Why would they pay 196£ just for one way London to Nairobi portion to do that? Incidentally, that equals $5,797.29 in current dollars, for one part of the trip, one way. So you are suggesting that a church would have spent over $11,000 (anyone find the price of the Honlulu to SF to New York to London portion?) to have her give birth in Kenya for an unclear reason?
Back in those days, 1961, the tax rate was 91%, and more if added state income taxes. Obama Sr. was being sponsored by people like Harry Belafonte and Sidney Poiter behind the Foundation. Sooo, a plane trip would have been deductible and only cost the rich supporters maybe 2 cents on the dollar. I did a Internet Article on this. This does not mean this is what happened, it just means it would be financially possible in opposition to you saying it is not financially feasible.
charter aircraft would probably cost around $400 in 1961 for Hawaii to Kenya. Ship much less. How did Obie and Mama get to Australia? Who paid for that? The many trips to Indonesia?
The book Born Free had just come out in 1960 and the subjects were to be returned to the wild of Kenya.
Since Hussein Sr was a Kenyan Tom Cat, perhaps Hussein Jr's mom thought he/she should be returned to wild when born and sold the idea to a church?
How much was a flight from Hawaii to Seattle and a car rental from Seattle to Canada?
What makes you so sure she flew to Kenya? Ship?
