Flight History
Sometimes you want to find out where that plane has been, or what it routinely does.
One way is to click the ADSB Other Tracking Info pulldown then Flight History.
You can search on ICAO number,
Registration, or Callsign.
Some of these searches don't work or hang forever.
If it works, you'll get a list of flight history that's available on ADSBexchange, by date.
Try clicking a date to see the whole flight trace on a map.
These can be quite enlightening.
We'll get into other websites, several ways to track civilian aircraft, other ways to get flight history, etc. later, as needed.
