I was there too.  Made a REAL BELIEVER out of me.  Small airplanes do have wake turbulence;  Probably off the prop wake IMHO;  others seem to think wing tip vortices.  For those who weren't there:  at Tracy'sin 2002 (I think), Finn started his takeoff run soon after ED had lifted off; as he (Finn) 'rotated' the aircraft rolled left (hard) and the left wingtip lightly brushed the ground.  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. :^)
