> this has happened before, and I don’t recall any plane accidents then
ADSB (the "non-gps" radio signals you mention) broadcasts the planes location... sourced from GPS. Because of deployment requirements there are tons of sub-$2000 ADSB out boxes on the market now that didn't exist in 1999, and hardware wise they are a race to the bottom. (Edit: I also just realized the software could have been written by someone who wasn't alive in 1999).
I don't think anything is going to happen. But I also don't like saying nothing is going to happen, because that is when you get a complex failure.
