The U.S. military has a ton of low level training routes where fighter and attack pilots go to train for below radar operations. What's special about the Jedi transition is that it's built into the extremely rugged and mountainous terrain of California's Eastern Sierras, and it's exit is fairly accessible by road, so amateur aircraft spotters come here to take pictures and video of aircraft flying under them. In theory, you could go fly the Jedi transition yourself. While it's part of the R-2508 complex administered by Edwards AFB, it's not actually inside restricted airspace. I have to strongly discourage that. You'd be operating in a busy MOA, below radar, below surrounding terrain, on a route trafficked by aircraft moving much faster than you, at density altitudes usually exceeding 8000 feet... but it would be fun. In the meantime, check out this video.
