He was on base, made several circles and climbed a little, and then broke into a spin. The standard cirus did about 2 revolutions before it hit the ground. This was no freak atmospheric event, except that the air is more turbulent near the ground. Don’t f*#~k around down low...

A few years ago a friend of mine, flying at a contest, spun at low altitude and died as a result of the crash. I wasn't there.
I resolved that, If I saw such low thermaling I would call the pilot and say "you are scaring me, please land and I'll buy you another tow". To date , I've bought 2 tows. Money well spent.
Maybe someone else could save a friend if they have the chance and make that call.
