24 reports.
We approached British Airways for a comment.
The BA travel status shows the plane was scheduled to leave at 7.25am, but it has now been delayed to depart at 10.50am.
