I am new to this and find it interesting. I was looking at flight tracks detected by my PiAware. When I clicked on a particular airplane icon it showed the flight was available in FlightAware. When I clicked on the FlightAware link in PiAwaredto see the flight track in FlightAware, the flight in FlightAware is no where near the flight picked up by PiAware. For instance, I am near RMN (Stafford VA) and a flight was traversing SW to NE. When FlightAware displayed what it thought was this flight, it displayed a flight between two airports in TX. I found may of these. I should mention that none of them were airlines. They were all N-numbers for GA airplanes, so far. One was a Bellanca Viking. PiAware showed it at 16,000 feet. I know a Bellanca would not be flying at that altitude.
