(CNN)The pilots of Lion Air Flight 610 were engaged in a futile tug-of-war with the plane’s automatic systems in the minutes before it plunged into the ocean, killing all 189 people on board.
But investigators say they are at a loss to explain why the pilots didn’t follow the same procedure performed by another flight crew the previous day when they encountered a similar issue.
A preliminary report into the crash released Wednesday by Indonesia’s National Transportation Safety Committee (NTSC) reveals more details about the final moments of Flight 610, but acknowledges many questions remain.
