First Man (2018)
Kyle Chandler: Deke Slayton
Deke Slayton : Why do you think space flight is important?
Neil Armstrong : I had a few opportunities in the X-15 to observe the atmosphere. It was so thin, such a small part of the Earth that you could barely see it at all. And when you're down here in the crowd and you look up, it looks pretty big and you don't think about it too much. But when you get a different vantage point it changes your perspective.
