The Partin report is at the core of the additional explosives conspiracy theories but his assumptions have a fatal flaw easily exposed by some very basic math. I’ll refer to one of the many copies of Parin’s report available on the internet;

“The maximum possible yield from 4800 pounds of ammonium nitrate would be obtained if it were in a compressed sphere and detonated from the center. That would produce a 4.4 foot diameter sphere of detonation products at about 500,000 pounds per square inch. By the time the blast wave hits the closest column, the pressure would have fallen off to about 375 pounds per square inch. That would be far below the 3500 pound compressive yield strength of the concrete. Any column or beam failure from the truck bomb would therefore have been from blast wave structural loading and not from any wave of deformation in the concrete.”

The crux of Partin’s argument is that an overpressure of 375 PSI on the closest column (G20) could not have failed it because 375 PSI is less than the concrete’s compressive strength of 3500 PSI. The column would not fail in compression though - it would fail from tremendous side loads. Failure in compression would be like putting a one inch square of concrete in a hydraulic press, 3500PSI concrete would require 3500 PSI of pressure to fail in compression. But construct a column of concrete one inch square and say ten feet long. Support the ends and load the middle, will it take 3500 PSI to fail it in bending? Of course not. This illustrates the difference of failure in compression and failure because of side load. Column G20 was 36” x 20” and over 20 feet tall. Lets talk about the 20” side being exposed to 375 PSI overpressure. At 375 PSI overpressure each foot of column G20 would have a side loading of 90,000 pounds. This means a ten foot section of column G20 would have a side load of 900,000 pounds. That is an instant side loading of 450 tons on a ten foot section of column G20, now consider the column is over 20 feet long. Do you think it would collapse from this kind of side loading? What totally destroys Partin’s analysis is using a 1457 PSI overpressure on column G20, something one of his own illustrations shows. This means the side loading on the same ten foot section of column G20 would be 3,540,000 pounds or 1770 tons of instant side loading.

There are other oversights in Partin’s analysis like the fact the Murrah bomb was ANNM (ammonium nitrate / nitromathane) not ANFO (ammonium nitrate / fuel oil) plus it was shaped. Shaping the charge can radically change the blast effect because of converging shockwaves (Munroe effect).

For more reasonable and logical analysis of the Murrah building failure mode see this link;

“The attached report contains conclusive proof that the bombing of the Alfred P. Murrah Federal Building, Oklahoma City, Oklahoma, was not caused solely by the truck bomb. Evidence shows that the massive destruction was primarily the result of four demolition charges placed at critical structural points at the third floor level. “

If that's all you think it involved then I'll be taking you off the suspect list.

Chuckle, you can take me off the list.

I could have done it I guess, we used fertilizer as the explosive for a 'remodeling' project that involved removing large concrete walls inside a livestock building. No diesel fuel though. Back then it was simply a cost issue, we cut the dynamite way back and replaced it with fertilizer.

I am aware that there was a lot of 'planning' that went into OKC, but the explosive part itself, nothing to it. Even this old hog farmer could have done it.

I've never understood all the 'planning' though, if I were doing it I sure wouldn't want to expose the whole project to that risk .

I think it's more about getting the final courage.

Interesting report:

A very close friend of mine was at the time
an Asst. Fire Chief in the Denver Fire Department.

He spent a week in Oklahoma City as a first responder.

I have a background in shaped High Explosives
and blast patterns from the military.

I asked about a the blast crater.

He assured me that there was no blast crater.

There was no damage to the building across the street.

So I find your report suspect.

AND I worked at a large hospital in OKC where numerous middle easterners were brought over for workup for liver transplants.

Yeah, just taking the livers that Americans won't use, sure.....

I have only one question....does anyone have a picture of the blast crater?

>>the direct result of the governments aggression

OKC was the directly result of methamphetamine fueled stupidity.

All it ultimately accomplished were dead pre-schoolers, a new and improved Federal Building in OKC, and an even more out of control government Bureaucracy that used said stupidity as justification for inching further toward the police state that human governance, by human nature, ALWAYS tends toward.

OTOH, When Gandhi made salt....

It's not *my* report. And it is a lot more objective than a lot of what you see out there. I've seen pictures of the blast crater. It was partially filled with debris from the building's progressive collapse [1] [2] . There was a lot of damage to surrounding buildings including glass blown out up to 10-12 blocks away. There were 17 closer buildings with structural damage.

Please forgive me if i infered this was your report. That was not my intention. It is just that in all of this, there has NEVER been a published picture showing a blast crater. As a matter of fact, the only picture i have ever seen clearly showed no blast crater, with rescue crews standing where it should have been. That picture has since disappeared.....

I was indoors in bed after a surgery, about 8 miles away (in Moore) It rattled my windows.

That’s interesting, I was in the hospital recovering from surgery when 9/11 happened. It is hard for me to imagine a time that I felt more helpless.

My wife’s cousin was on the 104th floor of the north tower. She was coming to visit me when the tower fell. Under medication, hurting from the surgery, and overwhelmed by the events, I was not much comfort to her.

Were you stationed at Tinker AFB in ‘95? I was on the base on 9/11 and felt very vulnerable, as I feared we might also be a target. Is your wife okay? I imagine you both experienced PTSD from that day, God bless y’all, stay safe.

“Were you stationed at Tinker AFB in ‘95?”

Yes, moved from OK shortly after the May 3 ‘99 Tornado. Sheesh - I'm a catastrophe magnet. ;)

We're fine. Thanks for your concern. Wounds heal, but we won't forget.

“I’m a catastrophe magnet.” ME TOO!!

This is uncanny. My husband and I, with God and our pets, were hiding in a closet during May 3, 99 tornado. (Kids were out of town at the time) Our house was demolished, he got a 1/2 inch scrape on his leg, I got a dime-sized bruise on my arm...the other good news is that we had full-replacement insurance, moved out of Moore and now live on beautiful 5 acres in the country. My 14 year old cat still has trauma during storms, though. The love shown by others at the time was the best thing to come from it.

Andreas Carl Strassmeier. Carol Howe. John Doe Number 2.

And the pre-blast Fed flurry and the guilty pre-knowledge of some who awaited a different outcome.

The FBI and ATF may not always be right, but they are never wrong.

And Ramzi Yousef and Terry Nichols--"he was just a guy in my neighborhood who did something when I was eight years old"--

There was an Indy Star writer who also risked all to investigate.

Case not closed.

...three middle-eastern looking men...

...six swarthy men of Middle Eastern extraction...

Should we split the difference?

You too have been through a lot.

“The love shown by others at the time was the best thing to come from it.”

I wish, REALLY wish, the “Oklahoma Standard” was the way our Nation responded to disasters. After OKC bombing and the tornados, Okies just picked themselves up, dusted themselves off and then looked for someone to help. I don’t remember anyone whining for government help. Churches set up shelters and served food. People used pick-up trucks as ambulances and offered their homes to those who lost theirs. I don’t remember ANY looting.

Compare that to Katrina.

UriÂ’el-2012 said “your report”. Anyway I just looked at two pictures of the crater again, it is pretty full of debris from the building collapse and covered with a tarp. The FBI didn’t excavate the crater until day 11 or so, it was filled right back up within a day so other work could continue. Here’s a document that has the entire timeline;

The hand wringers were the East coast and West coast papers wondering how those red neck hicks in “flyover country” could cope with something like this!

The handwringers didn’t realize that Oklahoma has had years of tornado disasters and were well prepared even for this!
