Forgive me for being thick but what b*y picture are you talking about?

I can't seem to find anything in the BEA report that has two men standing on tyre marks.

Yes.
Fig 73 looks at the effect of malalignment of a bogie with the aircraft following a straight line path. Note how the RH gear is still lined up with the aircraft track.

By the time any evidence of oscillation is observed the aircraft was 9 seconds into a 10 second rotation, so I can't see how it could have had any effect on the earliness of the rotation. There is,...

Lyman

You can find Nx in either in Section 1.16.13.2 of the BEA report or, more exactly, in Fig 1 of Annexe 4p of that report.

Hi Chris,

That was indeed so, but #4 was spooled up with the others at 60 kts and the left rudder input from the FDR trace was at 100 kts - no obvious reason for it either.

As you requested, I looked at that picture very carefully, and yes, there is evidence of a shimmy-like oscillation in that part of the track. However, I also looked at the other pictures...
