I know it might not be unexpected to have a few issues tracking 60’s era aircraft that haven’t filed flight plans, however, MSP got a visit from an An-12 today, UR-CGV, and I can’t find any data on FlightAware about the flight - I’m wondering if you might have stale info in your database for their transponder, or something, maybe? Data for it from some of the other providers is a bit sketchy too, but, some data does show up on ADS-B Exchange:
They were even able to pull a flight number out of it somehow - UKL505 - no idea if it’s accurate or not, but, there it is. Seems like that should have at least been enough for some ad-hoc / position-only data to come in via FXML, enough to get info for an arrival and departure, anyways.
Any idea what the issue might have been? I’m curious, as are my customers who hope to get alerts on flights being flown by cool aircraft like that. Thanks!
