The black box from the Air India plane that crashed in Ahmedabad has been found. Many people died in the crash. The black box can help us understand why the plane crashed. The plane was flying to London. It hit a building after it left the ground. The black box will show how the engine worked and what the pilots said. This might tell us if the engine lost power or if the plane could not go up. The only person who lived said the plane had problems right after it took off and could not get high enough. People investigating will check the wings, engine power, and alarms. They will also check information about the outside temperature, fuel, and how heavy the plane was. Groups from the U.S. will help with the investigation to stop similar accidents from happening again.
