The London-bound Boeing 787 struck a medical college hostel in a residential area of Ahmedabad minutes after takeoff Thursday, killing 241 people on board and at least 29 on the ground. One passenger survived.

As the investigation continued Friday into the horrific Air India Boeing 787 Dreamliner crash that killed at least 290 people, the sole survivor is doing well but is "psychologically disturbed."
