In his late teens, Abagnale posed as a PanAm co-pilot, getting lifts on airplanes for free to take him all around the country and the world, allowing him to pass bad checks behind the guise of a respectable airline pilot. By the time he was caught, at age 21, he had managed to bilk his victims, mostly PanAm, of over 2 million dollars - quite a sum in the late 60s, when the story took place.

Posing as Frank Williams, Robert Conrad, Frank Adams, and Robert Monjo, Abagnale also managed to teach sociology at a college in Utah with a fake diploma, pass the bar exam and work in an attorney general's office, pose as a pediatrician and become a temporary resident supervisor at a hospital in Georgia.

Won't ruin it by revealing any more. A fabulous read.
