It's very rare to see a 707 flying these days, and whenever I do see one, it brings back very good memories of my childhood. The very first jetliner I remember flying on was a 707 (can't remember which series), and it was a flight from Phoenix, Arizona to St. Louis, Missouri back in 1964.

To me the Boeing 707 is the classic Mustang of jetliners, and it will always remain a classic for many aviation enthusiasts.
