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

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.

Yeah but that is like Lot 28 and up? (AESA) Ours are not. But, I was trying to appeal to Pukin Dog's F-14 roots.
I'd have to check...a SH beats a TC in speed? What, stripped?

Oh, and I forgot ours (F-14Ds) were carrying LANTIRN pods. "Ours" being in the airwing; I went from Phantoms (a REAL fighter - attack aircraft) to Hornets way back in 1986.

Here's another for your photo essay:
"The hard part was inventing the Candygram!"
To: Pukin Dog
Agreed, and a lot has to do with the material structure, location at the time of blast, etc. Far too many variables for someone to simply dismiss as the DUs are doing as being staged.
I've see blasts do really weird things. Blow a house down but only crack the glass in the window.... Totally rearrange a room but leave a picture hanging on the wall....

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. It's called "not letting the facts interfere with your previously concluded opinion" -- A malady that is by far disproportionately represented among Liberals (refer to Ann Coulter's latest book for details).

Al Jazeera claims showing the photos of him dead is a violation of the Geneva Conventions! And what exactly is their position on showing innocent people on video being decapitated by these subhuman monsters?
Nevermind. I know the answer. And my personal response to Al-Jazeera is this: "Your time is coming too, you scum of the Earth. Just wait and watch. WE, THE best PEOPLE on the planet, are most certainly coming for all of you."

The picture didn't come through. I'm getting a little red x.
Try and again and ping me when there is a picture.

The SH with it's range, payload (nearly an A-6), ATFLIR, AESA, high degree of survivability........ makes for a ferocious CAS/IA platform.

5 psi overpressure at the Nevada Proving Ground in the 50's. Don't mess with rapidly moving air. I bet that parted his hair. :O)

Also, when the Z Pig entered hell, he found out that his 72 virgins were clones of Helen Thomas. They are having their way with him now.

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. his face was probably peeled off a wall and stuck on ball for the pics.
too bad...so sad...

That was back in the day when Olbermann was cool. When was that? Before his runaway eyebrow growth severely restricted the blood flow to his cranium?
