You Wouldn't Believe What Scientists Found Frozen in Glaciers and Lakes

 A Long Lost Plane Crash

During WWII, an American Army plane was flying through Alaska when it got caught in a sudden blizzard and went down. The plane got buried underneath 50 feet of snow that eventually turned to ice. All 52 passengers died and were frozen into the plane. This plane was impossible to locate until 50 years later when a hiker accidentally stumbled upon the crash site, as the ice had melted enough to expose the nose of the vessel.
