I've watched videos from HUDs of several planes where you can SEE the G meter hit 11, and in one case 12, and the pilots were clearly heard grunting, and in at least one talking still.

Seekerof: I did not know that they had the new G suits. But after reading on them it just helps with the fatigue of the turn. which probably means the pilot can go in and out of turns quicker without neding time to catch their breath Just because they don't have to flex all their muscles. I didn't see anything on being able to take more G's
Meanwhile, airplanes have gotten even faster and more adept at maneuvering. The increased agility of such advanced models as the F/A-22 Raptor means that a pilot will be subjected to higher g forces in sharper dives and turns than ever before. Extremely rapid acceleration means that G-LOC may come on virtually instantaneously, without any of the useful warning signs such as grayout. Thus, the well-dressed Raptor pilot will don several new pieces of gear. A face mask called the Combat Edge forces pressurized air into the pilot’s lungs to make the grunting maneuver more effective and less tiring. And the old “speed jeans” have been updated as the Advanced Technology Anti-G Suit, or ATAGS, which completely envelops the legs and buttocks. A pilot wearing both the Combat Edge and ATAGS can withstand rates of g onset faster than 5 g per second.
Pearson told Air Force Magazine, “We have cleared the entire [flight] envelope out to Mach 2 ... up to about 60,000 feet” and at nine Gs of maneuvering.
The F/A-22 has been tested to high angles of attack, at sustained nine-G turns, and has turned in a staggering performance in acceleration and speed. It will easily outmaneuver any other airplane in the world, Pearson said. Thanks to its stealth, it likely won’t have to.

There was recently a show on discovery that took the Raptor from conception in the 50's with other types of aircraft, to the YF -22 and 23, and the changes that have been made to the F-22 since Lockheed was awarded the contract.
I saw that show also. It was very interesting. You could also tell how badly they were kissing up to the plane. The way they made it sound is that there is not a single flaw in the plane. Sounds to good to be true to me.
It was one F-22 against eight F-15's. One of the F-15 pilots said he thought he had a visual and then lost him. The next thing he knew the raptor had buzzed his canopy. But what happens when the raptor fights another stealth plane. It will go to WVR. It should make for an Interesting case

The longer the wavelength of the radar the shorter its range, if you want a radar that can detect stealth know that it will have about a 20 mile range.
Thats not strictly true , as the serbs used old P-12`s to track an F-117a using the `black hole` method.
The Sukhoi OKB has had plenty of ideas for next-generation fighter aircraft, for example a single-jet lightweight with the general configuration of the Su-27M but about half the weight, in the class of the US F-16 fighter. Sukhoi has displayed a model of this concept, designated "S-54", at international airshows in recent years. More significantly, the organization developed a new experimental prototype aircraft, the forward-swept-wing Sukhoi "S-37 Berkut (Golden Eagle)".
In 1983, the Sukhoi OKB began work on a heavy fighter designated the "S-32", with a forward swept wing, as a parallel effort to work being done by the MiG OKB for next-generation fighters for the 1990s. The Soviet government decided to emphasize the MiG efforts, but allowed the S-32 work to continue on an experimental basis.
With the collapse of the USSR and the following economic woes, work on the S-32 had to be suspended, but as the Sukhoi OKB began to make money from foreign sales Mikhail Simonov decided to continue the project with company funds. Due to security concerns, the S-32 became the "S-37". The type made its first flight in September 1997, with Igor Votintsev at the controls. The S-37 has been run through a sequence of flight tests, with the Sukhoi OKB receiving some state funding for the effort.
While details of the S-37 remain classified, it has flown in public demonstrations. It is of size and general configuration similar to that of late-model Su-27 variants, though of course noticeably different with its forward-swept wings. Although forward-swept wings have traditionally had problems due to excessive structural loads, the S-37's wings use advanced composite materials to give them the necessary strength.
The S-37 has a wingspan of 16.7 meters (54.7 feet), a length of 23.8 meters (78 feet), and a normal takeoff weight of (56,600 pounds). It is powered by two Aviadvigatel "D-30FG" afterburning turbofans, similar to those used in the MiG-31M, with 252.1 kN (25,700 kgp / 34,200 lbf) afterburning thrust each. It is an inherently unstable aircraft that is kept in controlled flight using a fly-by-wire system, something of a tacit admission that the dynamically unstable approach has its virtues. Interestingly, the Berkut is so large that its wings fold to allow it to fit into Russian hangars.
* In the spring of 2001, Sukhoi officials announced a collaborative program involving Sukhoi; all of Russia's aviation research institutes; and many of Russia's aviation industries to develop an operational next-generation fighter, under the "Future Air Complex for Frontal Air Forces (Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsyi / PAK-FA)" program. A collaboration between the MiG and Yakovlev concerns also developed a proposal.
In late April 2002, the Russian government announced that the Sukhoi-led group would build the PAK-FA, though the MiG-led group would be given some share in the program. Sukhoi later announced that the aircraft has the company designation of "T-50". The T-50 will be somewhere between the size of the MiG-29 and the Su-27. It is expected to compete with the American F-35 Joint Strike Fighter (JSF) in export sales, and eventually probably in air combat. The schedule for the T-50 is very ambitious, with initial flight of a prototype in 2006 and introduction to service in 2010.
Simonov stated that the new Sukhoi fighter will be a multirole aircraft, and would be able to operate from aircraft carriers as well. Sukhoi officials insist that the S-37 is not a prototype for the PAK-FA. They emphasize that the S-37 is strictly an experimental platform, but add that its technology will be leveraged into the new design. Sukhoi has also engaged in discussions with India on a partnership to help develop the PAK-FA. The Sukhoi group has provided India with data on the S-37, and has obtained India's requirements for the new aircraft.
While the MiG OKB was working in a "step forward step back" fashion on second-generation MiG-29 concepts in the late 1980s and through the 1990s, they were also working in fits and starts on a true next-generation fighter under the "Multirole Tactical Fighter (Mnogofunktsionahll'nyy Frontovoi Istrebitel / MFI)" program.
The MFI program had been initiated in 1986 to counter Western efforts to develop next-generation fighters, such as the US "Advanced Tactical Fighter (ATF)", which would become the Lockheed Martin F-22 Raptor. The MiG MFI design team was originally led by Grigoriy Sedov and later by Yuri Vorontnikov.
Initial MFI prototype construction began in 1989, with the prototype, the "MiG 1.44", finally rolled out in early 1994. It performed taxi trials later that year, and then the program finally bogged down to a halt and remained in darkness for the next several years. Rumors circulated in the West about the secret "MiG 1.42", along with speculations about its features.
However, work on the MFI was only dormant, not dead, and the type was finally unveiled in January 1999. The designation was announced as the "MiG 1.44", the MiG 1.42 code apparently having been only for the overall development program.
The MiG 1.44 looks something like a child of the MiG-29 and the Eurofighter Typhoon. The MiG 1.44 shares the Typhoon's canard layout, an unusual configuration by Russian standards, and the twin underslung engines. In general style, however, it clearly says "I am a MiG!", and by no means a Eurofighter copy.
MIKOYAN MIG 1.44:
A group of Russian industries led by Sukhoi and another group led by MiG and Yakovlev competed for the PAK-FA contract, and in late April 2002, the Russian government announced that the Sukhoi group had won the award. The government specified that MiG and Yakovlev would get workshares in the program, but the loss of the competition was still clearly a blow to MiG.
It may not have been a major blow. The VVS does not actually seem to be interested in procuring the PAK-FA in numbers any time soon, with upgrade of their existing aircraft remaining their top priority. Some observers believe the PAK-FA effort is being conducted by the Russian government to keep their aircraft industry up to date and attract foreign investment. The MiG organization may have lost this battle, but it is by no means certain they have lost the war.

Do you really think pilots wouldn't say the raptor is the eight wonder?? they have to say so to make people think that all the budget spent is the raptor is well used because, well, there will be four or five planes but, jesus, they are impressive! And they are not really free to say what they really think, their job is in game and if they even try to say "well, the raptor is good but just a little more than the eagle" they will leave their actual job faster than a SR71
So, please, stop talking about pilots and all that, ok? they say what the people who pay them want them to say. I'm so tired of reading all that stuff... at least the article that started the post, even if it was outdated, was a fresh opinion that tried to say that not all glitters are gold
