In the Wiki article;

one of the names on the chart at the bottom is George Willig. I wonder if this is the “Human Fly” that climbed the WTC?
Yep.
In all, 123 crazies, wastrels, rich men, poor men, beggarmen and thieves got underway in the participating vehicles. Among them were notables like Jacques Villeneuve, Gilles brother (Gilles was an enthusiastic entrant with his old Formula Atlantic car owner, John Lane, until his Long Beach GP schedule interfered), Indy car pilot John Mahler, human fly extraordinaire George Willig, Sports Illustrated writer Sam Moses, Offshore powerboat champions Sandy Satullo and Charlie McCarthy, Karting champ Terry Baker and my partner, Hal Needham, whose plan to run a bogus ambulance was perhaps the best number ever to be tried in the Cannonball.
