So a question, would a Pan Am liveried aircraft working for the government still have a regular Pan Am scheme, like this below.
What sort of work would it be doing for the Govt?
Errmm ... the same things the BOAC operated Empire boats and BOAC and Pan-Am operated Boeing 314s
did for their respective governments? They also operated in passenger service during the war.
The BOAC boats operated in standard Brit cammo with BOAC markings and civil registration,
supposedly some of the Pan-Am 314s were painted in USN sea-gray top and upper-side surfaces
with civil registration. NC18612 was painted in an experimental multi-tone blue scheme.
However, in photos of 314 NC18601,
Honolulu Clipper when she was lost in 1945, she's in
standard Pan-Am silver dope with black bottom, black codes on the tail and orange wing panels.
No Pan-Am logos. BTW 18601 was the first 314.
As to the original question, the big Pan-Am globe logo is post Korean War, it was designed in 1955
for the coming jet airliners. The post-WWII delivery scheme as used on the Boeing 377, however,
would be believable on a Korean War Hercules.
