I imagine the pilot overshot the runway as the weather was bad so unsure if it was icy.
I'm amazed the car driver didn't utter a word, scream of anything, and calmly pulled over, probably as it happend so fast. Must have been hell of an impact as you can see what looks like a row of seats lands on the motorway and the car runs over the top of them
For some reason you have to watch it on a PC. It shows 204 landing about half way down the runway on an earlier flight. Crew didn't seem too concerned about getting it on the ground.
