Wasn't there an episode on "Young Sheldon" where he mails a notebook to NASA then later shows a NASA scientist how to land a first stage rocket back onto the ground so it can be reused, saving hundreds of millions of dollars?
Musk has a cameo at the end looking at young Sheldon's notebook then putting it back into his desk when someone is coming.
Always wondered what else was in the drawer, though.
