One day I took a friend's son up for a flight in my Cessna 150. As we flew around the area, I explained, "One of the things we have to do is look out for other airplanes."
As I was scanning the skies, I found a plane off in the distance and pointed it out to the young boy. "Do you see the plane over there?" I asked.
"Yes," he replied. "Is it one of ours?"
