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.

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.

Actually, it probably would.

Plus, there are no brakes on the nose gear, so where does the tire smoke come from after the intial touchdown?

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.
