The cockpit voice recording of Air India Flight 171, which crashed recently, indicates that the plane's fuel supply was manually cut off before the accident. According to reports from the Wall Street Journal and other sources, the younger co-pilot questioned the more experienced captain about why the fuel-supply switches were turned off. The captain denied having cut the fuel supply. This exchange was captured in the audio recording but the specific speaker who turned off the fuel switch has not been definitively identified. Aviation experts and senior Air India commanders have discussed the incident, with some suggesting the possibility that the pilot may have intentionally cut the fuel, though the motive remains unclear. The incident has drawn attention to the operation of the Boeing 787 Dreamliner's fuel system and its role in the crash. Additional details include the last communication from the pilots, which involved a dispute over who cut off the fuel. The investigation is ongoing, with various aviation safety experts analyzing the cockpit recordings and circumstances surrounding the crash.
