The two passengers cited in the article are obviously severely mentally unstable (biting other passengers, threatening to hurt a flight attendant trying to help them, wanting to open the door in mid-flight … really?). Of course they need to be restrained and fined but they shouldn’t be lumped in with unruly passengers who know exactly what they’re doing and are 100% responsible for their actions. Unfortunately mentally ill people are no longer hospitalized or confined where they can’t hurt themselves or others, which of course is due to “enlightened” policies that germinated in the 60s and have been causing us no end of trouble ever since, including being partly responsible for the epidemic of homelessness.

To endanger crews’ on board an aircraft is just the pits in disgusting behaviour.

When airfares’ decreased, it gave the bus travellers’ the ability to be transported faster to their destination.
Unfortunately, common sense is lacking in most of these people.
Add Covid, & you’ve got the perfect storm of stupid.
