Sorry but I call fake...... We don't have large breast to run wings like that.

Looks like the ultimate work out. If you fail you can die. Can you imagine the Wright bros? "Dude... we gave you the plane for a reason"

Fake. I don't know anything about flight, but I do know about working out, and I can tell you that the rate at which he's lifting his body weight about 28-24 inches with each thrust at that level of arm extension isn't a real thing.

At 0:21 the guy on the left starts running towards the camera. At 0:19 he's on the other side of the wing, and somehow he manages to run nearly trough the wingtip without clipping it. He also manages to cast his full shadow on the wing while his leg is still on the other side...
The shading on the wings does not match textile material as shown in the closeup, it's too reflective.
The guy would need to run really hard to get decent takeoff speed, yet he's wearing one of those squirrel suit things with textile between the legs that would make running really awkward.
The wings do not look fully loaded, loose textiles like that would billow and flap quite a lot under the load of a fully grown man.
Of course a picture perfect landing on the first attempt.
The climb is substantial, yet the airspeed is low. No bird manages that kind of climb by just waggling their wings a bit. They have to work really hard to get off the ground and gain speed.
The wide monowing design would be extremely unstable. No apparent stabilization mechanism is evident.
At 0:41 having attained an airspeed of about 2m/s he folds his legs back (however he does that). But the main point is, his legs would represent air-resistance which would would make him pitch down, so folding the legs up removes one force for pitching down. Moving the legs up also moves the center of gravity back, which would pitch up. But somehow he keeps straight on and doesn't just pitch up. Which is physically impossible.
The wings represent a lever about 2-3 meters long each. They are hinged on joints to motors about the size of a teacup acting on them on a lever about 10cm long. That is a lever ratio of 30:1, so each wing carrying half the average weight of a man (say 70kg) would translate to the equivalent of 2 tons at the end of the 10cm lever. So each of those servo motors is supposed to be able to pick up a load of 2 tons in a matter of fractions of seconds.

I also notice janky frame transitions. When he landed, the camera began stuttering only on the "Flying Machine." Motion blur was extremely noticeable as well. I think shopped? thinking.gif

I also can tell you didn't read the article either. Or follow any of this thread, as you would then know they used motors.

Agreed.

And with hang-gliders, and the device in the article, this is where gravity comes in.

There is a downward slope in the video where the flapping wing thing takes off, it's just a more subtle gradient.

If the flight is real, I think he's trading air speed for altitude, maybe with a little forward push from the flapping, then angling down to land.

Thermals aren't the only way to gain altitude when gliding, but yes, you do need moving air.

It's not man powered, there are batteries and electric motors in the backpack.

Guys and gals, it's fake.

The experts have spoken AND demonstrated it's a fake: http://gizmodo.com/5895235/cgi-experts-say-flying-bird-man-is-fake

If you only want the essential, look at these two videos: the first is preceded by "Emphasis added. Martin even produced a smoking gun:", and the second is the last video which is preceded by "Update 2: Another heavyweight CGI alum weighs in:"

In this video you can clearly see that the shadow from the guy on the right is clearly computer animated.


I expect him and his coleagues to be from a CG studio and this is their PR campaign.

Sorry Blameless, made tons of edits while you were responding. I'm kind of always re-reading what I write after I write it... Bad habit from school.

EDIT:
Just read the link above, this parts so true, funny it wasn't noticed earlier:
