I wish as a young, inexperienced commercial pilot I had seen this video. I crashed in a very similar fashion at max weight in very warm conditions when departing from a mountainous airstrip in an ancient, underpowered Cessna I was flying for the first time. The result was a piss poor attempt at a short field takeoff and climb out from rising terrain because I didn't know any better. Luckily we hit the forest canopy, that although ripping the aircraft apart, slowed us down gradually and saved us from serious injury. Unfortunately the occupants of this flight didn’t have the same luxury.
As PompeyPaul says, if a pilot in a similar situation recalls this video and it causes him to think twice and react appropriately, then this video is worth everything.
