Reports say a suspected stowaway from Kenya Airways is believed to have fallen from the landing gear of the plane that was preparing to land into Heathrow Airport and has been found dead in a London garden.

The body, believed to be that of a man, was found in a London neighbourhood known as Clapham on Sunday.

A resident in the area said the man fell about a metre away from another resident who was sunbathing.

“I heard a whomp from my apartment and when I looked out of my window I saw the body and blood all over the walls of the garden. So I went outside, and it was just then the neighbour came out and was very shaken,” said the resident who did not want to be named.

The neighbour, who also asked to remain anonymous, said a plane spotter, who had been following the flight on a plane tracking application on his mobile phone from Clapham Common, had seen the body fall and noticed it had fallen from a Kenya Airways flight.

“If it had been two seconds later, the man would have landed on the Common, where there were hundreds of people. I spoke to Heathrow Airport about the situation and they said this happens once every five years,” the neighbour added.

“One of the reasons why his body was so intact was because his body was an ice block,” he said, describing the victim.

British police said a post-mortem examination will be carried out in due course and that the death was not being treated as suspicious.

Kenya Airways said the aircraft was inspected and no damage was reported, however airline officials found a bag, water and food in the landing gear compartment on the aircraft.

“The 6 840km journey takes eight hours and 50 minutes. It is unfortunate that a person has lost his life by stowing aboard one of our aircraft and Kenya Airways is working closely with relevant authorities in Nairobi and London as they fully investigate this case. We would like to express our condolences,” said a spokesperson for the airline.

This is not the first death of this kind on the Heathrow flight path as one man was found dead on the roof a popular British website’s headquarters in Richmond.
