I still have no idea why the nose-wheel was not centered. From the start of the take-off until the complete stop was about 600 meter or so.
Tower warned the cockpit crew about the heavy smoke and within 10 seconds the emergency crew turned out (they must have been sitting in their trucks, amazingly fast).
The fire dept. monitored the nose gear for a while but no close up check by an engineer was conducted.
After 15 minutes the pilot did give a short explanation to the tower about 'some system not set right and they had fixed it' and 'he felt confident about the situation to give it another attempt' but it was difficult to understand. The tower gave the pilot the option for a push back to the start of the runway.
The pilot asked to take the nearest exit to get back in line with waiting traffic (already 6 planes waiting) but the tower, probably worried about the very sharp exit turn it had to take, asked if 2300 meters of runway was enough, and after some calculations were made, it was.
After the successful take-off the runway was visually inspected by airport authorities for remaining debris and operations continued.
Besides the full left rudder, also note engine #4, it seems not operative. With a shutterspeed of 1/400, f/2.8 it expect it to have blurred like the other fanblades did.
My gear: Nikon, Sony, Red, Sachtler etc.
