Scared me silly; Finn had no idea how close >he came to ???????. Glider pilots know all about wake turbulence from small airplanes. To get your glider ticket, you must be able to "box the wake" of the tow plane. You descend through the wake, then you fly a "box" all around it. . If you get too close when you are on one side or the other, you catch a wingtip in the wake. Generally, most folks only make this mistake once. :^)
