lol first of all wellcome back reporter, i missed you.ok a klub missile is a russian built anti ship anti submarine missle(n.a.t.o name ss-n-27).it's the state of the art modern missile capable of destrying any modern stealth ship or submarine, it's the only one of its kind in the world, here i'll give you the link to it,

Have you tried the Pressurised Bottle Rocket?\n\nEasily constructed with used plastic bottles. What you need is a pump, cork and a tube. Build some tail fins to stablise the rocket for flight. You need to put in some water in the bottle. Then just pump the pressure up and you have an entertaining setup.\n\nHave a challenge who can shoot the highest and then parachute the Rocket down. The highest and/or the longest hang time wins.\n\nYou will need a field to do this properly though.

there is a laser,invented at the time of the cold war, i think in the 80's, it interfears with the rocket's laser targeting device,for example a tomahawk wont find the target an i think she will selfdestroy,but that laser gun was interdicted.I heard that exist an laser gun that could destroy an rocket,i heard about an experiment with the russian 2 war's rocket KATIUSHA,two of those rockets were destroyed.

Friend you know that the missile Brahmos is jointly developed by Russian and Indian Engineers and only supersonic missile in the world. \n\nBrahmos = Bramaputra + Moscow

I'm going to go ahead and contradict everyone else here. (Girlnextdoor, it sounded good, but prepare to be enlightened.)\n\nFirstly, there are huge holes in the ozone layer. Anyone look at a satellite picture of Africa recently? It's a little scorched and brown. Why do you think the Sahara Desert is getting bigger? The biggest hole is positioned directly over Africa, but is slowly moving towards South America.\n\nSecondly, it is possible for rockets and missiles to put holes in the ozone layer, but as someone else stated, these holes close immediately because ozone is a gas. It is plausible that some ozone is burned off when a rocket comes tearing through, but it's nothing life-changing. \n\nAnother point I would like to make is that when oxygen is emitted from rockets, it will not help the ozone. this is because the oxygen emitted from the rocket is O2, while the chemical formula for ozone is O3.\n\nSo, to answer your original question; yes it is possible, but it is very unlikely. Oh, and by the way, it will take thousands of years, not a few weeks for the CFC's to clear up.\n\nSide point: Did you know that ozone is actually poisonous? Yep, don't breathe it. You'll die.

But JumpingJack we do not sell to the terroist countries like the russinas do. where do you think (Iran Syria just to name a few) got these reactors and stuff. They don't have the technology or the scientist, or material, so more than likely some corrupt Russian offical sold them.

The liquid oxygen goes in the smaller, top tank inside the external tank.  To provide better stability in rockets, one should always put the densest (and heaviest) fuel at the top.\n\nThe propellant mixture in each SRB motor consists of an ammonium perchlorate (oxidizer, 69.6 % by weight), aluminum (fuel, 16 %), iron oxide (a catalyst, 0.4 %), a polymer (such as PBAN or HTPB - a binder that holds the mixture together, 12.04 %), and an epoxy curing agent (1.96 %).

i believe they are rockets launched just prior to the explosion. They give us an idea of how fast the explosion is expanding. hope this helped. :)

Ca(s) + 2HCl(aq)-->CaCl2 + H2(g)\n\nor...\n\nCalcium Chloride and Hydrogen Gas... you know... the stuff that fuels rockets! :)

I really don't know about the case you are referring to, but it remembered me a recent collision (April 1st, 06) between a Russian satellite and what they think was space debris. Looks as if this accidents will be every time more frequent as the number of satellites and debris increase. \n\nCheck the link to see the news:\nhttp://skymania.blogspot.com/2006/04/collision-knocks-out-satellite.html

Environmental groups have recently voiced concern that exhaust from the space shuttle and other rockets could harm the protective ozone layer. But measurements taken by satellites after shuttle launches do not show any sign of stratospheric ozone destruction, atmospheric scientists report.\n\nSolid-propellant motors used to loft some rockets pose a potential threat to the ozone layer because their exhaust contains chlorine, which in some forms can destroy ozone. Indeed, a scientific flight through a rocket's exahust plume in the 1970s detected a 40 percent decrease in ozone levels in the plume, reports Steven Aftergood of the Washington, D.C.-based American Federation of Scientists in the Sept. 20 JOURNAL Of GEOPHYSICAL RESEARCH. Aftergood suggests that launches may produce local ozone "holes" that persist for several hours.\n\nIn the same journal, Richard McPeters of NASA's Goddard Space Flight Center in Greenbelt, Md., and his colleagues respond to Aftergood's comments by examining satellite measurements of ozone in the shuttle launch area. They find no detectable ozone decrease after several launches.

I dont think they were actuall M203's, they were a smaller diameter and I think they were available with a chalk type and maybe a smoke projectile.  Did find a 37mm flare launcher\nhttp://lgweaponry.com/ad_sheets/37mm.htm
