that is one of the crazyiest videos ive ever seen 8 people killed they are saying it was due to load shift

[muddywings]

I'm not in the game any more but that is just haunting!
God Speed and Here's a Toast....

[Sparky]

That is scary. It just fell out of the sky.

[patrick0685]

that scary...RIP

[Bailey Guns]

I've never seen anything like that. Unreal watching a 747 just fall out of the sky. Pretty tragic.

[n8tive97]

Wow, that sucks.... RIP

[ChunkyMonkey]

RIP... For few sec, it just hovered til gravity > thrust.

Embedding it here..

If it happened yesterday, why does the dash cam say 2013/02/01? Did someone forget to set the clock on it?

That is truly scary, I'm surprised the cop backed up as slowly as he did, I would have floored it in reverse...

[hatidua]

The last 10 seconds had to have been pretty awful for those onboard...

[griebel303]

That is eerie to watch it stall and just hover there for a second. RIP to those onboard

[baglock1]

Unreal. For the 7 souls on board, RIP


RIP... For few sec, it just hovered til gravity > thrust.

Actually until gravity > lift. Thrust is the opposing force of drag.

Probably not the time to nitpick, but I'm an engineer. Nitpicking is what we do.

[HoneyBadger]

Those damn physicks are out to get us! RIP...

[Tinelement]

I hate flying.

That gave me the heebie geebbies.

[BigBear]

incredible... It really looked like that pilot was trying his hardest to get those wings level until he ran out of altitude... poor guys.... RIP

[Shootersfab]

Dam thats crazy! Thats not a good day

It happened yesterday...friend of mine at Bagram told me about it while we chatting for work.

Looks like a classic stall,too much angle of attack with insufficient airspeed.

[Chad4000]

holy wow....

[Gman]

I could see if the load broke loose on take off and slid to the rear, it was all over. Pilot probably had the yoke pushed forward with no effect. Seeing that it was on take off, plenty of fuel to feed the flames as well. Fortunately for them, they didn't feel the burn.

[Cylinder Head]

Wow just unreal. That is a completely crazy video.

[USAFGopherMike]

Could be a pilot induced stall or a weight/balance issue or load shift. Pilot recognized the stall too late it looks like. A shame for the 7-8 on board. RIP.

Edit - confirmed: load shift on take off. Nothing the pilots could have done. Doomed from rotation.

Given the angle of attack on that thing, it was probably thrust more than lift keeping it in the air as long as it did.

Given the angle of attack on that thing, it was probably thrust more than lift keeping it in the air as long as it did.

If that was what the OP meant, it's possible there was a significant portion of thrust contributing to the vertical vector.

[T-Jet]

Who's aircraft was it ?

[clublights]

Depending on which model of 747 and which engines it has .....

it could be pushing 280,000lbs of thrust.

Of course max takeoff is 987,000lbs

Somebody is going to lose their job over that one...
How could the officer not say anything but for his dog to be quite? I would have said a few choice words.

[rondog]

Daaaaamn......

[sniper7]

Ouch, not good. Rip

[RMAC757]

I hate to speculate and am hesitant in doing so but it looks a lot like an uncontrolled weight shift causing an extreme aft CG. It's happen more than once before with this type of operation and the previous ones were fatal as well. If that was the case, there's nothing they could've done once they were airborne.

"To fly west my friends......"

Oh, I have slipped the surly bonds of Earth
And danced the skies on laughter-silvered wings;
Sunward I've climbed, and joined the tumbling mirth
Of sun-split clouds--and done a hundred things
You have not dreamed of--wheeled and soared and swung
High in the sunlit silence, Hov'ring there,
I've chased the shouting wind along, and flung
My eager craft through footless halls of air.
Up, up the long, delirious burning blue
I've topped the windswept heights with easy grace
Where never lark, or even eagle flew.
And while with silent, lifting mind I've trod
The high untrespassed sanctity of space,
Put out my hand, and touched the face of God.

Another thing that probably led to the load shifting was they do some pretty steep departures out of there to avoid RPGs and whatever else bad guys may want to shoot at planes taking off there. Once you get a heavy load moving/falling back you have no hope. Also if that load was farther forward and then went aft it could have pushed up against other items and had a snowball affect taking everything to the aft.

I actually had a similar experience one time in a light twin. Didn't realize there was a case of oil all the way aft as the guy i was flying with threw his jacket over it and pushed it back. We took off and got a bit of a surprise. Had to fly with the thing trimmed nose down for just about the whole flight. Didn't realize what the actual problem was until we landed. Someone in Atlanta ended up a with a free case of premium aviation oil that day.
