Well, right next to the icon it said "CLX778" and when i clicked on the icon, it said what the altitude and speed was. Why, are you saying that it may not have been what it was tagged as?
This was earlier today, round noon-ish CST. I followed that one all day - it dropped off the screen for a brief time after it entered the Atlantic track but then picked back up again east of Iceland and all the way to runway 27L at O'hare. but I first saw it just off the coast of Belgium.
So let me get this straight - Google Earth are now doing flight tracking, including the UK?
I have Google Earth already installed. Please provide the link that makes these flights show up with tracking tags.
