Paul Allen, (Microsoft), had one of these in his main hangar. It was a two-passenger model. Paul couldn’t ride in it because of an ear condition. But since he had two pilots and an entire flight crew on call 24/7, he could send his friends up any time they wanted to fly in it. We were planning the x-mas party he’d have every year, and we were using the hangar for the first time. It was quite the event. I got to watch Paul play PURPLE HAZE for the first time there. LOL
