I have not yet noticed any witness from those undoubtedly numerous who were driving along the N200, who could say how low the plane was when it crossed the road. Tomorrow we will without doubt be wiser on this issue.
Sensible remark,
Yes witness reports of motorists on the 6-lane motorway (about 500 yards from the impact site) have been gathered and passed onto the Dutch "AAIB". Even commercial pilots saw it happen in the traffic jam.
Unfortunately (I guess) gathered in a non-english language..
...and at a suitable reporting date (if it was only for xxxxx-xxx-xxxxxx) very likely in English.
