Makes sense. CNN reported that international airlines were still departing for North Atlantic flights, apparently because they use a separate communications system.

Yeah, oceanic flights largely use satellite-based CPDLC today, or HF voice as a fallback, but not VHF in any case (which I suspect is the implicated system here).

VHF 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.

		Sorry, typo, I meant VHF (i.e. voiceband), of course. VORs are indeed for navigation, not communication. Updated.

They’re under socal departure (or equivalent) until handed off to - well, nothing. So no need for intercommunications.

I'm stuck at SFO and a flight for Hawaii just boarded perhaps 20 minutes ago. I don't think it has taken off yet though.

If you're flip your claim via edit it's usually polite to do it via addition rather than revision so the other replies still make sense/don't get downvoted by confused people.
