Be an astronaut. But as an adult it turns out I’d have been much better at designing trajectories.
I didn’t know either about the details of reentry and how they pinpoint the landing site. The video was extremely well done, if you go to the YouTube site the top comment says it well, “there is no pandering to the lowest common denominator”. I saw that it was 25 minutes long and said, “I’ll never be able to sit through this,” but it quickly hooked me and kept my interest.
