9M-MRO did not use oxygen generators for the passengers. It had the optional bottled system for the passengers.
The turn that diverted the missing Malaysian Airlines plane off its flight path was programmed into the aircraft’s computer navigation system, probably by someone in the cockpit, the New York Times reported.
That reinforces the increasing belief among investigators that the aircraft was deliberately diverted, the newspaper said in a report late Monday, quoting US officials.
Rather than manually operating the plane’s controls, whoever altered Flight 370’s path typed seven or eight keystrokes into a computer situated between the captain and the co-pilot, according to officials.

The Times said the changes made to the plane’s direction through the Flight Management System were reported back to a maintenance base by ACARS, according to an American official.
This showed the reprogramming happened before the ACARS stopped working, at about the same time that oral radio contact was lost and the airplane’s transponder also stopped. This fuels suspicions that foul play was involved in the plane’s disappearance.
