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.
They’re clearly not “jumping” they’re pushing the earth away
That’s relatively true
