>It also states that 30 seconds elapsed between touchdown and crash.
This would fit with the video footage. the straight line distance between runway 35L treshold and the crash site is 2km (from GoogleEarth). 30 seconds would mean an average speed of 240km/h, equal to 130kts. Approach speed for A320 (62t, 2500ft, conf full) is about 130 to 135 knots.
The 30 seconds are surely no exact time (+/- 5), as is the distance (+/- 200), but it looks like the aircraft was rather fast (for a landing).
