I remember reading somewhere that US airspace is designed to make as much space “free” as possible which makes ATC a nightmare. Whereas everywhere else in the world it’s basically “if you aren’t landing, taking off, or doing a dumb light aviation practice circle, then you aren’t allowed”

Couple that with the ability of the military to just pretend laws don’t apply to them and this was always going to happen. Heck every other week a Blackhawk goes down they seem to be keeping Sikorsky in business.
