I love this video of 2 helicopter pilots on a regular Robinson R-22 training flight, turning it into a rescue mission to retrieve a P-51 Mustang RC Airplane from the top of the trees. What a coincidence that they were just flying by, watching it happen, and the instructor pilot was so nice to get it out of the tree and give the rc airplane back to the owner who would probably never got it out of tree. They will all tell this story for the rest of their lives. This only happens once in your lifetime. Kudos to the helicopter pilots!
