A travel book is about someone who goes somewhere, travels on the ground, sees something and spends quite a lot of time doing it, and has a hard time, and then comes back and writes about it. It's not about inventing. ↗
Could I interrupt here, because there is an alternative explanation, which you are particularly well placed to examine. You know the argument that it is the alchemists in the laboratories who invent the sweet new kits. ↗
That's the kind of movie that I like to make, where there is an invented reality and the audience is going to go someplace where hopefully they've never been before. The details, that's what the world is made of. ↗
Having the benefit to our society, not only here in the United States but throughout the world with the amount of invention you get from having a space program, is well worth the risk that an individual like myself has to take by flying in the vehicle. ↗
