March 18, 1982 - Jennifer Mack’s Bogus Plane Ticket is Issued In an effort to impress Jennifer Mack with his elite hacking skills, David Lightman broke into an airline mainframe and procured her a free ticket to Paris on March 18, 1982, scheduling her to depart from Chicago O’Hare International Airport in August of the following year. He also entered their school’s computer system to change their grades and attendance records.
