[blockquote]Estimated speed abeam the camera : 100 kt[/blockquote]
To those who would suggest that the movement of the camera would exaggerate the speed, or that the perspective of the runway (going from abeam to moving away) would make it appear to be slowing down, here's how that figure is arrived at: in the 4 seconds it's on camera, the aircraft travels 5 plane lengths. Length of an A320 is 37 meters and change, so back-of-the-envelope gives 170 kph, or approximately 100 kt.
