The theories have changed dramatically over the disappearance of Malaysian flight 370, which took off on March 8th at 12:41 am from Kuala Lumpur, but lost contact with air traffic control an hour later and disappeared from radar. When it disappeared from radar it was at 35,000 feet about 140 miles off the coast of Vietnam.
It has been six days since the plane and its 239 passengers completely vanished, despite the tremendous search efforts of 57 ships and 48 aircraft from 13 countries, all looking in a search radius that just keeps expanding.
Today, the search radius has widened to 27,000 nautical miles, and the theories of what happened to this plane are changing daily.
The latest theory, which was determined by top aviation experts and being evaluated at this time, is that maybe it landed in a remote Indian Ocean island chain.
However, Denis Giles, editor of the Andaman Chronicle newspaper, says there's just nowhere to land such a big plane in his archipelago without attracting notice, according to CNN.
"There is no chance, no such chance, that any aircraft of this size can come towards Andaman and Nicobar Islands and land," he said.
This supposition of its landing on an island is based on analysis of radar data revealed Friday by Reuters which is suggesting that the plane wasn't just blindly flying northwest from Malaysia.
Although it is just one of many theories being discussed about what might have happened to the aircraft, it seems to be the most reasonable, considering there is not another single clue to guide these searchers, the families or airline officials in a different direction at this time.
Reuters reported that whoever was piloting the plane was following navigational waypoints that would have taken the plane over the Andaman Islands.
The radar data doesn't show the plane over the Andaman Islands but only on a known route that would take it there, Reuters cited its sources as saying.
The theory builds on earlier revelations by U.S. officials that an automated reporting system on the airliner was pinging satellites for hours after its last reported contact with air traffic controllers. U.S. investigators that concluded that the pings didn't come from other planes have led many experts and investigators to believe that the plane flew for hours before completely disappearing.
But this theory begs the question - Who? Why? And what do they want if the plane was indeed hijacked. Experts have pretty much eliminated the idea that the two passengers with stolen passports were terrorists - what else could they have wanted with the plane?
It is a Boeing 777 - one of the most sophisticated and reliable planes in the sky. Could they have wanted just the plane, or are there passengers that might bring a large ransom?
These are questions that have yet to be answered, but not because they have not been evaluated.
At this point, there are no definite answers, and until this plane is located, it is doubtful anyone will know exactly what happened to Malaysia Airlines Flight 370 or its passengers.
