After a Space Shuttle astronaut threatened to not come back unless he had more time to work on his experiment, NASA put a padlock on the airlock door and only the mission commander had the key. - eviltoast
What happens when an astronaut in orbit says he’s not coming back?

"If you guys don't give me a chance to repair my instrument, I'm not going back."

On the second day of the mission, Wang floated over to his experiment and sought to activate the Drop Dynamics Module. But it didn’t work. He asked the NASA flight controllers on the ground if he could take some time to try to troubleshoot the problem and maybe fix the experiment. But on any Shuttle mission, time is precious. Every crew member has a detailed timeline, with a long list of tasks during waking hours. The flight controllers were reluctant.

After initially being told no, Wang pressed a bit further. “Listen, I know my system very well,” he said. “Give me a shot.” Still, the flight controllers demurred. Wang grew desperate. So he said something that chilled the nerves of those in Houston watching over the safety of the crew and the Shuttle mission.

“Hey, if you guys don’t give me a chance to repair my instrument, I’m not going back,” Wang said.

…

So in the immediate aftermath, someone at NASA, probably within the crew office, initiated the capability of a commander to lock the hatch if he or she felt uncomfortable about a crew member. It was used frequently in subsequent missions involving payload specialists.

      The article was in depth, but absolutely fit the bill of “interesting as fuck”.

      “Payload specialists” were essentially passengers. They had basic training but were not professional astronauts. Their main job was to perform experiments, not operate the spacecraft.

      After Wang nearly lost his shit commanders on the next few missions locked the hatch. After the complicated Apollo hatch led to … problems NASA started making hatches that were easy to open, perhaps too easy. One astronaut described it as flipping a switch, turning a wheel once, and letting all the air out. Those commanders didn’t want someone going apeshit and killing everyone. Ironically the payload specialists weren’t the biggest threat.

      They don’t make it super clear in the article but astronauts at the time we’re getting basically every drug and medicine that wouldn’t impair their work to test their effects in microgravity. On a later mission a professional astronaut had a bad reaction to one of the drugs he’d been given and had to be restrained by his crew mates from taking “drastic action”.

      TL;DR: Space is scary, yo.
