I would like to fetch a few high level values from the aircraft.json from dump1090-fa/data/aircraft.json.
Getting the data and going through the values is not the problem. What is confusing me is that I have roughly 30% more records in “aircraft” than what the webpage under dump1090-fa is showing as “Total Aircraft”.
While the webpage tells me there are some 28 aircraft (including the list in the table below), I do get some 38 aircraft records in the .json. I have gone through the data and also looked at all the various fields in this description of the data: https://gitlab.rhrk.uni-kl.de/s_schumb/dump1090/blob/master/README-json.md
But I can’t find the criteria as to when dump1090-fa is “counting” a record and when not. Is there a simple rule to that?
