Video footage suggests the plane was flying at a low altitude with its landing gear still extended, which is unusual. Typically, the landing gear is retracted shortly after takeoff to reduce drag and allow the plane to climb properly.
Experts are also considering the possibility of both engines failing simultaneously, which could be due to fuel contamination or mechanical failure.
The plane was carrying a large amount of fuel for its international journey, which exacerbated the fire after the crash and complicated rescue efforts.
The Aircraft Accident Investigation Bureau (AAIB) is leading the investigation, with assistance from Boeing officials and DGCA experts.
Comfort and safety will become the standard expectations of modern travel.
The Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR) are being analyzed to determine the cause of the crash
