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.
Oh, dont be saying that, poo.
It only pisses off my detractors. LOL.
Thanks.
Steady on there, girls.
LOL!!!
Really a treat for my Friday lunch hour
Thanks guy.....

I'm glad Zarqawi lived for a little while after the blast. Instead of being instantly blown to bits - where he wouldn't have known what hit him - he lied there, dying, aware of the presence of U.S. troops at the scene. Knowing 'we got him' - knowing he lost - knowing his time in this world was over and that he would never be able to saw the head off of another innocent non-Muslim human being again.
That was justice!
Oh I don't know about that, they stink bad enough when they are alive. After a day out in the heat.. be quite a stench I would imagine.
Now the smell of Tritonal, Minol II, or H-6, which are the explosive filler in the MK-82 500 lb bombs, that's sweet.
Especially one with a muzzle brake.
I once attended a firepower demo at Ft. Sill, back in the dark ages when I was an AF Lt. One demo was a flight of 4 F-105 Thunderchiefs from the AF Reserve at Bergstrom in Austin Texas. They were each loaded differently. One had high drag bombs, one had cluster bombs, one had napalm (very impressive!). The other one had a couple of 2000 lb low drag bombs. He dropped them one at a time, one in a dive bombing maneuver, the other a "dive toss". The nearer of those was a good 1 to 2 miles away. It felt like catching a medicine ball thrown by Lou Ferrigmo, right in the center of your chest. Umpf!
The Army's artillery was pretty impressive as well.
I end something a little more derogatory next time.
I end = I'll send
Payroll was a little hectic today.
You should not post in a public forum if your don't want people to post to you.
Well,
I might not know the personal biography of Rokke, but I do know what you are not.
And you are neither a pilot, nor were you in the military, and you surely have no clue about the JSF. Please feel free to correct my analysis of you. After all, you might have taken a class in aerogami.
I know in grade school they have cut into English programs, so I’ll make it easy for you.

Why can't we be kind like the liberals...................let the baby be carried to term, deliver the baby feet first until just the head (face down) remains in the womb, insert a long, sharp, shaft-like object into the base of the baby's skull and continue to thrust up into the brain (causing the baby's body to jerk sharply), now, use the shaft-like object to ream a hole large enough for insertion of a vaccum hose in order to suck the brains out, finally, complete the deliverly of the otherwise fully developed baby................
It's called a Partial-Birth Abortion............... one of the sacraments of the Godless Church of Liberalism.
bump to save
Stuned his beeber real good
Possibly not, though. He was stuned then his beeber was gone.
I will use the excellent comparisons you made the next time some stupid liberal makes the mistake of telling me how heartless WE are! Thank you!
Be my guest for all the good it will do. "liberals" never listen to logic or reality. They just don't get it. They're deaf and blind.
"Sorry Zarq, we're fresh out of virgins. All I can spare are two sheep and three-legged camel."
I agree. The technology is unbelievable. And the fact that an attack like the one on Zarqawi was actually routine shows how far we've come. Not only that, but since the technology used is actually decades old, one can only try to imagine what exists in the more secret world that doesn't make the news. Less than 60 years ago we needed to destroy cities to eliminate a single target. Now we destroy single targets to save cities. When you can achieve your objectives with almost no risk to your own assets and without creating a pile of rubble that you will eventually be paying for in one way or another, you have raised yourself to a new level of warfare. And the side that makes that raise first, holds all the cards. Fortunately, we are on our way, if not already there.
