That's how long Air India Flight 171 was airborne before it plunged into a densely populated neighbourhood in Ahmedabad in one of India's rarest aviation disasters in recent memory.Investigators now face the grim task of sifting through the wreckage and decoding the cockpit voice and flight data recorders of the Boeing 787 Dreamliner to piece together what went catastrophically wrong in the seconds after take-off.

Air India plane crash investigators have found both of the Boeing 787's "black boxes," hopefully brining an understanding of the disaster a step closer.
