Two years ago, my wife woke me up and said "You have to see what's on TV."
Later that day, I walked my oldest daughter in a stroller to her second day of preschool. The sky was blue and clear and had no planes.
Today, that daughter is walking on her own feet to kindergarten. She walks with me (and her younger sister) up the same street I walked to kindergarten at the same school 29 years ago, past many of the same houses. I'm not sure, but I think her class is even in the same room mine was.
The planes, as they were in 1974, and in 2002, are back in the sky.
