They’re called broken arrow incidents by the US government.

The Russians have a list as well.

The US has almost detonated a hydrogen bomb over the US state of Georgia. The plane had to ditch its bomb due to an engine issue, and all but one of the lockouts failed.

The Cold War was a nutty time, both sides had enough nuclear armed planes flying to decapitate the other side at a moments notice. Accidents were bound to happen.

There’s also been incidents on both sides where launch detection systems have falsely identified nuclear launches, and only the intervention of a few people prevented a retaliatory launch.

Nukes are stupid.

You’re giving me flashbacks to the online training my work makes me do every year.

I almost failed the first of 7 courses because I made the mistake of trying to do actual work while listening to the training, and didn’t realize there was a 5 minute timer for inactivity on the video player. And no, there was no additional time provided to complete the training. It was mandatory but essentially had to be done on your own time.
