Sure. When analysing any complex problem I automatically start from the potential global scope of the outcomes. And that, for WTC 9/11, includes the possibilities of human assistance in the collapses. Just because you "already know the answers" is not legitimate grounds for eliminating some possibilities from the outset when you are constructing a logical argument or explanation. Nor, by my standards, when we already know that human assistance must be in the potential mix can we pretend "green field" that we do not know the existence of that option.
You will see where that stance places me relative to several types of players on this forum.
Whilst being an old fart has something to do with it my approach probably the result on many years in conflict resolution roles - mainly Customer v Organisation and Worker/Union V Management plus managing a variety of staff v organisation issues.
I tend to see the range of alternates and where the other players are coming from quite quickly - then need patience to wait till some or all of them catch up. Lack of patience the failure point on some occasions.
