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.

Investigators looking into the doomed Air India flight that killed 217 people when it crashed say the movement of vital fuel switches could be the key factor that led to the disaster, according to their preliminary reports.

The London-bound flight crashed shortly after takeoff, descending rapidly from 650 feet and killing 241 of the 242 people on board, along with casualties on the ground.
