Master Sgt. William Carson, 8th Fighter Wing flight safety non-commissioned officer tested goggles that simulate varying percentages of blood alcohol content levels, at Kunsan Air Base, Republic of Korea, May 26, 2010. People will be asked to drive a golf cart in a restricted area while wearing these goggles. The purpose of this is to simulate the impairment caused by alcohol and its effects while driving.
