F-22 Stuff
An ex-USAF buddy sent me this video...his comments:

> The F/A-22 is now operational, with several wings already flying in the Air Force. The JSF-35 'Lightning' is fast approaching operational, and can do much more than the F/A-22 - including literally stopping in mid-air from near super-sonic flight.
The Su-27 / Su-31 'Cobra' maneuver was essentially a 'one-trick pony' maneuver. The F/A-22, and especially the JSF-35, can stop and eat a Sukoyhan doing the 'Cobra' maneuver, plus do so much more.
And, as pointed out by some ex-F-4 Phantom drivers, ANY of these maneuvers in an F-4 Phantom would have resulted in stall/fall/spin. H. Ownby (USAFA '69)
Fast (super-cruise*) and stealthy, and integrated avionics are cool, but what's really impressive is the F/A-22's 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 all the 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.
