During WWII, 6000 young Americans volunteered to fly large unarmed cargo gliders into battle. For these glider pilots every mission was do-or-die. It was their task to repeatedly risk their lives landing the men and tools of war deep within enemy-held territory, often in complete darkness, using only a stopwatch to navigate. Thousands of lives were saved and battles won because of their efforts. In fact, one pilot interviewed said - the 'G' in their emblem didn't stand for glider; it stood for 'guts'.
