There's a few out there but it's not certified. The only ones in the field are experimental exhibition registered. Not sure if things are progressing at all now that Textron bought them.
Landing at the flea market, where the helicopter has been pretty consistently in service for years. Pretty much right next to where it happened, and just west of DAB. He definitely wasn't doing anything he shouldn't have been
The FAA publishes a list of callsigns.. Odds are good that Kilo Charlie just has a "local" approval for Pit-Boss. They weren't using that when I was at IXD, so I assume it's new-ish. Outside of Kansas City area, I assume they go back to their tailnumber.
Totally derailing the thread here -- is the museum even open ever anymore? Last time I was there was SnF in ~2019. Haven't been (or tried) back since relocating to FL.
But not exclusively, like ADSBExchange. Flightaware also receives and displays a tremendous amount of data from the FAA (and other government sources around the world). That's why Flightaware hides flights (required by the FAA) and ADSBExchange doesn't.
Ah somehow I totally missed that you were doing this yourself. That's a very significant amount of work, and without some experience/guidance it seems like it could literally take 5+ years.
Best of luck, this definitely isn't for me faint of heart.
