Overpressure bombing effects (or why Zarqawi still had a face after the bombing)

http://www.alternatevoice.com/blog_archives/000148.html ^

[Pukin Dog]

One of the least understood phenomena of a bomb blast is overpressure. Everything in the blast perimeter is subject to a sudden and profound increase in air pressure. This wave of blast overpressure declines rapidly the further it travels. A person 10 feet from a bomb blast will experience nine times the overpressure of a person 20 feet away. But it gets messy and unpredictable. A person who happens to be standing between the bomb and a strong wall is subjected to more blast effect because solid surfaces reflect the blast wave.

You, as you read this, are subjected to normal air pressure of 15 pounds per square inch, depending on how close you are to sea level. The rapidly expanding gases of the bomb push the air out of the way generating air pressures of as much as 700 tons per square inch in the immediate area. But even on the outer perimeters of the blast area overpressures can be deadly.

The human body contains two principal air-filled spaces -- the lungs and the nasal cavity and attached sinuses. A human subjected to a bomb blast wave instantly has hundreds and perhaps thousands psi of pressure pushing on these cavities. A mere 15 psi above normal is considered the threshold for possible lung injury, so imagine what happens to those near the epicenter of a bomb blast.

The chest caves in. The lungs inside it are compressed violently in on themselves -- so violently that the entire network of pulmonary vessels connecting them to the heart and the rest of the body are sheared off.

When the instant of blast overpressure passes, the lungs suddenly re-expand, like a crushed rubber ball rebounding in the hand of a strong man. But now they are filled with a huge volume of blood, blood that should be flowing to the heart and other parts of the body.

Blood that would normally return to the heart through the left ventrical has now overwhelmed the lungs. No blood in the left ventrical equals no blood in the heart equals no pulmonary output to the body. Blood pressure -- zero. The body is instantly starved.

Up above, in the skull, at the same instant, the overpressure works in another way. The nasal and sinus cavities implode. That part of the skull called the cribiform plate ruptures, snaps and may be thrust upward into the base of the brain.

I wanted to post this information because in my happy browsing of liberal nutbag websites today, the DUmmies are claiming that its all a hoax about Zarqawi, since he was not blown to bits in the explosion.

I thought it might be instructive to all to have a nice little detailed explaination of the effects of overpressure on the human body, and how these bombs actually do their jobs, while keeping collateral damage to a minimum.

Anyone who watched the video of the bombing should note that while Zarqawi's hideout was destroyed, houses surrounding it were left intact, along with any people they might have contained.

Dang! Kinda ruined his day didn't it?

[Bahbah]

I was actually wondering about why he was still intact in any part of his body, so thanks, and I must say a thoroughly enjoyed reading the gory details.

[tongue-tied]

Gee Pukin, you mean the DUmmies may not have a clue?

Huh. And I thought those guys knew all, since they have all of the smart folks on their site (according to some of thir posts).

[djreece]

Thank you for the info!

[dirtbiker]

Dang! Kinda ruined his day didn't it?

Yeah, kinda sweet, isn't it!

I love the smell of dead jihadist in the morning.....smells like....VICTORY!

[ClaudiusI]

Will chew gum help your lungs pop back out? :)

[AmericanMade1776]

Thank you Pukin Dog.

[ClaudiusI]

er, chewing. (drat!)

[Jaysun]

Very informative. Thanks.

[Rennes Templar]

The DUmmies claim everything since and including 911 is a hoax, so why not this?

[jazusamo]

Thanks for the post, good info.

[Grampa Dave]

Then sometimes their heads look like this:

[RightWingMama]

Thanks for posting this. I was wondering why he was still intact.

[justche]

Gee Pukin, you mean the DUmmies may not have a clue?

DUmmies aren't the only ones without a clue - I had to call a friend who's former special ops to ask how it worked. This article was much more visual in it's explanation though.

[COUNTrecount]

Excellent post.

[coconutt2000]

Liberals go to sleep every night praying they'll wake up in 1999.

[synbad600]

Wow.

How did you know that?

[Chicos_Bail_Bonds]

This is why Daily Kos, DemocraticUnderground, Crooks and Liars, Kerry, Gore, etc....whenever they speak I hope they speak LOUDLY and ROUTINELY.

The more they talk, the more I want them to talk so the rest of the country can hear these nutbags.

[msjhall]

I was wondering too. Thanks for the explanation.

[Pukin Dog]

Yeah, I particularly enjoyed this explanation.

[HitmanLV]

We discussed this briefly on FR earlier, Pukin. Thanks for the detective work. This is interesting!

[Mad_Tom_Rackham]

A fitting ending for the decapitator. It would only have been better if the blast pressure had ripped his head clean off and bounced it off the walls like a racketball.

[Spruce]

The thought of that demon suffering such a horrific death makes my day even brighter. I hear that he was actually still clinging to life when found. I hope the last words he heard before entering hell were "President Bush sends his regards".

[synbad600]

Well, they do have Al Frankenstein, ya know.

[Lonesome in Massachussets]

Just reading this cheers me up. Thanks!

[John Jorsett]

Human beings have an amazing ability to hammer, tamp, shave, twist, and force-fit any sort of facts into supporting their pre-determined world view. DUmmies are particularly adept at this. In years past, they'd have been saucer nuts and grassy-knoll types.

[Aggie Mama]

This makes me all warm and fuzzy.

[tomzz]

You can feel a pressure wave just standing next to somebody firing a highpowered rifle.

[Centurion2000]

Thanks for the bio lesson.

[SE Mom]

Thanks for posting this information, PD!

Al Jazeera claims showing the photos of him dead is a violation of the Geneva Conventions! Now this is a sweet irony..how many times did they SHOW the tapes of beheadings, of dead GI's and on and on...and NOW they claim this?

The general who gave the briefing this morning in Iraq said there were a LOT gorier pics- but they CHOSE only to show the ones where they'd cleaned him up.

[Mad_Tom_Rackham]

...I must say a thoroughly enjoyed reading the gory details.

So did I. I love stories with warm and fuzzy endings. :O)

[NordP]

A face ONLY A MOTHER could love.....blaahhhh!

May he be greeted by 72 virgins...all looking like Helen Thomas of today.

Ah....a sweet sweet day for Goodness vs. Evil."

[Pukin Dog]

Even up close to an high explosives detonation, the insides are usually turned to jelly by the compression wave, milliseconds before the pieces are then sheered apart, then roasted by the heat. 20 feet of distance are the difference between being turned into meatballs or just blasted like Zarqawi was.

For some particular reason, I just love this subject today......

[ArrogantBustard]

Try firing a hot .44 Mag in an indoor range ...

[veronica]

He looks better in that one. To me. :)

[NordP]

Worst Job In the World: "Cleaner" for Zarqawi

[Enterprise]

LOL!

Allah Akbar!
Allah Akbar!
Allah

KABOOOOOOOOOOOOMMMMMMMMM!

[skeeter]

Hooray overpressure.

[Extremely Extreme Extremist]

"FROM WAY DOWNTOWN, BANG!"

[garyhope]

Wow! This sounds almost as bad as being incinerated in a big tall building after it was hit by an airliner filled with jet fuel flown by a group of insane, intolerant Islamofascist fanatics.

And it's almost as bad as being crushed to death by a large collapsing building or being forced to leap to your death from a 90 to 100 floor building by intense flames caused by a jetliner crashing into your office.

Is it as bad as having your head chopped off by a backwards, barbaric, POS Islamofascist pig? Or being stoned to death by your own family because you were forcibly raped by a member of your own family?

[Tijeras_Slim]

5 psi overpressure at the Nevada Proving Ground in the 50's. Don't mess with rapidly moving air.

[Rabid Dog]

This thread is beautiful!

[Grampa Dave]

Good news re the Hamas thug/enforcer/murderere getting Zotted by Israel.

http://news.yahoo.com/s/ap/20060608/ap_on_re_mi_ea/israel_air_strike_4

"GAZA CITY, GAZA Strip - An Israeli airstrike Thursday killed the top Hamas enforcer in the Gaza Strip."

DING-DONG THE PR!CK IS DEAD,THE WICKED PR!CK IS DEAD!!!

[Dinah Lord]

Thanks for posting this, PukinDog.

Poor DUmmies, their widdle bwains suffering from "psychic overpressure" because the United States had a REALLY good day in the War On Terror and they have to face the fact that we ARE going to win it...

[Pukin Dog]

It just works, baby.

[Aggie Mama]

I heard the general say that too. I expect the gory pics & video will be on YouTube within the next week.

[COEXERJ145]

IIRC, that house was part of shot Teapot Apple-2 which was a civil defense structural effects test.

[IronJack]

This creates such a lovely, enchanting scene ... one I can play over and over in my mind as I hum The Battle Hymn of the Republic and watch the liberals implode in impotent fury.
