The left engine of the BA aircraft that caught fire on the runway at Las Vegas airport had "multiple breaches of the engine case", US air investigators have found.
157 passengers and 13 crew were forced to evacuate the plane.
Aviation experts have been alarmed at images of passengers clutching their hand baggage as they were evacuated from the burning British Airways plane in Las Vegas.
A number of travellers stopped to get their suitcases, rucksacks and other bags from under their seats and in the overhead lockers before leaving the plane via the emergency chutes.
Aviation expert Julian Bray described the Las Vegas incident as a "textbook emergency evacuation" apart from passengers taking their bags with them.
Captain Brendan O'Neal, chairman of the British Airline Pilots' Association, said: "Failing to follow the instructions of the crew by stopping to collect luggage is extremely dangerous as it slows down the evacuation, could block aisles and prevent passengers getting off in time and could cause injuries."
Steve Bingham suffers regular flashbacks and been on medication for psychological trauma since the incident.
The veteran British Airways pilot hailed a hero for saving the lives of passengers on a burning plane has said he is unlikely to fly again.
