Richard Taylor, from the Civil Aviation Authority, said this kind of incident was not the first of its kind and added that there was very little chance of survival for stowaways.
He said: ‘The temperatures in the undercarriage reach -40C (-40F) at high altitudes, so the person has basically frozen to death. There is virtually no chance of someone surviving that.'
‘It is a very dangerous environment. Very often people get crushed to death by the landing gear when it retracts.
'It is surprising that people still do it. I guess they don't realise they have very little chance of surviving.'
