Sadly, similar incidents have occurred a number of times in the last few years.
In 2015 a stowaway fell from a British Airways aircraft and landed on the roof of a building in Richmond, west London.
He was discovered a short while after another man was found alive, but in a critical condition, in the undercarriage bay of an aircraft at Heathrow.

In September 2012 another poor soul fell in similar circumstances into a street in East Sheen a couple of miles from the Richmond incident.
