Data logs in the final report -- released late July -- into the disappearance of Malaysia Airlines Flight MH370 are incomplete and believed to be modified, experts claimed to hint at a cover-up. The allegations were made by experts independently investigating what happened to Flight MH370, which went missing on March 8, 2014, with 239 people on board while on its way from Kuala Lumpur to Beijing.

According to Victor Iannello, who leads the Independent Group investigating the plane's disappearance, some anomalies were found "in the message logs that were included in factual information released by Malaysia," as well as the safety report. The Independent Group had previously worked extensively with the Australian Transport Safety Bureau, which was leading the MH370 search.

"It is disappointing that more than four years after MH370's disappearance, we are still asking Malaysia to release withheld data," he posted to his blog Friday. "The anomalies suggest the traffic logs appearing in the reports are not complete, and what appears in the reports has been modified."

Iannello wrote in his blog that the facts surrounding the Aircraft Communications Addressing and Reporting System traffic log “are more suspicious, with the filter parameters used to generate the remaining pages (after page one) of the report changed so that VHF (very high frequency) messages, if any occurred, were excluded.”

"The military radar data is another example of a data set that has never been released in full despite its significance in providing information about how the aircraft was flown after the diversion from the flight plan," Iannello added. “It is important that Malaysia provide a complete, unmodified log of all ACARS communications on Satcom, VHF and HF (high frequency) paths. This is significant in light of questions surrounding the delayed response of Malaysian authorities after MH370 went missing.”

On July 30, Malaysia released a "final" report stating that investigators were unable to determine the cause of the plane's disappearance. The report said Flight MH370 deviated from its path not because of anomalies in the mechanical system or under autopilot but under manual control. However, investigators said they have not ruled out the hijacking theory. The report had also sparked condemnation from the families of those on board the jet as they accused the Malaysian government of a massive cover-up.

A multimillion-dollar search carried out by Australia, Malaysia and China, for over three years yielded no concrete clues as to the plane's whereabouts. Earlier this year, Malaysia signed a "no cure, no fee" deal with U.S.-based company Ocean Infinity. However, this search also turned fruitless as the plane was not found.

Since the plane's disappearance, several conspiracy theories made the rounds. Last month, a theory suggested Flight MH370 was most likely brought down by a stowaway on board the jet.

A more recent theory claimed that the missing jet was in the jungles of Cambodia. The claim was made by tech expert Ian Wilson who searched for the plane on Google Earth, according to the Daily Star. Another similar claim was debunked last month when the plane was said to have been spotted on Google Maps off the coast of Padang, Indonesia.

Earlier, some theorists claimed MH370 was shot down by military forces. While some said the plane was accidentally shot down during a joint U.S.-Thai military exercise, others blamed North Korea of doing so.

There were also theories of a possible electrical issue resulting in a fire on board the plane, which probably caused the crew to pass out from smoke inhalation, and the plane continued on autopilot until it ran out of fuel, eventually crashing into a remote part of the southern Indian Ocean.

Some theorists allege the jet entered another Bermuda Triangle, also known as the Devil’s Triangle, located in Asia in the Indian Ocean.
