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.

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.

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