The newly released crash report into Air India Flight 171 reveals the heart breaking sequence of events that unfolded on board. What began as a routine journey tragically spiralled into disaster — not due to mechanical failure or weather, but as a result of what appears to be a manual shut-off of fuel supply to the aircraft’s engines by one of the pilots or an unknown issue with the Boeing 787.

In the wake of this revelation, we’ve broken down the key moments from the flight to help readers understand exactly what happened, and when.
