But blowing a single column in the interior of an empty building may not be very loud, especially in the chaos of that day.
Again, if buildings can be brought down with the loss of a single column, maybe AQ, smart enough to catch the entire military/intel community with their pants down, also knew the fatal flaw in WTC 7.
Hi Red. Just a quick comment about your last statement. But first, I noticed that you were attacked as soon as you showed up on the thread, so I don't necessarily blame you for being defensive.
You are engaging in wishful thinking when you say 'blowing a single column in the interior of an empty building may not be very loud..'. The problem is, you're just pulling that idea from nowhere; it has no basis is fact, but is speculation. I assume you wouldn't be able to point to any scientific study, or demolition footage, or demolition experts to back you up.
In contrast, NIST actually used several different methods to examine the explosives claim; you have been informed about this already, I'm sure. This included consultation with actual demolition experts, who did analysis; the use of standard industry software, etc..
In other words, competent engineering opinions.
You're not offering proof, you're just looking for excuses not to accept legitimate inquiry and investigation that has been completed and published.
You also use the further excuse that the chaos of the day may have distracted? people, but you fail to acknowledge the audio recordings, which were not distracted, and didn't pick up any noticeable explosions at the time of collapse (when the main column in question failed).
If you continue to ignore solid engineering, you will probably continue to come up with the wrong answer to the questions. It's your choice if you want to do this, but don't expect accolades from thinking people!
cheers
