Real or fake ??

Can you post a link?

[Less Hair]

The guillotine maneuver. Can this be real with all the boxes?

[typerated]

First a stealthy Blackhawk.

Now a Chinook without rotorwash ?

Simon,
Like you, I don't see Wastebook/Twatter links owing to my security settings - if you want to see what's being written about, you have to press the "quote" button in the post. When the next page opens, right-click on the URL and open it in another tab.

typerated,
I can definitely see downwash in the video - pale demarcation line along the ground between the ISOs that follows the aircraft.

What a stupid, stupid thing to do - let alone be filmed whilst doing it. Echoes of South Cerney and other tragedies.

All fun and games until someone loses an eye

[albatross]

I find it very interesting that the helicopter is in a right bank yet not turning.

[Old and Horrified]

Is it my elderly eyes, or is the front rotor spinning the wrong way?

[SASless]

Old....my old eyes saw the same thing but at the very end the Forward Head Blades are in correct sense and in the very final frames seem to be turning in correct sense that agrees with the blade leading edge appearance.

The video shows a not so bright bit of judgement and commonsense......there is a time and place for such a kind of flying but not as seen in the video.....In my most humble opinion.

Yes, the South Cerney wazz was a hoot.

Fake. the rotor blades on the front rotor are on backward. The front rotor advances on the right side, USA style, the rear rotor advances on the left side, EURO style.... The movie has the front rotor advancing on the wrong side, and that isn't looking at the blade rotation, it's looking at the blade root fitting to the blade inner chord.

The rear rotor in the video is advancing on the left side too.. looking at the root fittings, so, yeah, is fake, da. Would be entertaining to fly a tandem rotor with both rotors advancing on the same side, that is they are clashing in the mesh... opposite direction of the blades over the transmission drive tunnel. Would be fun as far as torque offset goes or yaw pedal, good for the first 0.1 of a second,

Forget about the flight dynamics that are wrong too or the mother of all dynamic rollovers. Forget about the lack of coning...

[lelebebbel]

Yep rotors look identical, and even if you slow it down to 0.25 speed, clearly both spin clockwise. Can't put this down to camera frame rate issues either.

Funny that someone would go though the effort of creating this, which likely took a bit of time, without bothering to find out how a Chinook actually flies

[SASless]

Two Chinooks left over from the VNAF, both A Models, on display by the current owners in a Museum in Saigon and one at the The Shanh combat base both have the Rotors attached wrong way around on the forward head.....but obviously are not flyable.

I'm not going to definitely say fake or real, and I'm not going to get involved in rotor speed Vs shutter speed discussions, but on the downwash front I'd say it's highly unlikely to be real - a Chinook leaves a visible wake on a sea's surface at anything below about 100' ASL, to give some context as to how much downwash you can expect. At the heights in that video (10-15' AGL, a standard shipping container is 8ft6) then I'd expect nothing less than chaos, destruction and mayhem immediately behind that cab. There's open container doors and fod everywhere, and nothing moves. The only thing visible under the cab is some shadow, and that could have easily been edited in.

That said, to my eye, a Dutch config CH-47 and a fairly convincing model of one if it is, good eye for detail, though admittedly hard to make out with poor contrast etc.

[WB627]

I'm not an expert on Chinooks, but I am a bit of an expert on containers and IMHO, they look rather large in comparison to the Chinook.

Caveat, I could be wrong

I think the rear rotor is also the wrong way round on this one.

[DuncanDoenitz]

Both rotors have incorrect rotation.

(Or they've installed the cockpit at the wrong end. Easily done; this is why we have duplicate/independent inspections).

[Vessbot]

My vote is "real." A few of the comments (why isn't it turning with the bank, where is the wake) seem to be based on the video speed being real time. It's actually slowed down quite a lot.

As for the blades, we're seeing correct rotation of CCW of the front and CW of the rear when seen from above, but the camera is in that very narrow space, where we're seeing the front rotor from above, and the rear rotor from below. That aside, when looking at a poorly lit silhouette, it's easy to fall into a wrong-way spinning illusion like the spinning dancer:

Also if it was fake, it would have taken a hell of a lot of coordination for all the people to be looking/dodging at the righ time.

I agree with Vessbot. I’ve got plenty of hours on chinook and there’s absolutely nothing on that video to suggest it’s a fake. The rotors are definitely turning correctly and the camera pans too fast to allow you to view the areas that would have been affected by downwash. So I’d say that was real.
