How refreshing to see this! A thoughtful response to something I wrote.
I can't speak for other engineers. Just because someone is an engineer does not make them correct (Myself included). To be honest, I have not heard any arguments supporting the controlled demolition theory that were made using structural engineering principles. Whether or not they are put forth by engineers or not is of little importance to me.
The arguments all seem to rest on insubstantial evidence like: a steel building has never collapsed from fire, fire doesn't melt steel, a news reporter reported that it collapsed before it did, it fell too fast, some guy heard explosions. None of this is substantial evidence.
I would entertain arguments from fellow structural engineers. I would love to hear arguments based on sound structural engineering principles. I just haven't heard any yet.
