Based on https://globe.adsbexchange.com/?icao=a835af&lat=34.178&lon=-119.169&zoom=9.5&showTrace=2022-12-13&timestamp=1670902710, Elon's jet has a PIA hex code (which obfuscates its identity) but was using its tail number (which reveals its identity) for a call sign? Am I misreading this?
ADS-B Exchange - track aircraft live

ADS-B Exchange - track aircraft live - aircraft flight history

In that case the argument that non-public data was required to track its flight (in this case, at least) is just patently untrue?
Is this all just ludicrously stupid?
It's been pointed out that I did misread, but in the funnier direction. It wasn't using a PIA hex code (you can look up N628TS on https://registry.faa.gov/aircraftinquiry/Search/NNumberInquiry), so literally no identity obfuscation.

@mjg59 even if he was using a PIA, any airport you’ve heard of has a local plane spotting community of people with cameras and telephoto lenses. They’ve been doing this longer than the modern crowdsourced ADS-B communities. Combine those datasets and it is very hard to be hidden in the skies unless someone is using a rotating series of rental jets
@sigmafactor @mjg59 Or just a jet card, like you know, most rich people do.

He’s definitely a dumb guy’s idea of a smart guy, and also very dumb himself
@sigmafactor @mjg59 I mean, honestly, I can see the attraction of taking private flights, even if just to avoid COVID exposure. buuuuuuut, if I was going to do it I'd absolutely use NetJet or whatever rather than buying the damn plane myself. Jet planes are propelled by burning huge amounts of money, which reduces the money pressure in front of the plane causing it to move forwards.
