FlightRadar24
I did follow quite some discussions in the past and actual on pprune. I am amazed of the view of some on Flightradar24 data. This is a volunteers (most probably, or told to us, or make us believe) network of unknown quality, mostly unknown operators with respect to many topics, publishing unverified data on the unvalidated internet. In the end it is a long chain of unknown people, unknown attitude, unknown aims, unknown manipulations, unknown quality at all. Estimating from stories told to us, it would not be difficult to feed any fake data you want and there is no way we are able to judge the validity of data as an individual (you remember the term?), but somehow so many believe. Do you pray to FR24 already?
