There was a Korean airline crash which impacted a hillside short of the runway on Guam that had survivors too. According to Korean Air Flight 801 on Wiki and the Korean Air Flight 801 Official Crash site there were 26 survivors. Not a simple off-airport landing, but people did survive.

The point is to take whatever cards you're dealt following a crash and continue playing the game. Your question indicates you are looking at the odds and throwing in the towel before the game starts.

The event my aviation survival kit is designed for is a water ditching. It's based on a Switlik survival vest and has more signalling ability than the vest I wore while on active duty. Following a ditching at sea or jumping out of a plane before a crash, I'll take a PLB, GPS, radio and signal mirror long before I'd even think about an AR. I hope to be found and rescued long before I need to start hunting sustenance.
