The question that needs to be asked, with any scientific theory, is can the experiment, in this case steel structures, be "dustified" with dew or lasers or soundwaves. If not, or experiments not tried, that is thin evidence. I don't follow any one theory over another. I believe "Knowing the means" is an ego trip to anyone that has investigated. What is conclusive is this was an inside job, and it was controlled demolition.
