The first of these occurred in 1962 in Niger, where I went after finishing botanical field work In Burkina Faso (then Upper Volta). A mining company offered me a plane ride from In Abangarit in the Sahara desert, which I had reached by truck, back to Niamey. We flew over the medieval Islamic Tuareg city of Agadez, a caravan passage center notable for its mosque (center left on photograph).
Another flight was offered by missionaries in Liberia after I had photographed Kpelle tribal life for a textbook company. I photographed two Kpelle villages, one village next to the Saint Paul River.
The third occasional flight was in Gabon, where I took a short flight around the capital Libreville. On this flight I photographed floating logs ready for export in the harbor, witnesses to the destruction of the African rainforest.
