Yes I read your post. It’s pure speculation. There could be any number of resaons for being in Mombassa. Your hypothetical is a strawman that you posed and expect others to explain away.
Of course it’s speculation. This is all speculation. I simply asked a question about something that doesn’t make sense to me. Leaving aside the very big issue of taking an international flight of many hours duration while very pregnant. In 1961. That also makes no sense to me.
