There are flight delays and cancellations at Heathrow airport today as the investigation continues into the crash landing of a British Airways (BA) jet yesterday.
BA has cancelled 12 flights, and there were long queues at Heathrow's Terminal 1.
The Air Accidents Investigation Branch (AAIB) will tomorrow give the first indication of what might have happened to the Boeing 777.
The Boeing aircraft just cleared a fence by a busy perimeter road before skidding across the grass short of the runway and pulling up around 1,000 metres from a plane about to take Prime Minister Gordon Brown to Beijing.
Mr Brown was among those who praised BA's captain Peter Burkill, whose actions limited casualties among the 136 passengers to just 18 minor injuries despite extensive damage to the plane, which had flown in from Beijing.
Arriving later in the Chinese capital, Mr Brown said: "I think it's right to pay tribute to the calmness and professionalism of the British Airways staff and the captain and what he achieved in landing the aircraft."
