The investigation for the decade's biggest aviation mystery, the Malaysia Airlines Flight MH 370, continues. Recently, Australian investigators reported that the Boeing 777 suffered a power outage just 90 minutes after taking off.

It is possible that the plane's vital equipment was tampered with during its flight. According to Australian Transport Safety Bureau, "A log-on request in the middle of a flight is not common and can occur for only a few reasons. These include a power interruption to the aircraft satellite data unit (SDU), a software failure, loss of critical systems providing input to the SDU or a loss of the link due to aircraft attitude. An analysis was performed which determined that the characteristics and timing of the log-on requests were best matched as resulting from power interruption to the SDU."

According to some reports, if Malaysia Airlines tried to contact the plane, the satellite would have logged on to override the system. It has been confirmed that Malaysia Airlines contacted the plane twice over six hours, following its disappearance from the radar. Indication of inconsistencies on the data log conclude that malicious tampering may have been involved.

However, some experts say that the system would have had a back-up, "The aircraft has so many backup systems. Any form of power interruption is always backed up by another system. The person doing it would have to know what they are doing. It would have to be a deliberate act to hijack or sabotage the aircraft." Aviation expert Peter Marosszeky, from the University of New South Wales, told the Daily Telegraph.

Once again the recent investigation results gave more legitimate and possible evidence that could finally resolve one of the greatest unanswered aviation mysteries in the history. Until now not a single piece of the Boeing 777 has been found, nor any sign of the 239 people that were on board.
