All but one of the 242 people on board the London-bound flight died when it crashed into a residential area shortly after take-off on Thursday - it is not yet known how many people on the ground were killed. 

The sole survivor, British national Vishwash Kumar Ramesh who sat in seat 11A, is recovering in hospital with his brother saying he "has no idea how he survived". 

According to Air India, there were 169 Indian nationals, 53 Britons, seven Portuguese nationals and one Canadian on the flight. 

Families have been giving DNA samples to help identify the victims as they desperately wait for their relatives' remains.
