Colonel Paul Irvin "Pappy" Gunn (October 18, 1899 - October 11, 1957) was a former U.S. naval aviator known mainly for his actions in the Second World War as an officer in the United States Army Air Forces. He was known as "an expert in dare-devil low-level flying," and recognized for numerous feats of heroism and mechanical ingenuity, especially modifications to the Douglas A-20 Havoc light bomber and B-25 Mitchell medium bomber that turned them into attack aircraft. Gunn died when his plane crashed in a storm over the Philippines on October 11, 1957 killing all aboard.
