Was the destruction of the twin towers scientifically possible on 9/11

Imo there would be no logical reason for the Islamic conspirators and the organization behind their incredible victory against the alleged infidel, great satan to give credit for their masterful feat of destroying the world's two tallest buildings to US demolitionists, their only weapons being a few bucks worth of cardboard box cutters.

Well, DA, The knifer killers were Islamic fundies. Right? Likely if explosives were set throughout the building they would have been Arab looking Islamists and very likely have gotten detected. I believe the implication of the conspiracy theory is that other than Islamic fundies allegedly did all the sophisticated detonation setup throughout the building and the conspiracy people want to shift the blame from Islamic terrorism to other, such as the Israeli or US government and that Islamists would support the conspiracy claim so as to debunk the justification of invading Afganistan and Iraq.
My message was to the effect that the Al-Quaeda would want credit for this masterful victory by a few knife wielding terrorists.Also, likely the actual implementers of the plan would not be co-conspiring with anyone but other Al-Quaeda people to do the job.Does that clarify my point?
