And another man is in hospital after surviving the fall.

The two are believed to have clung on to a British Airways plane as it flew almost 13,000 kilometres from Johannesburg in South Africa to London's Heathrow Airport.

The victim fell on to a shop in Richmond, south west London, which is below the flight path, yesterday morning.

"A post-mortem examination will be held in due course and

inquiries are ongoing to establish the male's identity. No arrests have been made," said a Scotland Yard spokesman.

"The surviving man, aged believed to be between 25 to 30, has been taken to a west London hospital and currently remains in a serious condition."
