These barrel bombs contain up to three ...Precisely. These barrel bombs contain up to three quarters of a ton of TNT, the Baltic Exchange bomb was a larger quantity of a weaker explosive. Somehow "throwing" (toppling is more likely) such a bomb off the top of a building guarantees that building will collapse.<br /><br />A propane bottle of explosive has a fraction of the power of one of these barrel bombs. The whole point of the article was that these are very big barrel bombs.<br /><br />The point emerging from the videos and comments is that the explosive materials used in their construction are indeed identical to those used in a truck bomb, found in the water tank of what appears to be a fire engine or water truck.<br /><br />Your link pertinently puts the explosive content of a metre-long propane cylinder at 70KG, which is about a tenth of these barrel bombs. Even that would be a difficult and dangerous thing to chuck off a building, so I presume the rebels used smaller cylinders in the main. 20Kg would probably be enough to destroy a tank if it exploded on the thin armour of the turret roof or engine deck.<br /><br />It's also worth noting that the Lynx helicopter "shot down" by the barrack-buster was hovering over a predictable point (the helipad) at the time, and that the fuse of the projectile appears to have set it off on the ground afterwards: the damage was all done by the kinetic energy of the cylinder and the stored energy in the spinning tail rotor system. The crew survived and they would not have done had the cylinder exploded on impact with the Lynx. <br /><br />The element of luck involved, even with a hovering target, was pretty considerable and more often they missed by a long way. Which is why local nationalist politicians were so angry about the action.Medawarhttps://www.blogger.com/profile/05119173935699236303noreply@blogger.comtag:blogger.com,1999:blog-4871088750473093560.post-67433650151107879452013-11-26T14:27:16.585-08:002013-11-26T14:27:16.585-08:00The Baltic exchange was a truck.

Also, TNT and most other raw high explosives will start to darken up when exposed to the open environment/elements. The longer the explosives are exposed to the elements the darker they will get. Additionally, this exposure will cause the explosives, if in powdered form, to start to stick together/chunk up. Cast explosives (like TNT blocks) or pressed explosives will also darken up and become brittle. If your take a block of TNT that has been out in the elements for awhile and break a piece off the surface of the block, the unexposed TNT will be a much lighter color then the outer exposed TNT surface.Anonymoushttps://www.blogger.com/profile/01718716337874488769noreply@blogger.comtag:blogger.com,1999:blog-4871088750473093560.post-23338882437157591332013-11-23T07:57:18.046-08:002013-11-23T07:57:18.046-08:00I had grasped that the knots were simply a way of ...I had grasped that the knots were simply a way of concentrating detcord to make a booster. The IRA would have wrapped the knot in a little semtex. (This comes in both PETN and RDX forms, the PETN one being white.)<br /><br />There are two hatches, and there seems to have been detcord and black boxes in both. Fill is a foot or so below the hatch at one point, deeper at the other.<br /><br />I think the mobiles phones that appear in the man's hand later (with masking tape labels presumably with the number to call) must have lived on the outside of the steel tank, perhaps with an earphone cable going to the black boxes inside the tank? <br /><br />I cannot see a mobile inside the tank getting a signal of any kind. (Rather like the US TV special forces drama which showed commandos operating a hand-held GPS inside a submarine, this ain't going to work.)<br /><br />The powder looks darker in one of the UXB videos than it does in the truck bomb video. If that implies an RDX content, then there's enough of it caking the expert's hands to be a toxic risk. (Straight TNT is surprisingly non-toxic, because it's so insoluble in water that it doesn't get into the bloodstream in the same way.)

There is one other key explosive item there (electric detonator) but you can't see it. Another clue, note the location of the black box/s. You will have to figure the rest of this one out on your own, sorry.<br /><br /><br />Also, when time fuse is knotted or squeezed/pinched the powder inside is compressed and yes it does burn faster. Also, when time fuse is used under water the same thing happens. As the depth increases so does the external pressure on the time fuse and it will burn significantly faster the deeper it goes ( I have lots and lots of experience in these areas). Additionally, don't confuse the ULI knotted det cord with time fuse, as seen in most of these videos. A ULI knot (or other det cord knots) is a deliberate attempt to turn a section of det cord into a booster and it shows that these folks have some level of basic demo training.Anonymoushttps://www.blogger.com/profile/01718716337874488769noreply@blogger.comtag:blogger.com,1999:blog-4871088750473093560.post-14723345470498761702013-11-23T04:16:28.244-08:002013-11-23T04:16:28.244-08:00Your video shows a new type of UMLACA at 0:11.

Do we know if the cameraman made it, or the helicopter?<br /><br />Nicely illustrates the essential problem with miner's slow fuse and airdropped munitions.<br /><br />There was a Hornblower short story about blowing open a sunken wreck with a barrel of gunpowder: this is the equivalent of the "flying fuse" which Hornblower and his men are trying to avoid using. As I understood it, a flying fuse is a length of cannon fuse in a rubber pipe, which can burn faster or slower if the fuse is twisted loose or twisted tight. <br /><br />I'm not sure if there's anything on the internet about this, but I've read printed articles in pre-internet days about slow fuse becoming really quite fast fuse if it gets untwisted.

In that case, not very plastic at all. Note that there is another munition of some kind at the back of the garage. Backing away from the man with the hammer would have done no good as he was bashing the booster charge out next to pile of powdered explosive. Bless.<br /><br />Jody Wave:<br />I see: TNT in powdered form intended to be moulded into a cast charge, but used au naturel. An awful lot of it, and several blue barrels. (The IRA always liked blue barrels, too, but plastic ones. That's because they were actually concerned about the safety of bomb-makers, which doesn't seem to be the case here.)<br /><br />Jody second vid:<br />That's a truck bomb they are sitting on! A huge one in a strong steel box. Like Liddel's main charge in HMS Cambeltown for operation Chariot. I think the big steel box is actually the water tank for what looks like a small fire engine.<br /><br />This suggests a variation on the "two bomb" tactic where one small bomb attracts emergency responders only to be killed by a bigger one: small bomb creates fire, "fire engine" drives into secured area to put out the fire: bang!

Also, you can see lots of white sticky/powdery (?) material coating the det cord ULI knot. This white stuff may be residue from an additional booster charge (plastic explosive or something similar). If this is the case then the ULI knotted section of det cord would have been imbedded inside this other type of white colored explosive. <br />http://www.youtube.com/watch?v=EeQAtRAIQu0&feature=player_embeddedAnonymoushttps://www.blogger.com/profile/01718716337874488769noreply@blogger.comtag:blogger.com,1999:blog-4871088750473093560.post-14328128925545490992013-11-22T12:02:24.851-08:002013-11-22T12:02:24.851-08:00Blocks of what might be TNT/ammonium nitrate?

Filling was 3,000lb of Amatol.<br /><br />Worth noting, re fusing, that whereas artillery shells have big forces available on firing to work an arming mechanism, air dropped bombs don't and this is a problem. The release mechanism has to do more than let go, and this takes a bit of engineering. (WW2 German bombs usually had electrical detonators, probably for this reason. UK and US bombs generally had mechanical fuses, which took significant industrial effort to make.)<br /><br />I would think that for the barrel bomb to have genuinely safe fuse, it would need to have a properly-engineered and tested release rack capable of all the coordinated actions. Which would be more work than the bomb, though it may appear in a few months time as it's an obvious next step.<br /><br />The 4,000lb HC is also notable for flying straightest when fitted with a slightly domed nose spoiler and drum tail: a conical nose spoiler, although thought more streamlined, was not stable. This is may refer us back to the big rockets and their aerodynamics, discussed recently. Being stable helps range for a rocket as it keeps the thrust in the right direction as well as drag being more for something traveling sideways.<br /><br />I think this means a similar sized barrel bomb would have a blast radius of ninety or so yards, though debris coming out of the area might be lethal very far away.Medawarhttps://www.blogger.com/profile/05119173935699236303noreply@blogger.comtag:blogger.com,1999:blog-4871088750473093560.post-9078486381881482652013-11-22T09:34:22.086-08:002013-11-22T09:34:22.086-08:00They dropped another one today, with another look ...They dropped another one today, with another look at the fuze<br />https://www.youtube.com/watch?v=AommAppV0Zs&feature=youtu.be<br />https://fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-frc3/1403206_522607801167995_708773427_o.jpgBrown Moseshttps://www.blogger.com/profile/17562126209980810351noreply@blogger.comtag:blogger.com,1999:blog-4871088750473093560.post-39378651742829724402013-11-22T08:12:46.973-08:002013-11-22T08:12:46.973-08:00Medawar, This barrel bomb may very well have multi...Medawar, This barrel bomb may very well have multiple nose fuzes since it appears to have three potential fuze wells in its nose plate assembly.

Detonating Cord; The central core color of exposed/cut ends of det cord will have a white or off white color. Typically det cord branch lines will be connected together with tape, knots, or clips/connectors.
