London: Reports of smoke coming out the rear of a plane caused chaos at London's Heathrow Airport and forced the authorities to shut down two runways on Friday.
A British Airways flight, on way to Oslo, was forced to make an emergency landing and all passengers were safely evacuated.
One of the two runways was opened later on and the aircraft took off from London safely. Authorities ruled out any terror link to the incident.
Reports of smoke coming out the rear of a plane caused chaos at London's Heathrow Airport but all passengers were evacuated safely.
"The BA762, Heathrow to Oslo service, returned back to Heathrow shortly after take-off due to a technical fault" said the British Airways in a statement. "The Airbus A319 aircraft was carrying 75 customers. The aircraft landed safely and emergency slides were deployed and we are currently caring for our customers," the statement added.
"Emergency services attended the aircraft. We will be carrying out a full investigation into the incident," it said. The southern runway has since re-opened but the northern runway, the scene of the incident, remains closed causing severe delays to flights in and out of one of the world's busiest airports this morning.
Some of the morning flights to India, including a London-Mumbai Jet Airways flight, were also facing "some delays," according to a spokesperson. Heathrow is the world's busiest two-runway airport with a flight taking off or landing every 45 seconds.
A number of flights were being diverted to other UK airports, such as Stansted, for re-fuelling as they awaited further news on take-off and landing procedures at Heathrow. Some short haul flights are likely to be cancelled.
"As you looked up you could just see the flames being chucked out of the engine. It was on full fire when we saw it," an eyewitness told Sky News in reference to the aircraft as it made its way to an emergency landing at Heathrow. London Fire Brigade crew have said they believe that the fire is now out.
One passenger, David Gallagher, a senior partner at Ketchum PR agency, described on the social networking site Twitter the dramatic moments the stricken plane made the emergency landing. Posting a picture of the grounded plane at 8:49 am BST he said, "This is what an emergency landing looks like. Great job getting us down and off the plane @British_Airways 762". Aviation experts have speculated a possible bird hit may have caused the accident.
