RE: Stuck high in a tree now what?
You need the following
Crossbow OR conventional bow and arrow.
Fixed spool fishing reel with some 30lb nylon [approx]
You are likely to need some stronger line.
Tie 30 lb nylon to quarrel/arrow. Shoot over branch. Try to dislodge plane. If required pull heavier line through and use that.
Worked for me and many others.
