The straight track surely cannot be the NOSE GEAR. Given the obvious MAIN GEAR track, it is purely geometry to know where the nose was at every moment, and it's path would also a curve; it can be easily deduced it cannot be the straight track of the image. (And never mind the possible drifting, of course).
If I knew how to attach an image I would post a somewhat approximate drawing
For me it's quite sure that the nose was up at that moment
