Air India flight AI171 took off from Ahmedabad airport on the afternoon of 12 June with 242 people on board. Less than a minute later, it had crashed into a medical college about 1km away.
Including those on the ground, at least 270 people were killed. But one passenger miraculously survived. Vishwash Kumar Ramesh, a British national sat in seat 11A, was able to walk away from the scene – though, as he found out soon after, his brother had died on board.
The aviation journalist Jeff Wise explains what investigators will be looking at to determine the cause the crash – from the plane’s landing gear, to its wing flaps and possible pilot error. Helen Pidd asks how it was possible that Ramesh was able to escape with his life.
