A preliminary report on the Air India flight AI171 crash in Ahmedabad, India, reveals that the fuel supply to both engines was cut off during ascent, causing the deadly crash that killed 261 people. The flight data recorder indicates the fuel switches were flipped to the 'cutoff' position within a second of each other, though it's unclear whether this was accidental or deliberate. While the report points to the fuel cutoff as the cause, it doesn't explain how the switches were flipped, leaving questions about pilot error, technical malfunction, or other possibilities. A full investigation is ongoing.
