Its not out of gas, the frame rate is just turned way down on the video.  Listen to the sounds, its obvious.

It looks legit to me, compare it to the other videos.

Here we go for the first one. It's an apache going a 'little' faster than yours.




... But wait, here is an apache going tonnes slower:

I don't think it's the optical illusion you are talking about.  Look at the shadow, and the rotors just moves differently than the other videos.  It's fake obviously because if the rotors were moving that slow, the black hawk would be falling not landing.

Look, it's simple physics... first off, if the rotors were really moving at that speed, there would be NO LIFT whatsoever to keep the helicopter afloat. A chunk of metal hovering mid air with no lift?? I don't think so.

Second, a helicopter just falls to the ground if the rotors aren't spinning. It's not like a plane where it can glide since there is still some slight lift created by the wings. It is possible to land a chopper with a dead engine, but the key is that the rotors still have to be spinning when it dies. And more importantly, you have to be a lucky ass mofo.

Last, and this is the most definite reason... the tail rotor gives it away. It keeps the helicopter from spinning around it's axis due to action/reaction laws. You can see the tail rotor spinning pretty fast here, so by default, the main blades have to be spinning at full speed as well. If not, well we would have an interesting crash video in our hands instead.

Anyway, too much effort for a Junk Drawer thread... but what can I say, I like physics.

It is caused by the low framerate of the video camera that recorded it. At the instantaneous point in time when the rotor was captured by the camera, the shadow was too. That makes the shadow arguement void.

In real life, when you see a helicopter fly past where you live, do you see this?


No.

That is what I thought at first, but the rotation should be in the reverse direction if it was falling.  Also, the speed would also be just as fast because of the vortex and the change of pressure.  Instead of counter clockwise as shown in the other videos also, it would be clockwise rotation.  Also, it seems that the pilot has a lot of control over the helo if it was falling.

ok here's an over-simplification, just to illustrate the point.  lets say the chopper has 5 blades, the camera runs at 20 frames per second. if the rotor is spinning at 100 revs per second you would see the same blade in the same place in each frame, since it is making one complete revolution each time the shutter opens and closes, and it looks like the rotor isn't even moving. if the rotor is moving a little faster (105 revs), it appears as if the rotor is moving slowly, as if it were only spinning at 5 revs.  if it moves a littler slower (say 95 revs per second), it appears to be moving backwards.

*Applauds* Thank you for showing up these people that think it's fake for what ever reason. If anyone needs proof of this just look at cars hubcaps when your driving down the road, at some speeds the look like they aren't even moving and sometimes they look like they are moving backwards.

kinda like when you look at a car wheel and when it reaches a certain speed, looks like it starts turning backwards.
Yea, thats what it is.

I got it... it's a video of Battlefield 3 where planes and choppers can fly at ridiculously slow speeds, take out their targets, then be on their way without ever stalling!... it's just like BF2, except with the ultra real graphics you see here.

That was already explained.  I get that.  I know that blades look like they are moving really slow when they are fast.  You can tell the difference between a blade that looks like it is moving slowly, and a blade that IS moving slowly.  The blades look different in that video than in the others that were posted.  Again I know the blades can't REALLY be moving that slow, because it would be crashing, not landing.

Nah, it wouldn't cast a shadow if it was that. Just fat ass rotors that don't need to spin all that fast.
i laughed when i read this, shadows are cast no matter how flast the propeller spins. Light travels at the speed, wait for it, of light. The light cannot pass through the propeller blade no matter how fast the blades are spining, therefore shadows are made.
