Hmm, I think this logic kinda fails because if astronauts are “not on earth”, then neither are air travelers.

Astronauts orbiting earth are just couple kilometers higher altitude

I mean 30,000 feet is 9km. The Kármán line is 100km. The ISS is at an average altitude of 400km.

It’s a bit like saying people in planes don’t count as flying because then people on trampolines should count.

Are you saying that people jumping ARE on earth? Because I disagree.
Are there enough trampolines on earth that we could reasonably expect that at any time there is at least one person in the upper part of their jump on a trampoline?
