Could someone explain what they mean by a stall? Curious what happened but I dont really understand.
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
My AFC gave me an ABS CEL code of LOL while at WOT!

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??

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

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

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.
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
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.

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.
