Did the Starship launch today just ground all flights in the USA? Maybe, maybe not. I am convinced it did. If Elon Musk can take a shred of evidence, or just make shit up, and change domestic and foreign policy, then why can't I?
We obviously live in a simulation after all, what does it matter?
how would an upcoming launch cause this?
