One manouver that they teach in it is inverted spins. There was one on e bay about a year ago, but it was a big restoration project. The biggest problem about this plane is it is old and their is no replacement on the horizon, so they are getting used up far more than most government things. Even though the the parts wont fit, the Citation came out of its design and old Citations are getting pretty cheap for what they are. As for the noise, with the engine idling on the ground at 200 yards to me sounds like an F1 race car stuck in your ear.
