According to a report published on Wednesday by The Wall Street Journal quoting sources close to United States officials’ early assessment of evidence, the black box audio recording of the last conversation between the two pilots indicates that the captain might have turned off the switches controlling the flow of fuel to the plane’s engines.

The preliminary report from the investigationg into last month's deadly Air India crash showed that seconds after takeoff, the Boeing 787 plane's engine fuel control switches were briefly flipped off.
