I was involved in an accident in March 2013 (two -seater powered glider). The children of the PIC, who died in the crash, tried to give me a bit of the responsibility, but at the court proceedings they lost as the PIC is the person in the left hand seat. There was no argument about that!! I'm still suffering from that accident (I can't walk)
Just how many people were on board this two seater? Seems PIC, you, children (plural), making at least four. Been there, as a young teenager a local instructor took me for a night flight in a two seater with his daughter sitting on my lap, included a few loops over a well lit city.
