Don't know about the 'real thing,' but I built the kit in its presidential markings (with a full scratchbuilt cabin interior) a few years ago.
If you would possibly anticipate doing that kit scheme, be warned that wrapping the 'United States of America' decal on the stbd. side around the bulging surface detail is extremely tricky. I made a hash of mine, and had to do some not-so-subtle paint touch-ups to try to correct.
Other than that, it's an impressive scheme...and quite a sweet build, as I recall.
Cheers
