I did find a plane tracker before but cant seem to remember the name its similar to RadarVirtual, I seem to remember it was called Pathfinder or something similar.
There`s one called flightaware too. It`s American I think as it tends to show what`s going on over the Atlantic. I like radarvirtuel too.
I keep meaning to find out where they all get their data from but keep forgetting to ask. If something is completely off-schedule it`s not always on there. My sister took off for JoBurg at 2am and there was absolutely no sign of her aircraft on any site. Strange.
