One hot still day at Watts Bridge, I was in an ASW15 on take-off roll,
and was flung on the ground soon after stabilising in high tow behind a
pawnee. I think I ran into the wing/wake vortiices.

Thanks for linking to the article.
A quick back of the envelope calculation shows that a tens of megawatt
wind farm (like the one in question - 46.5Mw capacity) will possibly
have wake turbulence comparable to a medium sized passenger airliner
like a 737.
The problem with wake turbulence isn't the magnitude but the fact that
the energy is concentrated in small areas. No problem until you run
into them. Under normal circumstances I would expect the wake
turbulence downwind of a wind farm to be dispersed and relatively
harmless but if conditions are just right (wind the right direction
and strength, presence of an inversion, right spacing of the turbines
etc) this may not be so. Might make a nice academic research project
for someone. It would be nice to know. As Mythbusters would say, I'll
call that one plausible for now.
