I was going to suggest that you get one of those R/C helicopters but, I
think you would just be putting so much hardware into the trees while
trying to retrieve the last thing you used to try and get the previous
thing out of the tree.
"I know an old lady who swallowed a fly" ?
Maybe I should put Henc on this. Design a drone that can rescue a
plane from a tree and not get stuck.
In my youth, when I flew U controls, I worked in a hobby shop part time.
One guy who flew RC told of having to climb a tall eucalyptus to retrieve
his plane. Was a telephone lineman, and had his climbing gear in the car.
