Many mysterious things have happened to flights since commercial air travel became available to the general public in 1914. To this day, people still wonder what happened inside the planes of flights 93, 11, and 175 on September 11th of 2001. However, out of all strange things that have occurred on flights over the years, never has a flight simply vanished, never to be found.

On March 8th of this year, Malaysian Airlines Flight 370 took off from Malaysia and was scheduled to land in Beijing just several hours later. However, just a few hours after taking off, it completely went off the radar. Military radar shows that over the South China Sea, flight 370 took an extremely sharp turn, and immediately changed altitude, flying either above or below radar detection. Expert analysis have said that this maneuver was likely to be intentional.

Also, at some point during the flight, the backup radar detection device was turned off from the cockpit. Experts have yet to figure out whether the pilots turned the radar signal off themselves, or if hijackers invaded the cockpit and forced the pilots to turn off the signals. Either way, with absolutely no way of detecting the plane, flight control has no clue where the plane landed, and has yet to see any trace of the plane to this date.

Within 24 hours of Malaysian Airlines Flight 370 going off the grid, both the pilot and the co-pilot’s houses were searched. FBI Investigators have not found any information that seems overly suspicious. In fact, a call made from the co-pilot’s cell phone halfway through the flight has led detectives to believe that the pilots were most likely attempting to inform someone of a hijacking.

Of the flights 227 passengers aboard, four were found to have either stolen or fake passports. Out of 20 Plant High students that took a survey on the topic, 70% believe that these four suspicious passenger were the reason for the flights disappearance. Other student theories included that the plane simply had an engine failure and plummeted into the ocean, and the pilots were behind the whole thing.

Though the search continues, over eight million sq km has already been covered in hopes to find the missing plane, covering a good portion of the Indian Ocean, and parts of Australia and Asia. It has now been over two months since the plane went missing and search crews have yet to spot Malaysian Airlines Flight 370.
