The black box from the Air India plane that crashed in Ahmedabad, killing 241 people on board and others on the ground, has been found. This device could help explain why the accident happened. The Boeing 787, which was going to London, hit a medical college building soon after taking off. The recorder should show details about the engine, controls, and conversations in the cockpit. This might reveal if the plane lost power or couldn't gain height after takeoff. The only passenger who survived said the plane seemed to have problems right after takeoff and couldn't climb before it crashed. Investigators are probably checking things like the wing flap settings, engine power, cockpit alarms, and data about the outside temperature, fuel, and passenger weight. Experts from the NTSB, FAA, Boeing, and General Electric in the US will join the investigation to help prevent future accidents.
