you start to suspect that they're done for a purpose.

Especially in the case of building 7, where it took them 6 years to cobble together their explanation.

Deformation of the girder flange may not be cited in the NIST report, but the idea that it was possible makes their walk-off explanation more plausible than it would be if the stiffener plates weren't there.

I'm relying on memory here, and I never was an expert on this issue, but I believe that independent calculations of the thermal expansion show that the girder will not be pushed all the way off its seat.
