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.
FAE is the best
Russians call them 'Therombaric weapons'
Same thing, dynamic over pressure.
Actually, what you obviously need is a good ol' Viper with an actual Red Blooded All American Boy at the controls. That...and some of the meanest, most heroic snake eaters in the world rooting around in the weeds looking for suitable targets.
; )
Thank you, this is just what I needed!
Can anyone give me a link to the MPEG download?
I still have not seen the actual MPEG.
Thanks for posting that. I'm looking for the one where someone tickles the body of Che, and his feet move.
My point earlier was that there is a lot of know-how, science, and planning that goes into all of this. Even a standard Paveway, a lightning or sniper pod, etc. is pretty impressive if you think about it.
Another example: If you go to BIAP there is a Mosque (with a blue roof) nearby. Close to this Mosque the former regime built Republican Guard complexes on two sides. The idea is that if you want to bomb those Republican Guard facilities you have to damage if not destroy the Mosque as well. The Mosque is untouched! On both sides (And I literally mean just yards away) BOTH Republican guard facilities are pulverized. Nothing but heaps of rubble. If you drive just 2 miles and go to the West side of BIAP where the old aircraft bunkers are at you’d see that every single one has a nice hole in the roof. Nice clean hole with no misses (No craters except in the bunkers). These bombs punched through about 3 feet of concrete, 9 feet of sand, and then another 2 feet of heavily reinforced concrete. Judging from the mess inside the bunkers, nothing survived that. The sides of the bunkers are well sloped and even the few bombs that didn’t exactly hit the center roof still detonated hitting the side slopes. Very impressive to say the least.
The point I’m making is simple. There is a high degree of planning, a lot of science, training, money, experience (lessons learned) behind this. Those planes that busted those bunkers probably were carrying something very different than the plane blowing up the Rep. Guard facilities. The building (4 or 5 story) that had its entire guts blown out but all the walls still standing in Baghdad that I saw, probably was not hit with the same ordinance and most likely delivered on the Republican Guard Facilities near BIAP.
They marry up the appropriate airframe to the mission, load it out with the ideal ordinance for the effect desired, and then deliver this ordinance in a manner to maximize what it is they want to achieve. In some cases, as in 1991, they actually custom manufacture ordinance for a specific target. Just think about the complexity in the whole targeting process, developing target folders, determining BDA, logistically supporting those planes, assuring the right quantity or ordinance is present at the right place in time, maintaining the planes, and and and……. It's all quite impressive.
hehehehe
.........Worst Job In the World: "Cleaner" for Zarqawi........
Maybe you could use the Bounty tissue that was just used to drain the bacon fat!
Z was in the basement with his lieutenants. I figured he was killed/crushed by the concrete house falling down on him. That the over pressure was blunted by the time it reached the basement
EXcellent idea!
Not that it matters to me what happens to this POS...but who claims the body and what happens to it?
Can the US provide a happy resting place for him in a pig sty? Just wondering..
I'm still waiting for you to tell me that the JSF is not being built, or that it's behind schedule, or that it's by design going to fail. Should we go back to those posts by you?
Not as nice as when shrapnel from a howitzer round slices and dices him, but "that'll do, donkey, that'll do!"
