The FAA Telecommunications Infrastructure (FTI) operated by L3harris was built between 2002 to 2007.

That is already well within the era of IPv6, let alone "the Internet".

There's no excuse.

For something so incredibly critical in real time, I’m not sure I would want to trust the Internet.

When was the last time the Internet "went down" globally?

		Isn't using a private network like mandating using I-95 (since it might be blocked from a freak accident one day), while using the internet, with redundant paths between hosts, like allowing the traffic to find the best path?
