I recall a SF story from probably 50 years or so ago where someone had to make a suitless trip between two airlocks in space. According to the story (iirc), they survived.

I remember a few slightly-more-recent examples, though I don't remember where I read them! I _think_ Seveneves had one instance, but that's not specifically what I'm remembering.

The episode of Star Trek: The Next Generation where the doctor and engineer are trapped in a cargo bay with burning toxic fuel is, oddly, one of the most "hard science fiction" scenes in the whole show. They decide, given everything on the ship isn't working after a disaster, that they must vent it to space to extinguish the fire, and they have to do so manually, and without suits.

So they hyperventilate and exhale as hard as they can. Brace themselves against a support. And then they pop the door. Their hair and clothes ripple as the air rushes out. They get dizzy and have about ten seconds of useful consciousness to start the re-pressurization process. No exploding heads, no instant death. Just a torrent of air and then frost creeping over skin during a profound silence as the seconds run out. Accuracy turned out to have better drama, for once.

The Expanse got this right, as well. Early in the series a Belter is shown casually opening his helmet to fix a loose wire after exhaling and dropping his suit pressure.

My dad had a friend that worked at the Johnson Space Center who gave me a private tour many years ago. He pointed out the room sized, high vacuum, spacesuit test chambers and told me of a startling incident that happened once in one of the chambers.

While walking around in the chamber, a tester had walked too far and had accidentally pulled the umbilical tubing from the wall. He was at that moment exposed to a hard vacuum (equivalent to that found in outer space). The safety observer immediately started emergency pressurization and the tester survived. He continued to work for NASA and ended up being in charge of safety procedures.

So you're saying _Event Horizon_ took rather unrealistic liberties?

No, he inhales before rising the visor and exhales before closing it, so it is actually not correct.

It was also not the last time they got it wrong https://www.youtube.com/watch?v=f2WcVXf7Iz8

At least they are consistent.
