Stop spreading rumours that the plane has been found or whatsoever, unless @MAS have given out a statement, non of that is believable.

The mystery of the plane's disappearance heightened as the pilots of the flight had not reported any problems with the aircraft.

"The aircraft had not been at altitude long and that strikes me as very, very odd," aviation expert Captain JF Joseph, who has 44 years flying of experience, told TIME.

"It's too early to say if there was a bomb or terrorist activity, but it lost contact just as it began to level off at 35,000 ft. It would give some indication that what occurred was catastrophic or somewhat instantaneous."
