Just a couple of comments on Mr. McHenry from the peanut gallery...
The Shack was hosted by the CAF at no cost to Air Atlantique (see comments on $$ cost of ramp space, not to mention hangar space).
Keeping the aircraft "properly maintained" would have entailed a full-time maintenance guy. What Gary was able to do was, I believe, gratis on his and the CAF's part. With the only "permanent staff" being Gary and the "long-suffering" Mark having to take care of 927 and FiFi, plus the constant shifting of aircraft due to hosted events, I think would have been asking way too much.
Keeping the aircraft clean? Well, for one thing, there's not an EPA-approved wash area at Midland large enough to accomodate the -24 or -29, much less the Shack. And dust is a daily problem at Midland.
From earlier conversations, plus info from a couple of articles in FlyPast, both the engines and props on the Shack are very near their overhaul times. Since the cost of prepping, then flying it, back to the UK would be REALLY expensive (plus the fact that it wouldn't fly again there), finding a suitable home in the US where due care would be available makes sense.
Having a home a Pima, in conjunction with other Cold War platforms would also make sense. And Mr. Mc H is (if you haven't seen the interior) is on of the few COMPLETE examples of this generation of aircraft (Laso having been active with the RAF until 1981, I believe).
End of peanut gallery comments....
