Is this for real, or has this video been manipulated??

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.- Hide quoted text -

I was at an airshow last weekend and the RC planes have very affective
smoke producers. They add an oil to the exhaust stream to get the
smoke.

True.

But, as a general rule, RC smoke systems inject oil into the
muffler and the smoke comes out of the exhaust system, not
from the wheels making contact with the runway.

I'm not saying that they couldn't have run smoke from the
engine down to the front wheel of the aircraft in the video,
just that it seems highly unlikely.

From 11 years of flying RC aircraft, I am willing to bet
that there is no input that could be given to a scale
model capable of making that flight and landing that
would result in the nose bouncing up and down like that
on landing. To get the nose up, you'd have to use
elevator control. If you have that much energy in the
system, the mains will leave the ground along with the
nose.

I know LOTS about pilot induced oscillations, porpoising,
bounce-and-goes, bounce-stall-cartwheels, etc.

They may have used a model to film the airplane's scripted
movements, but the nose dance was most certainly produced
by photo-manipulation or CGI.

This was a well financed commercial for a major beer company for
television ads. I'm sure the production company had access to good
animations.

Well.....I don't think it's a very good marketing move to get a pilot
plastered enough on your product to get him to try to see how high
he can bounce an airliner. Must be from E. LA :-)
Better to do it remotely........like this ------

Damn! It shook that car APART ! ! !

That was Detroit iron, and built a hell of a lot stronger than the front of
an airliner.

Computer animated graphics, no doubt.

If you look a little more closely it appears there's not much more than
the stripped body "shell" and a rolling chassis with hydraulics. No engine
or interior or other unnecessary parts..

Right, but it still shook the whole chassis and body darn near apart. Not
having the engine or other interior parts would put even less stress on the
body and suspension.

I'd have been impressed if he had been in it.
