This practice was intense and I am glad I did it. I taught me how difficult it is to do it in real life and that I would not attempt it at 500ft unless at very light weight and favorable wind conditions. First attempt I though I could make it, not even close. I asked my instructor to wait a couple of seconds but he said , do it now all the time. Did 12 attempts in total, 2 of them without warning , first 4 didnt make it, then made the next 8 even the 2 thrown by surprise. It is an extreme training at that low altitude.
