I love the Internet. It's like having the whole world of knowledge at your fingertips. Been told something you consider a little far fetched? Google it and sift through the answers. All you have to be is a little sceptical and discerning.
Am currently tracking Wife's flight using this handy little tool. It tells me when the flight took off, when it's due to land, and there's even one of those handy dandy little graphics with a cute little aeroplane showing you the flights approximate position.
Brilliant. It takes all the worry out of the process. This particular tracker does transatlantic flights, unlike others that only track in US and / or Canadian Airspace.
