Ten days after Air India flight AI2379 suddenly dropped more than 600 feet, injuring passengers and crew, a crucial question remains unanswered: what caused the A320 to lose effective flight control for around four seconds? NDTV’s exclusive reporting has revealed that all three hydraulic systems appeared to fail almost simultaneously before recovering moments later. Investigators are examining possible system, electrical, maintenance and pilot-related factors. Amid reports of the captain’s toxicology result, questions are also being raised over whether selective leaks are fuelling speculation before the investigation establishes what actually happened. Was this a rare systems failure, a cockpit-related event-or something else?
