It might not take a village to find one’s way along the surface of a complicated airport taxiway/runway/ramp system, but being part of a crew apparently helps. Although crewed airplanes are not immune to committing runway incursions, single-pilots are far more likely to accidentally find their way onto a runway they haven’t been cleared to enter than a professional crew is. At Chicago Midway — an airport with a mind-bendingly complicated layout of runways and taxiways, many of which do not cross each other at right angles — there has been a rash of runway incursions lately. There were a total of three in the past year, more than the previous four years combined, and every one of the latest infractions was committed by a pilot of a transient light GA airplane. If these numbers sound small, think again. All it takes is one moment’s inattention, one bit of wishful thinking, one misunderstanding between you and the controller, to lead to a mistake that could lead to a request for you to call the tower — or, if worse comes to worst, something far more tragic than that.
