These four pictures are admittedly not sharp at all because I simply don’t know how to photograph a moving target, especially one coming right at me at high speed, but Challenger put on such a show for us, flying back and forth down a very long corridor four or five times, that I wanted to show what it looked like. There was a handler on either end of his path, and he was rewarded with a treat each time he landed on their arms. The guide said that was his food ration for the day.
