On March 8, 2014, Malaysia Airlines Flight 370 took off from Kuala Lumpur International Airport. It would be the last flight of the passenger aircraft, though the exact details of what exactly transpired aboard Flight 370 remain a mystery. The plane and its passengers and crew have never been found, and theories about what may have happened to them persist to this day.
Flight 370’s final flight began from Kuala Lumpur International Airport and was scheduled to end at Beijing Capital International Airport. The plane’s captain and co-pilot were each experienced airmen who had no history of showing up to work impaired, and records indicate that no one on the plane was a likely threat to the crew or passengers.
The plane’s last communication with air traffic controllers came around 38 minutes after takeoff, as it was traveling north over the South China Sea. Shortly after this transmission, it fell off of civilian radar and deviated wildly from its original course. Military radar continued to track the plane as it flew out in the wrong direction, flying out toward the Indian Ocean before disappearing from radar completely.
The search for the missing aircraft initially centered on the Andaman Sea, based on the military radar data. However, investigators discovered that the plane’s internal communications device communicated with a satellite for several hours after the plane fell off of radar. This helped narrow the search to a region of the Indian Ocean, though nothing ever actually came of the search.
There are few convincing theories about what happened to the plane. Its disappearance remains baffling because it makes little sense that a skilled pilot would get so lost on a normal course that he would find himself flying in the opposite direction and simply run out of fuel over the Indian Ocean. Some have theorized that the captain and copilot may have lost cabin pressure, leading to hypoxia. They might have turned the plane around when they lost pressure, but lost consciousness shortly after. This doesn’t explain some of the plane’s later hard turns, though.
Others have proposed the possibility that the plane was hijacked by a passenger or crew member. This theory could be possible, but there is no evidence from the plane’s communications arrays that anyone tried to radio for help if such an event did occur.
Some more outlandish theories hold that the flight could have been steered off-course by extraterrestrials, who then guided the plane out of radar detection before abducting the passengers and leaving the aircraft to crash into the ocean. While this theory also has little basis in evidence, it’s a favorite of UFO enthusiasts who point to Malaysia Airlines Flight 370 as evidence of an unexplained phenomenon that could be related to extraterrestrials.
