My take after reading the NTSB report is the glider pilot looked away to adjust a GoPro, Got High on the tow early and drove the tug into the ground.
Does this sound correct?
God Damn it. These are easily preventable accidents.
Killing Tow Pilots like this is very bad form.
When I was towing I'd look pilots in the eye that I didn't know and say " If you get high on me your getting rope, immediately." Got it?
