What’s the real cost of downtime in industries like aviation or manufacturing?

In aviation, energy, and heavy manufacturing, even a few minutes of downtime can cost thousands sometimes millions. But beyond the numbers, there’s a hidden cost no one wants to calculate: the pressure on teams, the delayed maintenance, the lost data, the silence of a production line that should be alive. Downtime isn’t just about money it’s about momentum, trust, and the rhythm that keeps everything moving. I’m curious how do you define or measure downtime in your world? What’s the real impact when everything stops, even for a moment?
