The military has been building flight-simulators since World War II. But, mostly, those pilots-in-training have flown alone, because full-motion simulators are so expensive. That may be starting to change, thanks to a good-enough-for-testing, NATO-backed sim which lets pilots "learn to fly together even when they are stationed thousands of miles apart."

Of course, the ability to give a pilot all the information he needs to carry out his mission almost instantly across thousands of miles can have other implications," the Register notes. "It's already quite normal for pilots handling remote Predator drones over Iraq or Afghanistan to be sitting in a comfortable base near Las Vegas... The very technology which Qinetiq and the RAF are using to train pilots may soon make flight personnel largely obsolete."
