ONE man has died and another has been injured after two vehicles crashed on the runway at Heathrow Airport.
Emergency services said they were called to a "serious accident" at Terminal 5 at around 6am this morning.
One man, a member of staff in his 40s, went into cardiac arrest when his vehicle crashed into another Heathrow worker's vehicle.
Paramedics battled to resuscitate him both on the tarmac and en route to a London hospital.
But the Metropolitan Police confirmed at around 11am that he had not survived.
The second man involved in the incident was treated for a shoulder injury which has been described as "non-life threatening".
Both men had to be freed from the wreckage of the two vehicles by firefighters.

According to The Sun, passengers on a nearby plane saw "blue lights everywhere" as emergency service vehicles rushed to the scene.
Serious delays of up to several hours were caused to at least 25 departing flights but Heathrow's two runways remain open.
The Met Police said no arrests had been made.
"We were called at 6.06am on Wednesday following a collision between two airport vehicles on the taxiway at Heathrow Airport," a Met spokeswoman said.
"Officers attended with London Ambulance Service colleagues.
"One male was treated for non-life threatening or life-changing injuries. Another male, aged in his 40s, was taken to a west London hospital but later died.
"There have been no arrests. The Health and Safety Executive has been informed."
A British Airways spokesman added: "We have apologised to customers for the delay to a small number of our flights this morning, following an incident involving two operational vehicles at the airport.
"We are doing all we can to ensure they will be able to depart as soon as possible."
