Jet Tracker Sites: any chance we we'd know of a "Big Event" when there's suspicious flight activity?
Like if all the swamp lizards are flying their jets to Antarctica or some shit
know of a site that tracks this kind of thing?
Exactly.
And you don't need any site to track planes over your home. Even cheap RTL-SDR dongle and simple 1090MHz antenna will give you info about all planes within up to 80 miles radius for planes on 30kft altitude. At least for ones that does not turn their ADS-B off.
