Pregnant Stanley Ann and Barack Sr traveled to Kenya to get Hussein Onyango Obama’s blessing. The blessing is denied. Stanley Ann plays the statuary rape card. She threatens to charge statuary rape charges if Hussein Onyango Obama does not pay for her education. Hussein Onyango does not want Stanley Ann attending the same university as his son. They agree to send Stanley Ann to the University of Washington. This would separate Stanley Ann from Barack Sr so he could concentrate on finishing his degree at the University of Hawaii and get Stanley Ann back to her home town, Seattle. There is one more hurdle: The airlines (possibly British Airways) would not allow a woman that far along in her pregnancy on board the plane. She would have to stay in Kenya and have her baby in Mombasa. Two weeks later, she takes a plane to London (my theory) and from London, over the Polar route, to Vancouver BC. At that time, the international airport in Honolulu was just being built, and Stanley would not have been able to fly directly from Kenya to Honolulu, but only through Seattle. She takes the ferry from Vancouver BC to Mercer Island where she is taken in by her childhood friend, Susan Blake. Stanley Ann does not fly back to Hawaii from Seattle. She stays in Seattle to take courses at the University of Washington, subsidized by Hussein Onyango Obama.
