Reply #114: I think you will find that my posts are not irrelevant. Please review my past postings if you care.

I am a degreed mechanical engineer with over 30 years of experience. I am happy to provide my credentials to anyone who thinks I am a liar. I am not a PE or structural engineer, but I did take and ace every ME course that WPI had to offer through the graduate level. I analyzed thousands of trusses back in the day, even though my current line of work mostly involves sub-micron mechanical vibratiions and resonances.

In some of my early posts on DU I provided the calculations showing how much energy was transferred from the 767 impacts into the towers. If I recall correctly, it was 2.83 GJoules, which is a significant percentage of the Hiroshima bomb, and also roughly equivalent to the Murrah Federal Building truck bomb.

It is my informed opinion that the structural damage caused by the airplane impacts, coupled with fire, was the only cause of WTC1 & 2 collapsing. I am still trying to absorb the Bldg 7 report.

I will add that I believe that the information to disrupt the attacks was available, at least piecemeal, to various elements of the US intelligence apparatus, but for reasons unclear to me, the information was not used to prevent the attacks. How high up this negligence goes is not known to me.

I reject all theories of CD, nukes, energy weapons, no-planes, etc.

Reports of thermite nano-spheres may make good reading, but because something may be possible does not mean that it happened. I require a higher standard of proof - like what a court of law would require.
