As a kid when I was living in Colorado Springs we were in one of the approach patterns to the airport there (the runways at the airport were shared with the base). One of the orbitters came in on the 747 one day (although I can't guarantee it wasn't the enterprise, it's been quite some time), and they litteraly flew right over my house, at a pretty low altitude. Just absolutely magical to watch. You could see it sitting on the runway in the distance from our top floor (also had an SR71 that made an emergency landing once that sat out away from things on the runway that we could see once).

I guess the reason it was there was the commander for an upcoming mission had a son at the AF academy, so somehow they swung bringing it through. (Unfortunately, said mission was the Challenger. The son was someone we'd actually had at our house a couple of times as part of the sponsoring that faculty members would do for cadets at the academy.).

It's been many years, but I still remember watching it fly over. Seemed like you could just reach up and touch it.
