New doubt cast over jet timeline

New doubt cast over jet timeline

Officials have released a new timeline suggesting the final voice transmission from the cockpit of the missing Malaysian plane may have occurred before any of its communications systems were disabled.

The latest development adds more uncertainty about who aboard might have been to blame.

The search for Malaysia Airlines flight 370, which vanished early on March 8 while flying from Kuala Lumpur to Beijing with 239 people on board, has now been expanded deep into the northern and southern hemispheres. Australian vessels scoured the southern Indian Ocean and China offered 21 of its satellites to help Malaysia in the unprecedented hunt.

Investigators say the plane was deliberately diverted during its overnight flight and flew off-course for hours. They haven’t ruled out hijacking, sabotage, or pilot suicide, and they are checking the backgrounds of the 227 passengers and 12 crew members, as well as the ground crew, to see if links to terrorists, personal problems or psychological issues could be factors.

Malaysian Defence Minister Hishammuddin Hussein said finding the plane was still the main focus, and he did not rule out that it might be discovered intact.

“The fact that there was no distress signal, no ransom notes, no parties claiming responsibility, there is always hope,” he said at a news conference.

Malaysian Airlines CEO Ahmad Jauhari Yahya said an initial investigation indicated that the last words heard from the plane by ground controllers – “All right, good night” – were spoken by the co-pilot, Fariq Abdul Hamid. Malaysian officials said earlier that those words came after one of the jetliner’s data communications systems – the Aircraft Communications Addressing and Reporting System – had been switched off, suggesting the voice from the cockpit may have been trying to deceive ground controllers.

However, Mr Amhad said that while the last data transmission from ACARS came before that, it was still unclear at what point the system was switched off, making any implications of the timing murkier.

The new information opened the possibility that both ACARS and the plane’s transponders, which make the plane visible to civilian air traffic controllers, were turned off at about the same time. It also suggests that the message delivered from the cockpit could have preceded any of the severed communications.

The search now involves 26 countries.
