That's what everyone screaming 'funding' doesn't seem to understand here. If your failure mode for potentially hundreds of people dying is one controller over radio forgetting something, then it'll happen eventually. And has happened, there's plenty of videos on youtube of near miss radio recordings. When a plan is landing at over 100mph simple good luck can take care of things the majority of the time.

It just feels wrong that the primary form of control in 2026 is voice over radio.
