The search is still on for the Malaysia Airlines flight 370, which mysteriously vanished somewhere en route from Kuala Lumpur to Beijing on March 7. There were 239 people on board, and so far, all clues have led nowhere.
Flight 370 was cruising around 35,000 feet when it dropped from radar with no signal from pilots, which is almost unheard of in the aviation world. Authorities believe it may have disintegrated in mid-flight, but no wreckage has been recovered after a weekend search with 34 aircrafts and 40 ships. It's extremely rare for an aircraft to suddenly vanish, without warning, during cruising altitude, as most airplane accidents occur during takeoff or landing. Since 2003, only seven fatal commercial jet accidents have occurred during cruising altitude.
While the cause of the Malaysia Airlines flight 370 incident is still unknown, the map below plots a few other crashes that occurred during cruising altitude, or problems that began during cruise, as the result of mechanical failures or technical errors.
