    I assume that they do a really steep take off angle from those bases. Would a steep take off angle, and a wind gust do something about the same? Or would a 747 have enough power/pitch control to get out of a situation line that?

    George, a competent pilot can take off and 'max perform' their aircraft, but it certainly wouldn't result in what we saw in the video. Professional pilots are trained to prevent situations like a stall close to the ground; if a well-trained pilot gets into a stall close to the ground, they will affect a stall recovery quickly to avoid a mishap and hopefully only fly away with a bruised ego. What we saw was well-trained pilots trying to react to something they had no control over and something that was impossible to recover from. The laws of physics just plain don't allow for it.

    That video you posted is probably also the same sort of deal; attempting a take off without the center of gravity in limits. You can tell by that immediate and unnatural pitch up of the nose. If the pilot was able to stop that, they would....I'm sure they were trying. If the CG of the plane is not in a specified range, the control authority may not be available to fly safely. A lot of people have died because they didn't do a proper weight and balance check before flying...it seems to happen a lot in smaller aircraft. Usually some combination of inexperience, laziness, or the ole 'we should be good, I eye-balled it', etc. The difference between this video and the 747 is that these guys probably took off with it wrong from the get go, and the 747 guys experienced a shift in the load after already being airborne.

    Hasn't been declared a load shift yet but sure appears that way.

    tragic, the only accident ive seen thats close to that was a control lock being left in on a q400. the shifting cargo does make sense though.

    My line of business so it's extremely close. I didn't know any of them but two were close friends of one of our Tower Air pilots.

    RIP guys

    Hits close to home; sorry to hear about that dude...I'm sure they were good dudes.

    Hasn't been declared a load shift yet but sure appears that way. We were discussing it at work yesterday. I had beers with these guys in Ramstein last week. Chilling. The company is National Air and they have 2 747-400's that are ex air France jets.

    The cargo was in the proper placement upon take off roll, but most likely shifted aft after takeoff. This large change in weight position changed the center of gravity of the jet, all while the center of lift remains in the same place. This then caused forces to be out of balance and to a degree that the jet's control surfaces couldn't counter-correct. This results in a stall with no recovery as seen in the footage. The only real question to me is how did the cargo shift...will be interesting to see what they determine. I bet a vehicle became unchained and rolled.

    That is nuts. Never seen or even heard of a jumbo jet stalling in air. Looks like his angle of attack was WAY too steep, likely caused by the shifting cargo they were talking about in the article.
    The flight angle didnt look off, rather the cargo probably wasn't strapped down correctly...

    Freak accident for sure....as someone who flies for a living, this would be a nightmare in the cockpit. Literally nothing the flight crew could do to get out of it. Reminds me of an accident from the not too distant past. A Navy C-2 is getting launched off the carrier and during the cat shot, the cargo breaks free and slides aft resulting in an uncontrollable aircraft due to weight distribution. Nothing the crew can do other than try to fly it and basically watch as they plummet to their death. I'm told in this C-2 incident, the cargo broke free on the cat shot killing the aircrew in the back and then subsequently slammed back forward into the cockpit, most likely killing the two pilots before the plane hit the water. I'm heading to fly these planes this summer, and I always have this video playing in the back of my mind.



    RIP to the crew of the 747.

    This is why I drink BEFORE I get on the plane. No point in worrying about it.
    My favorite thing to do at 30,000 feet is to look at my cup of whatever I'm drinking... And think about how gravity still has a hold on it, and us. So if this plane fails, the earth WILL get us back.

    Fuck me I hate flying.
