> spoofed locations that are physically impossible to receive by said receiver? Wait until you hear about Sporadic-E or Aurora. RF is a weird place full of natural phenomena making the impossible very possible.

But even if that was the case, is there any value for a receiver to be receiving those? Surely those messages would be picked up by a receiver closer to the transmitter anyway. I think the value in spoofing rejection is greater than the probability of a transmission reflecting from beyond the horizon and not being already being picked up by a local receiver.

Yes, radio propagation is an entire academic field to be studied :)

In addition, if you have enough receivers you can use that to run something called MLAT [1] to also pick up GA aircraft that just have a transponder but no GPS. The more the merrier.

Domestic terrorism is now an official policy goal of the "US" government, so yes, there is a lot of it.

Easy to justify the murder of your political opponents by calling them domestic terrorists. What's almost more frightening is how many people actually buy it.

I'm still chewing on the idea of how many supporters are bots or at least bot-adjacent (ie manufactured social proof), and what can even be done about that. When I go to my local [small, suburban] protest in a balanced red-blue area, lately it's been many honks and agreements, and only a handful of angry grimaces.

So I think the tide has long ago shifted, which makes sense what with the terror gangs executing Americans and all. The question is how we can organize into meaningful opposition when most activity happens online these days, and every non-echo-chamber forum still has extremist nutjobs who derail productive conversation.

I'd think that Congressional offices are seeing a similar dynamic too, inundated with robocalls from "constituents", the occasional untraceable threat of violence to their families if they step out of line, etc.

airplanes.live, adsb.lol, ADS-B Exchange, adsb.fi, etc. do not censor the data.

It's happening again. Spoofing is in progress, rendering another image. ADS-B Exchange has blocked access to the ICAOs/hexes in question--if you try to look at their history you get redirected to the base map.

It’s not “illegal broadcast which engages the FAA and FCC to hunt you down” illegal, but that doesn’t exclude other prosecutions.

Other persecutions for what? Sending crap data to an API is not a crime.

It's literally "computer fraud and abuse" in every sense of the word, so one assumes that an avenue of potential prosecution and possible conviction would be under the CFAA act. This does not, of course, guarantee that a conviction would be made and upheld at appeal, but this community is quite familiar with the dire harm that federal prosecution for misuse of computer services can impose on individuals, no matter how misguided that prosecution may be. Prosecution can be wielded as a form of persecution that does not require a conviction as outcome to be successful, and that is the a pressing risk now faced by whoever did this.

Less than 100$. That's what many people, both aviation enthusiasts and ham radio operators, do for fun. The problem is, do that on an airport?

All good points. I'd set it up very near the airport but not on it and then access it using the same web browser that I'd use to go to ADSB Exchange.

Why? You would almost certainly get better data with higher reliability and no effort and no money spent from airplanes.live, adsbexchange.com, etc.

The problem is, you need to have a good height for the antenna - "height is might" in radio, particularly above VHF bands. I actually can see this with my own ADS-B receiver - I'm in a valley and precisely can see that effect when plotting received packets.

I get good distance from my ground level antenna, but while I'm in a valley, it's very wide and long. My assumption is that most airports are going to be in fairly flat areas.
