Discount Tire Company flies/flew one for the longest time out of SDL. Great jet.
Flew. And OMG was it pristine. The first airplane I ever saw, and actually got chills. Still remember the smell of her, also. I went home that night and... nevermind.

Anyways, I actually met the ex-wife of Bruce Halle, and when she told me who she was, I said, "OMG! You guys flew that JetStar!!" At Blue Martini. With no drinks in me (I was bellied up getting my 1st one). True story. She smiled at me and said, "I don't even know you and I like you." We ended up talking about that airplane for about 45 minutes. She did all of the interior, the layout, design, etc. I remember her talking extensively about the pillows, and the carpet.

Said it was her favorite airplane in the fleet, even after they got the Falcon.
There was another one that flew out of SDL many years ago that had an HF antenna that it flew behind it. Recovering it always required a runway closure until they got it wrapped up and secured.
I am a HUGE fan of that airplane. If they were still around, it'd be one of those that I'd figure out a way to get into.
