Hello,
C-SAR, thank you, it would be very nice if you could look at the initial impact zone, and if those "white" traces are related or not to impact, and check roughly the width of the initial trail. If you can walk the zone, looking at what are the first debris would be helpful.
I think also that it is not wheels contact that left this track, seems too tiny.
Contact could be made nose up with full power applied for a go around; tail hit first and trailed on the ground. Mosque road caused a bump further weakening the airframe and caused tail separation which rotated, then cabin came down after the mosque and starting to desintegrate along the trail. From initial contact to where wings are lying, the distance is between 800-900 meters. Part of the landing gear is lying near the last road just before the airport's limit.
I don't think that "Alitalia rumor" is very relevant. Beside, thank you for posting this Dutch link as the full trail travelling is very interesting.
