This is the approximate location of the aerial photos in the Sudan gallery.  It occurred to me to take a photo of the airplane's location system after I took the photos, so it was the last photo I took.  The shots were spread out over 20-30 minutes prior, off the port side of the aircraft.  Bangui is the capital, and the Ubangi River it sits on is the southern border of the country with the Republic of the Congo to the south.
