Air pressure can do amazing, spectacular, catastrophic things when the vessel holding it decides to let go at once!
Exactly. That is why in industrial situations some pressure vessels and piping are hydro-tested using water pressure, not air pressure. If a failure occurs during testing, it may crack or even break apart but it will not explode with catastrophic results as with air pressure. ;)
