A fewer days ago, the U.S. NOAA (National Oceanic and Atmospheric Administration) conducted further investigations into the wreck of the USS Yorktown (CV-5) aircraft carrier. This 5th always US Navy aircraft carrier began service in 1937, and sank on June 7, 1942 during the conflict of Midway. The wreckage of the ship was discovered in 1998 at a depth of over 5 kilometres. Turns out he's in perfect shape. Now NOAA conducted the first survey of the USS Yorktown hangar and made a amazing discovery there.
