Other week in California, I had a UH-60 Blackhawk fly overhead fairly low over my home.
Ran outside to check, and to my amazement it didn't come up as such on globe.adsbexchange.com. The helicopter was showing as a civilian single-engine aircraft, believe it was a Piper or Beechcraft.
That should say something when you see a lot of 'trainers' in certain areas. You never know what they could be now.
We have the technology to make you see whatever they want you to see. A lot of people put emphasis in tracking flights for the most part it will show us activity but anything important you aren’t seeing what or who it actually is. It’s like a switch they have.
Think about it if average civilians can read the flights. Dangerous countries can as well and that would be the worst case scenario if something were to go down. They could take out everyone important.
the trick to reading the skies isnt to track a flight. you track the patterns and find the oddities. like crafts making repeated low dives over the ocean generally signifies a carrier.
