Of course Flight Radar has it's (limited) uses. But consistent with the drivel that now populates this site whenever there is an accident or incident you will get people who ascribe to FR something it isn't - a comprehensive and accurate tracking of all commercial aircraft movements. It's great when you gave to travel an hour to collect someone on a long haul flight as you can time your arrival appropriately. But those ignorant enough to to use it for much more than that only give away their own limitations to critically analyse information.
