The investigation into the tragic Air India Flight AI171 crash in Ahmedabad, which killed over 270 people, has sparked several theories. Experts suggest a rare dual engine failure, possibly due to fuel contamination or a bird strike, though the latter is less likely as the Boeing 787-8 is designed to fly on one engine. Improper flap settings and failure to retract landing gear are also under scrutiny, with CCTV footage showing the plane struggling to gain altitude. Some speculate sabotage, citing political tensions, but no evidence confirms this. Black box data is expected to provide clarity.
