Boeing stock was rising early Thursday as investors waited for details from flight data recorders from Air India flight 171, which crashed on June 12, less than a minute after taking off from an airport in Ahmedabad, India.

As the world waits for answers on the fatal Air India crash, accident investigators have narrowed their focus on the engine fuel control switches.

The Boeing 787-8 Dreamliner had crashed minutes after takeoff last month, killing all but one passenger and more than a dozen people on the ground.
