I've seen that before. Its from a commercial. You can hear the
announcer at the end start to say something. I'm pretty sure it's been
doctored at least somewhat.

I remember seeing somewhere that it was a (large) RC model airplane. IMO
that would seem to account for the apparent physics of the bounces.

That seems like the best explanation. I noticed it says T & W Air on
the fuselage. I can't find any trace of that as a Chinese airline on
the web. But if it's an RC plane, the video must have been doctored
to add the smoke from the tires. I don't think you would get that
much smoke from an RC size plane.

Agreed.

It looks totally photoshopped to me (or CGI).

I doubt that an RC plane--or any full scale!--could plant the mains
like that and get that much of a bounce out of the nose wheel.

If the pilot was on the brakes hard and the airspeed was low enough so the
horizontal tail didn't dampen some of the motion, I think it would be
possible to generate one of these pogo like cycles.

Then the nose gear would fail...

Wel,it would almost certainly have sustained some damage. but it's
pretty hard to get it to fail.

Though this guy did..

We've seen this one before in this forum. I think the consensus was an
R/C jet that had some CGI enhancements for the commercial. A real jet
wouldn't oscillate that fast and make those booms every time the nose
gear touched down. Plus, there are no brakes on the nose gear, so
where does the tire smoke come from after the intial touchdown?

Actually, it probably would.

It's plausible that they'd smoke like that with that kind of impact. Large
tires like that take a moment or two to spin up and they get scuffed just
from normal touchdowns.

Some jets do have nosewheel, brakes, BTW, though. don't think the 320 does,
though.

If you look at the full clip at the :16 mark the nosewheel locks up
and smokes. Impossible, seeing as the A320 doesn't have nose wheel
brakes like you'd agreed. I'm curious to know what large jets do have
nose wheel brakes? The speed of the plane's bouncing just doesn't look
right.

The 727 had nosewheel brakes, for one. But I don't see it locking up,
just coming down quick. I really can't make my mind up about this, it's
driving me nuts!
I have some feelers out. Most of the guys I work with think it;'s a
fake, but most of them thought thre were WMDs in Iraq.

I would love to see someone who is good with math do some calculations as to
how many G's the front passengers and the passengers in the aft most seats
would be subjected to.

My eyeball estimate says that they would be getting a plus 15 G alternating
with a negative 15 G on the first couple bounces.

Anyone want to take that estimate on with some estimated math?

Computer animated scenes are way too easy and realistic for it to be
anything else, I think.
