your still missing my point, it doesnt matter if he saw it or not, still the pilot of the jets fault
What if the powered aircraft is in distress? Or if you are on base in the glider and he is on short final? This is the usual situation at our field. Who has the right of way then? Consult 91.113 for that. Ahhh...this flying is so confusing. Fault is completely irrelevant when discussing aviation safety; its a word that the lawyers use in the lawsuits that follow.
As far as hijacking the thread, you threw out the gliders. Good luck with it, seriously. I hope you are able to develop your temperament along with your motor skills.
