Smaller and smaller planes

We flew from Kigali in Rwanda to Dar Es Salaam in Tanzania in a propeller powered plane. This is not the first time that I fly in a propeller powered plane, but it is not a very common experience either.  

When I took a photo of the propeller in mid-flight, the result was a bit unnerving. The propeller appeared to have frozen.  How can the plane fly when the propeller is not rotating?  The photo, of course, was the result of the very fast shutter of the camera.  The fast shutter captured the image of the propeller in such a short period of time, during which the propeller hardly moved.  

Later, when we flew from Dar Es Salaam to Iringa, we flew in an even smaller plane.  Seats were not assigned.  I found myself seated behind the co-pilot, which, for the first part of the flight, was not occupied.  

In the middle of the flight, the pilot had his hands folded in his lap.  Who was flying the plane?  The auto-pilot, of course.  Still, it was a little unnerving to see that seemingly, no one was flying the plane.  

Those were interesting experiences.
