I recently drug my whole family into the yard to watch the ISS fly over on a crisp clear night. The app said where it would appear, and that it would disappear at about 70 degrees after passing over, and like clockwork it faded and disappeared. That’s some pretty impressive math right there.
As far as the shuttle goes, I never got a chance. I did see one of the Space X launches this summer on a trip to Kennedy. We didn’t make it in time all the way out (early morning) but it was beautiful from our Titusville hotel lot. They didn’t land the stages, though.
One more thing...on the tour of Kennedy, the Space shuttle was awesome and huge and cool to see...and then you see the Saturn V from the Apollo missions, and my jaw hit the floor. Holy cow, they put that giant skyscraper into space. My hats off to those 1960s scientists and engineers, and those crazy guys who sat on top of that thing. Wow.
