Any Aircraft Buffs? First Video of F-22 Raptor

Here is the demo video for the F-22.

Fast (super-cruise*) and stealthy, and integrated avionics are cool,
but what's really impressive is the F/A-22s low speed stability and
maneuverability. In the late 40s and to early 60s aeronautical
engineers were going nuts on how to shape intakes to handle both
subsonic and super-sonic air flows, without stagnation or compressor
stalls. Supersonic in itself was a big challenge because you had to
use shock waves to slow the intake air mass to sub-sonic before it
hit the compressor blades, or they would stall. The engineers figured
it out, but the solution was keeping a lot of air going in the front
end to make sure the all hot air kept going out the back end. As you
watch this Mach 2 airplane suspend motionless in air and do tail
slides, be aware of the truly amazing performance of the engines and
intakes.

Some used to think the Su-27 / Su-31 "Cobra" maneuver was the epitome
of 3rd to 4th generation fighter maneuverability. That snap maneuver
doesn't hold a candle to what this two-dimensional vectored-thrust
fighter with fat independent horizontal stabs can do at low speed.
There must be far more tricks up its sleeve in the high subsonic
dogfight speed range.

The video is about 5 minutes long but the last 30-40 seconds are priceless.

ACC recently approved the Raptors new DEMO profile. This was the
first show. Five minute video.

Watch the elevators of the airplane in this demo. They work
independently. It also has vectored thrust.

ACC = Air Combat Command (for the non-Air Force folks)

*Supercruise: The F/A-22 can sustain supersonic flight without the
use of fuel-gulping afterburners.

Very impressive indeed. Bet those pilots don't eat a big meal prior to strapping themselves into surreal machine.
