If full thrust was applied at impact, could the 'give' in the mud on the ground be enough to cushion the engines and avoid tip contact with the fan case? The fan blades look pretty much intact which doesn't square with what happens in a conventional high rotational speed engine impact.
The mud will not cushion the impact.
The one engine has crushed against the fan blades that's why they are not in perfect alignment with one another.
However the timing of the impact to the fan is critical when one considers that if the tail struck firstly then the fan rotor may have been stopped or slowed down by crushing of its drive turbine.
With only a couple of pictures we can't tell but the on-scene folks already know.
We have to face the fact that we don't have facts yet
