If you've never seen the movie October Sky, rent it. I just caught the end of it on TV, having seen the full movie years ago, and I was again choked up by it. It's a touching story, starring Jake Gyllenhaal as Homer Hickam, a young man interested in rocketry at a time when the American rocket program was in its infancy, along with the always excellent Chris Cooper as his tough, coal miner father and Laura Dern as the teacher who supported and inspired Homer and his friends.
I won't try to rehash the whole story here. I'll just repeat that it's a great film. Watch it!
