I respectfully disagree. If you are taken to a hospital for medical evaluation, speakers would normally call that a medical issue, in plain English. None of this was routine or normal precaution—a point the article you linked emphasizes:

- "Normally, once medical personnel complete their preliminary assessment, crews are flown to shore on a helicopter, then board a NASA airplane for the flight back to Houston. Instead, the Crew-8 astronauts were taken to the hospital Friday morning."

The denotation is correct, but the connotation is wrong. Most people go by connotations, so I disagree with your statement that "speakers would normally call..."

I'm saying that one person had a genuine medical issue, and the others appear to have not.
