Or having mandatory security checks in place after frequent accidents on supersonic planes is bad...

The aviation industry must be one of the most regulated ones and it's entirely necessary to guarantee the safety of passengers and crew. You don't see anyone complaining about it except Boeing who failed QA in the past couple of years and killed some hundreds of people due to their oversight.

Perhaps if the industry had been allowed to develop, we'd have some freaky ass new and innovative tech that would've abated the problem. The world may never know!
