Overview

• The June 12 crash of the Air India Boeing 787 Dreamliner killed 270 people, including 29 on the ground, after the jet plunged shortly after departing Ahmedabad.
• Investigators suspect both GEnx engines stopped functioning nearly simultaneously after liftoff, a scenario experts say would have made recovery impossible at low altitude.
• Analysis of amateur video confirms the Ram Air Turbine deployed before the crash, indicating a full loss of both engine-driven electrical and hydraulic power.
• Simulator trials run with Boeing pilots showed that only dual-engine shutdown could recreate the rapid descent that led to impact.
• Teams from Boeing, GE Aerospace and the Aircraft Accident Investigation Bureau met June 16 as they await black box data to shed light on engine performance and cockpit communications.
