Worth looking at the longer version as was posted previously by Nutloose.

Includes the camera shake/sound as the wake/ wash or rotor tip vortice hits the camera.

If I was guessing, as suggested earlier, whilst it’s not completely conclusive from the video, my guess would be that’s a Dutch D model. All of which retired at the end of last year in favour of F models.

I'd say that was fake - given that ballerinas generally don't have such quite spectacular breasts!

When watching that clip, select 2x speed via the three dots on the bottom right. Double again may be almost true speed, but it all makes more sense when sped up 👍

If it was Dutch, I’d have a fair guess at the guy on the sticks……

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

Actually, it's all about frame rate.

Even a minute variation in rotor RPM between the front and back rotors could produce the effect where one or other appeared to be moving in the opposite sense to actual.

Watch any film or video of a helicopter in flight and it's very difficult to discern the direction of rotation from successive frames.

-would cause complete destruction of the aircraft!

Senior Pilot - Spot on ! - it's only the slowed down frame rate which produces the visual oddities. Shown at correct speed, it is (frighteningly) realistic and demonstrates an almost unbelievable level of stupidity by a (supposedly) professional airman.

In run-up to GW1 had one of those flying very low over my meadow.

It has got to be real. But still has me stumped that I can see no evidence of rotorwash - no dust, litter or gear flying - bizarre

Given that it is a military site/location, they'd be keeping the area clean anyway.

I can't make out the nationality of the Chinook, but I'm thinking Dutch, as it looks a similar set up to when they have deployed to Carlisle airport in the past.

That'll be a D model - extensively enhanced from an A :p

You're not wrong ... :\

4468 1st May 2022 11:27

I’m no aircraft recognition expert, just an ex-chinook pilot, but on closer inspection, to my eye absolutely everything about that airframe ties in perfectly with a Dutch D model. As I said, they were retired last year.

SHOULD THAT BE THE CASE….. (I may be mistaken?) It probably wouldn’t be the best advert for the organisation involved?

In general terms, these things rarely seem to happen in isolation, they generally reflect a track record. Sometimes they demonstrate a culture. The result often being depressingly predictable.

That was my point higher up - it isn't a clean site, there's open doors on iso's, tarps and fod all over the place, and even in the lengthened video, at 2x speed or at slowmo there's only a faint waft of wind noise in the microphone (about what I'd expect from a normal day on a windy site). I see nothing to suggest it's real from that, only evidence to the contrary, though I'd also say there's nothing that is 100%, just a balance of probability there.

As far as the location is concerned, this might give a clue:

Hard to make out what it is - it looks a bit like a derelict Saeta, but the surrounding don't look Spanish.

More like a T-33, I would say - and something liable still to be found on a NATO airfield here and there.

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 ‘fly past’ was flown at considerably higher speed than the slowed down video suggests. As we all know, rotor downwash trails the aircraft. The camera movement does not allow sufficient dwell time on likely areas to determine whether any downwash was present.

I still say that the helicopter having considerable right bank while not turning and tracking a straight line down the taxiway causes my BS caution caption to illuminate and the warning horn to sound.
