used, well what about what the firefighters and news reporters who stated they heard loud booms just before and during collapse? Just looking for your
thoughts as I am somewhat new to all of this.
Well the firefighter accounts are difficult to know what they're referring to. There are definitely firefighters who mention explosions, but these
refer to events even including bodies of jumpers hitting the ground.
I'm more taking issue with assigning the 'perimeter panels were ejected' to explosives. We can easily do some calculations here, a 4000kg panel at
20m/s (reasonable values) has energy E=0.5mv² so E=2000*20² or E=2000*400, so we know it has E=800KJ of kinetic energy.
Now, lets assume a perfect explosion where it puts a full 50% of its energy into accelerating a panel. We know that the explosive release must have
been 1.6MJ in that case.This is per perimeter wall section
If we then assume there were only say 20 of these explosives on a level, then we know we have to detonate about 32MJ worth of explosives at the
extreme minimum. This is almost 10kg of TNT equivalent per level
. NIST did the calculations for this in the WTC7 report and with less explosive
than we're talking here a single detonation should have been as loud as a gunshot up to 1km away. The videos of the collapse don't have anything
remotely like this on, and we also don't see any high speed shockwaves or other indicators of detonation.
It doesn't make any sense at all. Why would someone go to all of this trouble to hide a demolition, but then use extremely loud and obvious
explosives. If they were going to take the building down there are much saner attack methods. This is in extension to my above post as it seems common
for people to assign suspicion to every
element and then use that suspicion to doubt any explanations.
I hope we can come to a good agreement on what any shadowy conspirators would want to achieve, I don't think they had any need to put such huge
explosives in place (nor any practical way to do it!)
