Frangible, Gianmarko. In skid or not, the triangle made for the contact point of the nose gear and the each center of left and right parts of the main is a
very well definted triangle; isn't it?. So you could perfectly place the nose gear (supposing no elevation) if you had the right scale, at every situation of the main gear. What can be done for the moment is a quite inexact estimation, but in my opinion quite enough to make clear
a very different path.
The composition I made is very far from being accurate, but I think it gets quite clear

CaptainPlyStation. I'm not trying to conclude a complete identification of the marks from here. But if you are suggesting that concluding the centre marks cannot be the nose gear could need several months from an Official Investigation then you are not giving much hope worth waiting for the real explanation of the accident
