"The Whole Nine Yards" (Origins of the saying)

Here is one...

During WWII, american fighter planes were armed with .50 caliber machine guns. The belt used to feed the cartridges measured 27 feet long. Thus if a pilot fired a particularly long burst at an enemy, he was said to have given him "the whole nine yards."      Contributed By"Diddyriddick" of The http://www.historum.com Forum
