Dirk Pitt is a fictional character created by American novelist Clive Cussler and featured in a series of novels published from 1976 to 2021. Pitt is a larger-than-life hero reminiscent of pulp magazine icon Doc Savage. Pitt is a citizen of the United States, on loan from the United States Air Force with the rank of Major, after serving in Vietnam as a pilot. He manages to find adventure with his childhood best friend, Al Giordino, despite ending up with an ostensibly desk-bound role as the head of the National Underwater and Marine Agency. Pitt has a commanding presence, a quick wit, and a considerable collection of classic cars. Source: Wikipedia (en)
