Apart from the the History section, how much of this article is in-universe?
The actual China Clipper was a Martin M-130 plane that traveled the route between San Francisco and Manila, Philippines via Honolulu (Hawaii), Midway, Wake, and Guam. The Pacific Clipper was a Boeing 314 seaplane that traveled from San Francisco to New Zealand via Hawaii and other stops.
Is that actually referenced in-universe or is it from From Star Wars To Indiana Jones - The Best of the Lucasfilm Archives which would make it behind the scenes info? Vetinari (Appointment) 22:19, 23 February 2009 (UTC)
