Boeing investors finally have details from a preliminary accident report for Air India flight 171, which crashed on June 12 less than a minute after taking off from an airport in Ahmedabad, India.

While the Air India Boeing 787-8 crash inquiry has found that fuel control cut-off switches were activated almost as soon as the aircraft lifted off, the circumstances of the switches' movement remain unexplained.

The two engines on the Air India flight shut down within one second of each other before the Boeing 787 Dreamliner crashed last month in Ahmedabad, India, killing at least 260 people, according to a preliminary report released Friday.
