Hang Son Doong Cave was found by a local man named Hồ-Khanh in 1991. The local jungle men were afraid of the cave for the whistling sound it makes from the underground river. It was not until 2009 that it became public after a group of British scientists from the British Cave Research Association, led by Howard and Deb Limbert, conducted a survey from April 10 through April 14, 2009.
