I searched, but did not see anythingthing previoulsy posted about this website I just found.
Check it out! Real-time flight tracking over Amsterdam. VERY COOL! You can get a pile of information from it. It seems legit, having done a few cross checks.
Make sure you zoom out, and use the controls on the left of the screen.
The info comes from SBS reports passed automatically by the aircraft to whichever ground station. All that information you are seeing on that map comes from an SBS Radar-box program, a laptop, and a small antenna on the roof of a building at AMS. It tells you all that info on the site if you look, as that’s where I got it from some time ago when I looked.
Oh and the info is NOT real-time. It’s delayed by around 10 mins iirc.
