I gotta call BS on this line nerdery. The space station is still actually not completely out of the atmosphere. Anything less is just somebody picking a level with a difference and claiming authority. Notice how important the physics must be when they round off the level to the nearest mile or kilometer.
If we’re going to claim authority, I’ll listen to somebody who paid his own way over 50 miles and then says it didn’t feel like outer space to him. All the professor’s and other wannabe’s can sit on the ground and act as smug as they like. I’ll pay no attention. There’s always another line.
