An interim report related to the probe into the missing Malaysian flight MH370 and the 239 people on board suggests that whoever was at the controls of the ill-fated Boeing 777 when the aircraft disappeared mysteriously was keen to evade detection. According to the report, the guilty was unintentionally helped by mistakes committed at the duty office of the airlines.

The report was released by the Malaysia transport ministry on Sunday, March 8, the first the anniversary of the disappearance of the scheduled flight from Kuala Lumpur to Beijing, reports The Independent.

According to the report, an incriminating record of conversations after the disappearance of the plane shows that even many hours after it lost contact with the aircraft, Malaysia Airlines persisted that the Boeing was flying over Cambodia. However, the airlines authorities changed the story later to imply that the plane was flying over the east of Vietnam's coast.

The transcription with air-traffic controllers in Kuala Lumpur is actually an addendum to the interim report into the loss of Flight MH370 with its 227 passengers and 12-member crew. The transcript discloses the manner in which the events occurred during the early hours of March 8, 2014, subsequent to the captain signing off from Malaysian air-traffic controllers with the words "Goodnight Malaysian Three Seven Zero" at 1:19 a.m. local time.

As per schedule, the aircraft was supposed to continue flying north at 35,000 feet and make contact with controllers at Ho Chi Minh City. However, some unidentified person turned off the transponder on the flight deck, which made the plane imperceptible to civilian radar.

The Independent report quotes a Vietnamese controller saying, "We just see him on the radar screen one time and after a few minutes later disappear."

In fact, Vietnamese controllers are growing increasingly concerned about the flight about 45 minutes following the final contact, but they claimed that their Malaysian counterparts told them, "The aircraft is still flying, is somewhere over Cambodia".

This information came from the Malaysia Airlines operations center.

While a lot of attention was focused on Captain Zaharie Shah, as several theories asserted that he was involved in the aircraft's disappearance. However, the report released by the Malaysian transport ministry has studied CCTV footage of the captain just before the flight, and compared it with matching footage for his three previous departures. "The gait, posture, facial expressions and mannerism were his normal characteristics," the report says, adding, "There were no significant changes in his life style, interpersonal conflict or family stresses."
