by Tim O'Neil: The hijacking of American Airlines Flight 119 out of St. Louis on June 23, 1972 was one of many accomplished easily until the nationís airlines and airports clamped down on security. Martin J. McNally, yet another copycat of the mysterious D.B. Cooper, demanded $502,500 and five parachutes, and somewhere over northern Indiana he jumped into the darkness from an altitude of 8,000 feet. Three days later, searchers found a money sack and a gun in fields near Peru, Indiana. A fingerprint led to bruised but alive McNally, who had $13 in his pocket.
