Some of you think that people are just glued to radarscopes watching the paint of every aircraft don't you. Just because someone wasn't watching it at the time doesn't mean surveillance data doesn't exist.
Most modern and even semi-modern ATS systems are able to store substantial amounts of surveillance (ADS/SSR/PSR) data and replay. In addition, raw feeds from the radar (PSR/SSR) are usually "processed" to improve accuracy and reliability and may actually show more than a controller could see.
And to those who said "one primary paint is all you'd need to know where the plane is" you obviously have never actually been inside any kind of area control room or watched the screen long enough.
Subject to surveillance coverage, there will be much more data available than on one of those joke websites run by rampant aerosexuals in their pyjamas.
