As a young boy, my dad often took me to the airport early on Saturday mornings for breakfast and to watch the planes take off. I was 7 when the first 707s were put in use by TWA in St. Louis. There was an open air observation deck, so you could hear as well as see. I vividly remember the first time I saw (and heard) one take off. I had no idea what I was about to experience, of course, and I was awestruck by the power of it. It looked to me like it was going straight up.
Thanks for the reminder!
