The problem is generally the limited capability of a remote pilot who has vision limited to only one or two cameras. They haven't matched the human brain just yet, and they haven't come close to the periphial vision and the ability to hear and feel at the same time. Getting a load into a spot if dropped can be done by a drone, but getting down into the trees is another matter. But then again, our pilots today don't do anything but approved LZ's that have security. Times just ain't like they were when we were young and stupid. Along with being ten feet tall and bulletproof till the stuff hit the fan.
