allah akbar!

in all seriousness though, I can relate, i've done that many times in every flight simulator. lol!!!!

i wonder what happened, unbalanced aircraft?

Bagram airfield crash 29 apr 2013 - YouTube



Probably load shift to the rear of the plane, or improper loading of heavier goods in the tail section.

[Gumby]

Holy crap, it was so eerie to see such a massive plane hang in the air momentarily before coming down. :eek:

[Ulic Qel-Droma]

OR maybe the pilot was like:

"CHECK THIS OUT GUYS!!!"

then moments later, "fuck."


yeah the load probably was not balanced... or not strapped down properly. maybe it slid to the back and... totally fucked the weight up.

[westopher]

I'm no pilot, but its takeoff angle seemed INCREDIBLY steep. Could a stall under such heavy load be the simple culprit?

This. An airliner does not have the thrust to sustain such a high Angle of Attack... I wonder how the hell that nose-up attitude happened?

[tool001]

^ steep due to obvious reason (Afghanistan) security,, seems like engine just stalled.. alot of airports need planes to make steep approach and take off, but in this case...looks steep...could be just the angle of recording..

[Harvey Specter]

Wow, looks like the plane had too much much weight, stalled and than crashed.

[AWDTurboLuvr]

Cargo must've become loose and shifted all the weight to the back suddenly. Take-offs are the most stressful on the plane.

[sonick]

That video, holy fuck :fulloffuck:

Yes, because date stamps on cheap dashcams are always the most accurate.

It was a National Air Cargo plane heading from Afghanistan to Dubai...

Definitely seems like a cargo shift, its happened before.
Apparently the pilot reported a stall and as you can see tried compensating for the yaw and looks like he did a decent job of getting the wings level and nose down but they were way too low to ever make a recovery.
Thats a very haunting video to watch.

Lol no. Most stressful on the engine, sorta.

Are you kidding me? He held the stall until he got a wing drop, that's pretty impressive considering the stick shaker comes on so early in that plane.

As for the steep take off angle, ya it's stupid steep. The only time that a 747 can "do" that is if it's empty. Talking to my sim instructor this semester and Cathay Pacific would sometimes be doing like 500fpm climbs out of Vancouver on a hot day with a full load of passengers.

What i'm thinking is that the cargo shifted so bad that no amount of elevator down could overcome the rearward cog

[twitchyzero]

damn that was scary to watch

[Hondaracer]

thought explosion would be bigger for such a large plane

[El Bastardo]

Holy shit. National is one of our clients and one of our sales guys told me about this today. I had no idea there was a video

[yray]

Push down, trim down, pull up trim up

If I was flying the plane. I would've broken the trim switch.

Rip

[LiquidTurbo]

Wowwowowow.

Sad to just see 7 lives vaporize like that.

[2 n r]

HOLYFUCK


rip..

[daytona675]

at least they died instantly. RIP.

In this case, I could imagine the pilots yell, ENGINEER MORE POWER! BUT NO RESERVE POWER available :(

[TheKingdom2000]

That was crazy.

RIP

[Yodamaster]

Too low terrain, bwoop bwoop

Not enough airflow over the wing, center of pressure moves forward, once critical angle is attained, center of pressure moves rapidly back, plane falls on its face

[SpartanAir]

I'm also shocked that the guy recording the video had no reaction whatsoever to a plane falling out of the sky and exploding in front of him at 0:23, until 1:15 when he says "oh, fuck".

How does one stay totally silent when you see that??

Ever heard of shock?

[LiquidTurbo]

Saw this posted on FB about it.. very relevant..

"Whatever industry you are in, please take your job seriously and take responsibility because it costs people's lives and there's nothing you can do to bring them back..."

[Infiniti]

little to no chance of recovery from that stall

god bless Afghanistan

everyone is different. They react different in situations.... for ex. (girls scream and shit :rukidding: )

That's one nasty ass stall...
but how the hell do you bleed off your airspeed like that?
Bad CofG, shifting cargo?

Nasty stall near the ground, turns into a wing drop. and boom goes the dynamite

[nekthx]

maybe a Vx climb? in hot and humid loaded heavy?
poorly loaded with aft CofG? then a cargo shift.

[Kidnapman]

Shit, I haven't seen a stall that bad since I last played Flight Sim flying over South America.

[godwin]

They were carrying MRAPs apparently one of the tie downs failed.

Tell us more about how you would have handled it right after rotation mr. expert pilot?

Could someone explain what they mean by a stall? Curious what happened but I dont really understand.

take your index finger and point it straight up, balance a ruler on it and pretend theyre wings... imagen the airflow with forward moment is providing lift to your wings ... hypothetically everthing is in balance... now your finger and your wings are in equilibrium... move your finger backwards on the axis of what would be the planes fuselage and your gonna need more weight toward teh front to keep it balanced...
move it backwards and vice versa......
put all the weight to the back without being able to thrust forward enough for your wings to continue providing lift = stall.

i hope that makes sense.
thats really the simplest way i can explain c of g... maybe the expert pilot guy can explain it better than me.

[Ulic Qel-Droma]

lol the easiest way to explain a stall without getting all scientific is this:

when you make a crappy paper airplane, the kind where when you throw it, it automatically flies upward.

it flies upward and "loses power", and then it just kinda nose dives and crashes.

that's a stall.


so my question is... if you have thrust vectoring, isn't it a lot harder to "stall"? since you can just go full power and the computer can auto adjust it and just "balance" as you slowly descend facing upward lol.

A stalled condition is a reference to the airfoil and the relative airflow.
If you have thrust vectoring and you are dependent on the thrust to keep you afloat (like a hovering Harrier), the wings are technically stalled beyond anything since the angle of attack to the relative airflow is greater than 15 degrees (15 degrees is generally accepted as the critical angle of attack)

If the wing isn't creating any lift, and if the angle of attack is greater than 15 then the airfoil is said to be in a stalled condition
:accepted:

Once you stall a swept wing aircraft your chances of recovery are pretty much close to zero unless you have heaps of power. They simply aren't designed to fly at low speed.

[GabAlmighty]

Well when you rotate in that plane you go to about 18* nose up a rate of about 3*/sec. Once it started going past that you start pushing the nose over, you know that thing you do to break a stall? That being said, if the cargo shifted so bad that no amount of forward pressure could break the stall then he was simply sol from the begginning.
