Makes sense. CNN reported that international airlines were still departing for North Atlantic flights, apparently because they use a separate communications system.
replyYeah, oceanic flights largely use satellite-based CPDLC today, or HF voice as a fallback, but not VOR in any case (which I suspect is the implicated system here).
replyVHF Omnirange (VOR)[1] is unlikely to be involved. VOR stations are not dependent on a network. All they need is power. It's 1950s technology. The big ring of antennas next to US 101 just north of SJC is a VOR.
replyI saw one!
