In 2014, Malaysia Flight 370 vanished during a routine flight to Beijing as air traffic controllers watched the plane deviate from its path then disappear in one of the aviation world’s greatest mysteries.
In the most expensive search-and-rescue in history, teams scoured the seas for any trace of the Boeing 777 that was filled with 227 passengers. Its final radio transmission said “good night” to the controllers, then it was never seen or heard from again in a case that remains unsolved to this day.
