AHMEDABAD – In the wake of the devastating Air India plane crash in Ahmedabad, U.S. aviation safety officials have joined the ongoing investigation into the disaster that claimed at least 271 lives.

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.

Air India and the Indian government were looking at issues linked to its engine thrust, flaps, and why the landing gear remained open as the plane took off and then came down.
