Revolution VR.

VR = Virtual Reality.

From the Internet web site Strategy Page courtesy the tip from Bayou Renaissance Man.

"Technology changes the game - air warfare edition"

 "Strategy Page notes that (relatively) cheap virtual reality (VR) technology is revolutionizing how combat pilots are trained and made combat-ready."

"virtual reality: noun - - A computer simulation of a real or imaginary system that enables a user to perform operations on the simulated system and shows the effects in real time."

As extracted from the Strategy Page article consider merely the cost of VR as a means of training the TOP GUN type fighter pilot in the modern age.

"New technology has made flight simulators a lot more effective and cheaper. Until a decade ago, a realistic combat flight simulator cost about as much as the aircraft it was simulating. While that did reduce the cost (per 'flying' hour) of pilots practicing, it was not enough of a savings to make it practical for less wealthy countries to get these simulators and use them heavily."

"The new generation of simulators cost up to a tenth of the price of the aircraft they simulate. Suddenly, countries like China can buy dozens of simulators, and give their pilots enough realistic training to make them a threat in the air, especially pilots from countries that have long spent money for lots of pilot flight time." 

NOT only cost I might assume but virtual reality much more "real" than a decade ago.
