Trawling through the web while Angel does the ironing (it’s a hard life) and I stumbled upon a fantastic animation done using FAA flight information here.
Watch the animations, they are well worth it! (click "Read more" to see the embedded video)
Ok, I confess, I went to see the Spice Girls at the O2 Arena last night. It wasn't my fault, the man with the free VIP lounge with free hospitality (inc. bar!) made me do it! It was an impressive sight, but I certainly wasn't there for the music!
P.S. I will try and get Angel to write more about the experience.
