So you're on vacation and you just need a short commuter flight from one town to the next and then the pilot says "Hey we have to crash land ok?"  This brave kid just keeps telling himself it's all gonna be ok, yet say's he's leaving the video for his family. What I think happened was a failure to pull the Carb Heat knob. With passengers flying at altitude over snow, the pilot had to have had carb heat. A common mistake is to turn on the cabin heat, taking away from carb heat, then running a little rich, which cools the carbs instead of running lean for altitude and letting the engine run hot. The plane looked a little overweight... ah well. You get the point. Watch the video before I ruin it with jargon and what not ok? GO BACK UP, CLICK PLAY!  :-)
