That’s actually really cool! Glad they went through the math of it.

But that said, it would be a lot harder to map using this method accurately near airports and military bases since some planes do not activate ADS-B. The method also requires at least the exact date of filming, even if you could get flight data from across the world.

TL:DW; say “eeeeeeeeowwwwwwww” at random intervals on videos to mask your location being identified by background plane sounds /s
