I guess your AEO was flying in a modified Neptune to give it a 3 Day flight duration.
Here is an interesting narrative on the Truculent Turtle (Neptune P2V-1) historic flight from Perth Australia to Columbus Ohio in 1946 ... some 11,236 miles taking 55 Hrs 17 Mins NON-STOP
Historic Neptune P2V-1 Non-Stop Flight
The record established by CDR Tom Davies and the crew of the Truculent Turtle stood for decades. The distance record for all aircraft was broken in 1962 by a jet-powered B-52. The Truculent Turtle’s record for piston/propeller driven aircraft was broken by Burt Rutan’s Voyager, a carbon-fiber aircraft, which made its historic around the world non-stop flight in 1986... more than 40 years after the Turtle landed in Columbus, Ohio.
