Even just physical infrastructure wise. Most of the ARTCCs were built in the early 1960’s and it shows. Look at what other countries have and how their ATC is run. It’s honestly embarrassing.
I joke often that if you blindfolded somebody and took them inside an F.A.A. Center, they would assume they are in a 3rd world country, not the United States. We’re talking busy big name facilities where the plumbing doesn’t work, the HVAC doesn’t work, the water isn’t potable, the stairs to get up to the tower don’t work. It’s just honestly a joke that this is the best the United States can do.
