Tough video to watch. It bounces incredibly hard the. Pitched down violently. Not sure if it was pilot induced or what

RIP and condolences to those who know the flight crew.
Im no expert, but it looks (Cam 1 and 5) as if they might have been trying hard to get it on the ground which started the initial bounce and porpoise. Which I guess when landing with a significant tailwind it would make sense to "get it on the ground". You can see how much of a tailwind there is by the snow drifting across the ramp. Which usually takes about 10-15 knots of wind to make snow drift like that. Again, Not trying to be an expert or start an argument just stating my observation.

That violent pitch over reminds me of the FedEx MD-11 that bounced and spoilers failed to retract and caused the same pitch down motion.
I believe one of the surviving pilots has left the hospital.

A link to an article to go along with the previously link videos of the mishap.
http://www.channel4000.com/news/Vide...Aspen/24047544
From the article:
"The deceased co-pilot was identified as 54-year-old Sergio Carranza Brabata of Mexico. The Pitkin County coroner listed the preliminary cause of death as blunt force trauma."
An inaccuracy from the reporting:
The black-and-white video shows the plane exploding in flames the instant it touches the ground. As the scorched aircraft continues down the runway, it leaves a long trail of fire shooting into the sky
- - - Misleading in that it bounced at least once, possibly twice according to JNB, before "exploding in flames".

I see two bounces. This is "classic" porpoise.
First bounce is caused by landing on the nosewheel, trying to force it on. As the mains come down, the AOA increases and you're flying again. At this point, you MUST hold the nose up and go around. This is your one and only chance to save it. You may hit again, but if you hit on the mains you should be able to recover.
Otherwise, the momentum of the first bounce off the mains forces the nose down again, hard, and you're once again aimed at the pavement. In the IR video you can see brief "flash". This could easily be sparks from the nosewheel collapsing.
After this second hit, they are pretty much along for the ride, high bounce and crash with not enough airspeed to affect the outcome.
I don't mean to sound like a flight instructor, this is flying 101 for most of us. But it bears repeating. This is preventable.

It does look very severe. Could it have been a tail stall? I don't know the airplane. I don't even know if the tail has de-icing equipment installed. It's always bothered me that the 737 doesn't have any tail de-icing. (Add 10kts)
