We had ESTEC(European Space Research and Technology Centre) sitting at spitting range from our home(of course everything in The Netherlands is within spitting range). When I was 10 or so they had open house. My dad took me to see. It was a good day. Came home with a goodie bag. Pictures of astronauts and planets adorned my room until I entered Highschool. Most impressive was the landing capsule which looked cramped even to a small kid, and the Ariane exhaust pipe we could walk under, was downright scary.
