SHIP. DOCK. SAILORS.
I see, same increment or "wave", but not on the same aircraft due to his destination being so far west, that they probably went east instead. Although there are some mighty long hops going that way. Still, it can be done, and could be done in '59. The great circle route from Nairobi to Honolulu does go east, but it goes over the former Soviet Union. However going through Hong Kong only increases the distance by a couple of hundred miles, and it makes a good refueling stop. (Nairobi-Honolulu is 10736 mi, Nairobi to Hong Kong (conveniently British at the time) is 5427 mi and Hong Kong to Honolulu is 5568 mi. Range of the Britannia aircraft, 9268 km or about 5759 mi, at least according to one source, another says 4,270 mi. Even the longer range is kind of tight for the over water leg, but one could make stops in Bombai India and Tokyo Japan to make the legs shorter, the longest would be Tokyo to Honolulu, although the overall trip even longer, but they'd probably attract more passengers. (Distances calculated by the Great Circle Mapper. A very cool tool. It's more accurate than a simple spherical earth model. (It uses the same WGS-84 model that GPS uses.)
If you can find a copy of the Susan Blake video (most have been "disappeared") She clearly states that she showed Stanley Ann how to change a diaper.
How long does it take a new mom to learn that particular art?
Think about that. What was a days (or perhaps weeks?) old baby doing 2500 miles away from home? What new mom would subject her infant and herself to such a hasty journey unnecessarily?
What necessity drove that trip?
