In my granddad’s day, an airport hot spot was a bar or a diner close to the field where pilots, mechanics, line service personnel, and aviation enthusiasts could gather for a cold one at the end of the day. Today, that designation refers to a point on the airport grounds where it is possible, if not likely, that confusion may result in an airplane, truck, car, or other motorized vehicle straying onto a chunk of pavement other than the one the pilot or driver intended — potentially with tragic results.
