The other amazing thing I found when I was working as a Peace Corps teacher was that even young children in Ethiopia, once oriented to a familiar landmark had no trouble describing everything else they saw. They were not disoriented by the perspective of flying above the landscape as I had earlier imagined. This made aerial photographs of great use in my geography classes for explaining the concept of mapping. We actually ended up collaborating as I outlined the map of the region and they told me what was on the map.
I still have a set of about 30 of those aerial photographs. It will be interesting to see what changes have taken place in the 40 years since I was last there. Unfortunately the Google-World imagery is currently poor in Ethiopia except for major cities.
