Bomb Damage Analysis Of Alfred P. Murrah Federal Building
Oklahoma City, Oklahoma
PART FOUR
Seismograph Readings
Much has been said about seismograph readings. Was there more than one explosion? Most people I talked to in Oklahoma City heard two explosions
relatively close together. Some close by said they didn't even hear an explosion. That is not unreasonable, when you consider that getting walloped by
an intense shock wave is about like being hit across the ear by a 2" x 4". One would expect the demolition charges to have had an electrical or
primacord interconnect. If so, it would be difficult to separate them on a seismograph. If delays were used, they would be discrete. If a sensitivity
switch was used inside the building, the explosions would have been distinct. Bomb initiations could have been easily designed to go off either
simultaneously or with separation.
Conclusion
The Murrah Federal Building was not destroyed by one sole truck bomb. The major factor in its destruction appears to have been detonation of
explosives carefully placed at four critical junctures on supporting columns within the building.
The only possible reinforced concrete structural failure solely attributable to the truck bomb was the stripping out of the ceilings of the first and
second floors in the "pit" area behind columns B4 and By. Even this may have been caused by a demolition charge at column B3.
It is truly unfortunate that a separate and independent bomb damage assessment was not made during the cleanup__before the building was demolished on
May 23 and hundreds of truck loads of debris were hauled away, smashed down, and covered with dirt behind a security fence.
When the picture at Tab 4 was made, all evidence of demolition charges had been removed from the building site (i.e., the stubs of columns B3, A3, A5,
A7 and the demolished junctures at the header with columns A3, A5 and A7.
All ambiguity with respect to the use of supplementing demolition charges and the type of truck used could be quickly resolved in the FBI were
required to release the surveillance camera coverage of this terribly tragic event.
Air force general Ben Parton is an expert on muitions to say the least...he as two deegrees and phd....
those are his words.....
I have no doubts he is right.....
The goverments of the whole world engage in this *snip*!
