A preliminary assessment in last month’s disaster pointing to pilot action only deepened the mystery for people grieving loved ones.

An official report on the world’s deadliest aviation accident in a decade, seen by CNN, has answered one key question – but raised others.

The Indian Commercial Pilots’ Association (ICPA) on Sunday condemned insinuations of pilot suicide as baseless and insensitive, saying the crew acted in line with their training for an emergency. The pilots associations have also questioned the selective media leaks hinting at pilot error ahead of the publication of the preliminary report.
