Two likely possibilities;
1) they are going to US forces somewhere (I guess one of our many "GloboCop World Tour" hotspots) where the overwater leg was more than the safe ferry range of the Apache...
2) they are going to an ally nation for demonstration purposes (Israel, perhaps?).
As was demonstrated in Desert Shield/Storm and Kosovo, the Apache is very effective but very maintenance-intensive. Whoever is going to operate Apaches must have a throughly modern army and a large pool of well-educated, thoroughly-trained technicians and mechanics. Only U.S., Europe, and Israel fit the bill IMHO. I don't believe the Chicoms could operate them for long, and Russia has got their own attack helos (some rather good ones, actually). 3rd world nations would never choose the Apache when they can have 75% of the performance with 25% of the maintenance by going with the 4-blade AH-1W (as Turkey recently decided, tossing the Apache and the Tiger out of the running).
Hughes/er, McDonnell Douglas/er, Boeing has been trying to break into the world market with a dumbed-down Apache (i.e., they provide the airframe and some basic electronics, and the buyer adds whatever sensor suite and other digital goodies as needed). But its hard to beat the subsidized Euroweenies on price, so I figure the only nation advanced enough to handle the Apache and willing to accept the stripped-down model is Israel (which has a world-class avionics industry).
My bet is they are going to U.S. forces somewhere, in a pathetic attempt at a low-profile delivery due to some sort of maintenance problem or pilot stupidity (those guys do total a bird occasionally doing something stupid). This "restricted" BS was probably just some public affairs officer screwing with the bubble-headed news droids. If the situation were really restricted, some large, take-no-BS individuals would have appropriated the news cameras and removed all recording media.
