Not sure if I've mentioned before, in our area there had been an impressive incident in 1985, when GI Kenneth Thomas Cichowicz based in Germany took a LD hiking, came up to our highest local mountain, crossed an full-face icy glacier, slipped, fell, got heavily injured and survived for 19 days until being rescued.
Due to the 30th annyversary of his rescue, there was a TV Special yesterday http://tv.orf.at/orf3/stories/2876582/ me and my wife were watching. Very touching and impressive, a really strong guy.
Now, a pretty similar thing happened in the same area:
A German guy took a multiday hike over the same mountain, despite of the heavy snow, and happened to posthole down into an extremely narrow and deep vertical hole in the rock named Doline, the kind of that is very typical for Karst.
He got seriousely injured, and survived 4 days being stuck 30 meters inside the hole, until he somehow managed to creep out a few meters and get some weak signal to send an emergency message.

Best thing one can say about the latest incident is, that the phone shortened the guy's stay in the Doline to 4 days.
How he was able to survive this long I have no information so far.
