RbF,
Just looked at Hobie's posting of the side view of an MK 747 departing and from that it would seem the gear all retracts at once, not "outboard first, then inboard". And that the outboard gear aligns its "dangle" close to the well rather than prior to the folding-inward motion. So the thought I threw out earlier re an attempt at gear retraction is probably off base.
The only other thought that occurs is that the outboard gear is designed to compress more easily; it's the first to touch the ground on landing and the last to leave the runway. Could it be that the outboard gear actually did ride up the berm but, more easily compressed, without leaving marks discernible in that low-resolution photo?
If the outboard gear didn't touch the berm at all it's back to AoA.
