I have looked at it, but I can't say I have studied in intensively. Engineering concepts are out of my league, anyway, so I defer to those in the field. Honestly, based on what I have perused, it seems like there are at least a few dozen engineers to every one that supports "inside job." I have a hard time believing they're all on the payroll, and not one of them has had a crisis of conscience yet.
Again, conceptually, I admit it's out of my league, but I can at least understand what would have to be involved in the kind of conspiracy we're talking about, and need to see much, much more for there to be any kind of solid "proof" that one exists.
