Does the damage pattern to the No 1 & 2 engine pods not suggest the engines hit the ground during the latter stage of the reversers being stowed? (ie mid way down the pod, as the reverser cowl has been dragged forward, it has hit the ground).
Doesn't really look like a high speed overrun either does it? Will be interesting to find out how close it was to being a close shave rather than a very expensive day at the office
