Optical Illusion

This morning, I took the boys to a park. As they played, we heard a plane passing overhead. As he usually does, Matthew screamed and jumped and pointed. "Airplane! Airplane! See dat mama? See dat Didi? Airplane!" Then, to his horror, he saw that the plane was headed right for the moon, still visible in the morning sky. "Oh NO!" he cried. "Airplane! Watch out for da moon!"

It was a close call, but the plane and the moon some how missed each other.
