How the crew of the 60s, and 70s handled unruly and aggressive passengers

During my time as a cabin crew there were hardly any passenger giving the crew a hard time. If they dared to, they would have met with the same treatment. In the old days, there were no social media and few reporters were around to pick up stories of crew fighting back the abusive and aggressive passengers. This embolden the crew not to cowed to the bullies. There were many stories of how the crew handled the unruly passengers. I won't want to elaborate as it is not in the interest of anyone since it happened about 40 to 50 years ago.
