As unbelievable as it sounds, my phone had fallen 13,500 ft, and was still sending out a signal.
According to my iPad, it was less than 1/4 mile away, and laying on top of a factory roof. We loaded up and drove down, only to interrupt a post 4th of July company picnic.
After telling them why I was there, they offered to lift me to the roof to look for it. I didn’t think there was anyway that the app could be that accurate, but low and behold, it was right where my iPad said it was, and it was still working!!! 13,500ft, 120mhp, to a steel roof, and still alive!!
