Ever since, there have been numerous mysteries about the area regarding what it is used for. Arguably the most well-known rumor surrounding Area 51 is that it is where aliens and crashed spaceships are investigated. Others suggest research on teleportation or time travel is conducted there. Yet still, it remains unknown.

Malaysia Airlines Flight 370

Malaysia Airlines flight 370 disappeared while flying over China on March 8th, 2014. There was no trace left behind of any of the 239 passengers or any of the crew members. Despite international efforts of investigation, only 20 pieces of debris from the plane were ever found.
