CEO Campbell Wilson said in an internal memo that the airline is open to further inquiries and warned against "premature conclusions."

A preliminary assessment in last month’s disaster focusing on fuel being cut to both engines only deepened the mystery for people grieving loved ones.

India’s initial findings into the crash of an Air India aircraft last month raise more questions, according to the airline’s Chief Executive Officer, who defended the fitness of the cockpit crew and the company’s track record of inspecting its fleet.
