The deadly Air India crash last month has renewed a decades-old debate in the aviation industry over installing video cameras monitoring airline pilot actions to complement the cockpit voice and flight data recorders already used by accident investigators.

The investigation report says Air India did not carry out those inspections - prompting speculation that the accident could have been caused by faulty switches being flipped by accident. However, in an internal note seen by the BBC, the FAA has since reiterated its belief that the issue did not compromise safety.

THE deadly Air India crash may have been the result of a human act inside the cockpit, a top aviation expert has warned. Captain Steve Scheibner suggested there was a “human hand”

The CEO of Air India sought to draw a line under rife speculation around the cause of last month's air disaster in Ahmedebad, saying the preliminary investigation had ruled out a mechanical cause for the crash.

The flight, a Boeing 787 Dreamliner, crashed just seconds after take-off from Ahmedabad in June, killing all but one of the 242 people on board.
