It's hard finding good reference photos of the British Sky Aircraft Carriers, however. I searched all over the web and this one from the site listed above is the only pic I could get.

But you can download a free Sky Captain PC game- which isn't great- but allows you to fly through New York and land on the Sky Carriers- its sort of like a Flight Simulator beta. You can make screen captures from that!

I guess the people who made it how to get the complete rights to a full-blown game version...
