Air Loom - 3D Flight Tracker
Pretty neat visualisation of aircraft flight paths, all in 3D. Little bit bare but also fun; I can imagine it getting more comprehensive over time.
A favourite episode of QED from my teens, where a RAF Hawk flew round the coast of mainland Britain. The show itself is about 1/2 hour long, and concentrates very much on the changing geology. The flight itself is sped up about 10x, making it a mach 10 flight, give or take.
Very BBC. Very 80s. Very cool for the time.
