144 _reported_ incidents. They also talk about how some of the cases going unreported. It would make sense to sieve through the radar data (I'd guess all the ATC radars are being recorded, because why not?) to look for those.
- tailspin2019 5y agoYep that's fair enough. And satellite imagery too I guess.
- nradov 5y agoMost ATC now uses secondary radars. Those generally only pick up aircraft carrying transponders.
- trasz 5y agoGood point. What about the radars used by Air Force to guard the airspace? Do they cover the interior, or only the borders?
- xxpor 5y agoSecondary radar == just an RX only antenna?
- nradov 5y agoTransmitter also, but not powerful enough to get a useful return from an aircraft without a transponder at any significant range.
