There's a video posted by the rcadmin that has the title "Real Plane-3D with thrust vectoring" that was posted on May 16, 2005.

I spent 22 years in the Navy, and had the opportunity to not only watch in RT the video you posted, I went back to the USSR and flew in a Sukhoi Su-27 with that very pilot about 3 years later. The plane shown in the video is an Su-33, a variant of the Su-27-the SU-33 can take off from a carrier without the aid of a catapult, and is HIGHLY maneuverable!

The video posted shows NO thrust vectoring-the stunts you see are strictly the skill of the pilot combined with the superior handling and abilities of the -33.

It's a good thing that American pilots never had to come up against that aircraft with a capable pilot at the controls!
