I do not have anything more than a rumor that "someone" apparently lost a UAV in the same area at the same time, but nothing confirmed , therefore I was fishing here.
Maybe I should have posted this on the military forum
But seen the impact crater , it is doubtful physical evidence will be easily found before the snow melts or if at all, and unless spotted visually before by the crew,I do not think the CVR/FDR are going to help much to validate or invalidate that possibility..
