In one sentence you state how you wish you could hear from someone qualified in demolition to give you the scientific explanation because unless you are an engineer or demolition expert don't bother as too complex
And in another sentence you suggest we could all agree there is only one way for a building to collapse this way
So which one is it - do we need to be qualified and experienced engineers or demolition experts to make a judgement about how the building collapsed or can any layman make a judgement as it so obvious. Possibly with the help of a 30 minute youTube video which of course is the rough equivalent of a 4-5 year engineering degree and double that in experience on the job.
And two points to consider
1. Having a fire in a skyscraper created by and electrical fault or a stray cigarette in a rubbish bin may be a completely different scenario to one started by a 200 tonne jet loaded with jet-fuel crashing into the structure at 500 kms/hour. Don't you think?
2. WT7 was hit by massive chunks of concrete and steel from a falling skyscraper, had fires break out with no water to fight them and the main area of damage was supporting 40 stories of weight in a now completely unstable manner. Think there's a chance these factors might have destabilized the structure somewhat?
