Stranded motorist effects own rescue by attaching his phone to a drone and sending it up to higher altitude
Rather than wandering off on foot in search of help, he stayed with his vehicle, which provided shelter from the elements. Conveniently, he also happened to have a drone along with him, which provided him with an opportunity to get some help. After typing a detailed text message to a friend describing his situation and exact location, he attached the phone to his drone and sent it straight up a couple of hundred feet — enough to get a line-of-sight connection to a cell tower.
When he brought the drone back down a few minutes later, he found that the queued text had been sent, and the cavalry was on the way. The Search and Rescue unit was able to locate him, and as a bonus, also found someone else nearby who had been stranded for days.
