"Liquid Explosives"

OK, I've read some of the articles and such about liquid explosives from the BBC. They all allude to some vague, nebulous ingredients that might be able to be combined to make a liquid explosive, or combining a liquid and a solid.

They read like bullshit, as in, as credible as "red mercury" being a nuclear material.

Yes, there are liquids that can be combined to make explosives. In order to get explosives out of these, they have to be highly concentrated. Some are considered "volatile". This means they stink.

Take acetone, a well known ingredient in nail polish remover. The concentration is low, the smell is high. If someone decided to "do their nails" on an airplane flight, they'd get lynched - that shit is vicious in an enclosed environment.

Or various acidic drain cleaners: hard to handle and package without burning yourself, or sufficiently low strength to not do anything more than fizzle. These stink too.

Hydrogen peroxide: the stuff you can buy in the drugstore is low concentration. It would have to be concentrated (not a simple process), then repacked in the original bottle. It smells when you open it, too. Hair bleach developer has a slightly higher concentration, but again has the smell problem.

Gasoline/Fuel oil: first, it smells; second, its already prohibited in aircraft cabins.

So, basically, it would take a lot of effort, coordination, and ingenuity by the terrorists, plus gross apathy on the part of their fellow passengers. Ain't gonna happen. Not when passengers that look like they *might* be doing something funky get tackled promptly by fellow travellers.

I am sure your degree in chemistry, organic or otherwise, serves you well in this reguard.

Every single one of your points about smell or notice, is voided by simply -sealing- the container before you bring it to the airport. NO smell from a sealed container. I only need 10 seconds to detonate just about anything, really.

At least get off the high horse of 'OMG SO INCONVENIANT!'. They were, according to the reports I read, just a few hours away from actually putting the plan in to action. OBVIOUSLY someone with a bit more education in chemical sciences than either of us thinks it was credible enough to put three nations on alert and utterly inconveniance thousands of travelers.

But you can still take it on your checked luggage. So how is it any safer to stop people from carrying on in a bag? This is another band-aid effort that doesn't really increase the "security" of flying.

[identity profile] koga.livejournal.com 2006-08-11 12:12 am (UTC)(link)
The answer to that is fairly simple.

The key to carry on baggage is the ability to reassemble a disassembled IED in to an actionable state. This lets me sneak what would be obvious aboard in an inobvious fashion. Each IDE typically has 4 componants. The Trigger, the Timer, the Power Source and the Explosive. In a dual charge mixture, you have two explosives, a trigger and a powersource. Timers not needed as its directly triggered. This is the entire reason for carry on searches, to root out one or more componants.

As for the checked in luggage:

Checked in luggage, every bag, is swept for explosive compounds. Further, it is subjected to an examination more akin to an MRI than an Xray, with slices of a bag examined ever 1-2 inches, thereby cutting a standard bag in to 20 or more images to be viewed. The problem wiht checked in luggage, is the item to explode must be able to explode with no further human contact, IE: Assembled and ready to go. This will be detected by the above scan.

If anything looks even vaugley suspicious, its pulled out.

BTW, they still don't have 100% baggage screening via MRI, IIRC. The funding for sufficient machines never came through...

[identity profile] ravan.livejournal.com 2006-08-11 12:49 am (UTC)(link)
...screening via MRI...

Or whatever they are calling the technology. I haven't read up on scanning technologies in a couple years.

THats true. And thats where most TSA employees are working: Manual bag-checks.

[identity profile] ravan.livejournal.com 2006-08-11 12:21 am (UTC)(link)
You can't combine the ingredients without opening the container. Two ingredients uncombined in sealed containers are harmless.

The chemical reactions needed to produce explosives are not instant.

OBVIOUSLY someone with a bit more education in chemical sciences than either of us thinks it was credible enough to put three nations on alert and utterly inconveniance thousands of travelers.

Actually, I doubt that anyone with any realistic knowledge in this area was involved in the alert.

The alert serves a political purpose, not for the alleged terrorists, but governments who want to "boil the frog" by slowly aclimatizing us to more and more invasive surveillance and restrictions.

Maybe it's credible, but I doubt it. These people's track record sucks - "red mercury" anyone?

This is incorrect in many cases -- remember that the Oklahoma City bombing was done using fuel oil and ammonium nitrate. The liquid and slurry explosives are just a mechanical mixture of a fuel and an oxidizer; no chemical reaction is needed -- except for the final one, of course.

And there are chemicals like caesium and rubidium that explode on contact with plain water. There's a video on the web somewhere; probably YouTube.

[identity profile] ravan.livejournal.com 2006-08-11 05:00 am (UTC)(link)
Metallic sodium burns with almost explosive intensity. But it's also not a common chemical.

IIRC, there are only a few liquids that when combined are instantly explosive. Most go through a reaction (often exothermic, which is what makes playing with boombooms fundangerous) that isn't quick and gives off nasty fumes.
mdlbear: blue fractal bear with text "since 2002" (Default)

[personal profile] mdlbear 2006-08-11 05:47 am (UTC)(link)
Ceasium is significantly more reactive than sodium, which is the mildest member of the family. Sodium burns, potassium burns vigorously, rubidium explodes, and caesium explodes violently. The video in question shows the result of dropping a couple of grams of caesium into a cast-iron bathtub of water. The tub is shattered.

The liquid/slurry explosives are quite inert, even after they're mixed. No reaction at all. (Most emphatically not like making nitroglicerine.) It's a lot like mixing hydrogen and oxygen. They're very stable until they're hit by a shock wave, e.g. from a spark or a sharp impact. At which point they detonate, the way any other high explosive does -- the energy of the reaction forces the shock wave to travel supersonically. That's the definition of a high explosive.

Also, I don't consider risks to health and sanity merely "inconvenient". Dehydration and food poisoning are not just "inconveniences", they are serious health matters, and can have a long term, cumulative effect.

As far as I'm concerned, air travel while disabled was already enough of a PITA that I drove to Seattle rather than fly and put up with the phoney security. It's 1,000 miles from here.

Now my drive v.s. fly threshold has increased. The car rental is cheaper than bail, after all.

I refuse to succumb to the senseless paranoia and overblown hysteria - I won't "play along" with it. Reasonable precautions are one thing - but this crap went past reasonable years ago.

[identity profile] koga.livejournal.com 2006-08-11 01:37 am (UTC)(link)
Yeah. Right before the planes flew in to buildings and random farmland because 19 kids had boxcutters?

Look, you want to be rightiously indignant that YOU HAVE BEEN PUT UPON.. you go right ahead.

But remember, travel by air is a fucking privilage, not a right. You want to drive, do that. Take the train. But air travel ain't exactly in the constitution. You're off base and you're ill informed, worse, you show absolutly no interest in actually observing information put in front of you, instead relying on what you =know= to be true.

Just like any other christian fundimentalist.

...travel by air is a fucking privilage, not a right. You want to drive, do that. Take the train. But air travel ain't exactly in the constitution.

So the ability to travel by a particular mode is a priviledge, not a right if it isn't mentioned in the Constitution? Guess what? No mode of a right to travel (by any means) is mentioned in the Constitution. From usconstitution.net (http://www.usconstitution.net/constnot.html). But, note the following:
The Right to Travel

As the Supreme Court notes in Saenz v Roe, 98-97 (1999), the Constitution does not contain the word "travel" in any context, let alone an explicit right to travel (except for members of Congress, who are guaranteed the right to travel to and from Congress). The presumed right to travel, however, is firmly established in U.S. law and precedent. In U.S. v Guest, 383 U.S. 745 (1966), the Court noted, "It is a right that has been firmly established and repeatedly recognized." In fact, in Shapiro v Thompson, 394 U.S. 618 (1969), Justice Stewart noted in a concurring opinion that "it is a right broadly assertable against private interference as well as governmental action. Like the right of association, ... it is a virtually unconditional personal right, guaranteed by the Constitution to us all." It is interesting to note that the Articles of Confederation had an explicit right to travel; it is now thought that the right is so fundamental that the Framers may have thought it unnecessary to include it in the Constitution or the Bill of Rights.
So, essentially, it's not written in to the literal Constitution, but "it is a right broadly assertable against private interference as well as governmental action. Like the right of association, ... it is a virtually unconditional personal right, guaranteed by the Constitution to us all." Please note that no mention is made of the means of travel. There is no differentiation between car, bus, train, plane, or bicycle. Either the right to all exists, or none. I would say, based on the above, that the right exists to travel by any means you can afford. You're now spouting statist nonsense.

You're off base and you're ill informed, worse, you show absolutly no interest in actually observing information put in front of you, instead relying on what you =know= to be true.

Ah, yes, when you have no facts or logic, nor even precedent to back you up, resort to ad hominem attack. Please notice who could make use of a simple search engine, and provide at least a few unslanted citations for my position.

Just like any other christian fundimentalist.

Sorry, but your position is the one of the christian fundamentalist: advocating submission to authority as frightened, terrorized sheep. State or priest, what does it matter? Sheep are sheep.

The presumed right to travel, however, is firmly established in U.S. law and precedent.

Hey, guess what?

It is emphatically the province and duty of the judicial department to say what the law is. (from Supreme Court ruling, Marbury v. Madison)

Who knew? The Supreme Court says that there's a separation of powers. OK, they said it once upon a time... we got a bunch of pansyarse rubberstamp motherfuckers on the bench now. But it's still the law.

Sheep are sheep.

And along with sheep and wolves, there are sheepdogs. Fear the dawg. ;-)

TRAVEL, according to the various powers of government, over centuries of experience, is a priviledge, which MIGHT be accorded to the populace, but don't bet on it. And travel, by car, boat, mule, or foot, isn't in the Constitution, either.

Lack of right and means of travel was quite effective in the old Soviet Union in keeping the populace controlled. Not safe, controlled. I've been predicting since the 1970's that we will be in trouble when we start seeing more and more restrictive regulations on travel, more than anything else. It's nothing big. It's just a few steps, and a few more... "That's how freedom will end, not with a bang, but a rustle of file folders..." as someone said on the net around 1990. Go head, call me a conspiracy theorist. People have been doing it since I was in high school. But things I predicted then have been following a progression that matches certain patterns from past political situations. I don't know, maybe I just know too much about the Bolshevik Revolution, the Maoist government, and the French Revolution, and the Tokugawa bafuku, and... It's been proven, time and time again, through history, throughout the world, it's one of the most effective ways of controlling a restive population.

Easy enough to do the mixing inside a plastic bag.

Of course the next trick will be little sealed two-component bombs that do the mixing and detonation inside a checked suitcase.

Oh, and H2O2 is pretty easy to get or synthesize, though it's tricky to handle. Ask any rocket hobbyist.

And of course powdered aluminum and air will do just as well as acetone and H2O2.

Or prescription meds capsules with anthrax in them instead.

The tricky to handle is its downfall.

Yeah, and the restriction on liquids won't effect that.

Hell, if you want to be an ass, take a small bag of flour, go into the bathroom, block the vents, then get the really well into the air, and then strike a spark. You might get a dust explosion, IIRC. If it fails, it's easy to clean up.

"without fumbling or being noticed?"

Easy -- do it under a blanket. Anybody who's ever taken 35mm film out of a roll in a changing bag could do it with a little practice. Or put their ponytail in a rubber band behind their back, for that matter.

H2O2 is fairly tame as long as you don't let it get in contact with somethng that will catalyze its disintegration, which is highly exothermic. They discovered during WWII that solder falls into that category. Plastic, however, is just fine.

What pisses me off the most is that all they have to do is announce that they've foiled a plot, and therefore we are all simultaneously saved and subject to further bullshit.

Show me, don't tell me.

They (all the coalition of the killing) have been "thwarting" plots ever since 9/11, yet we've seen no legitimate judicial action based upon these claims.

Why was the announcement not made after arrests, charges, evidence presented in a court of law, and a verdict?

If it was such a brilliant plan, why didn't these trrrrrrrrrrists infiltrate the employee rosters of airport vendors and suppliers, to coordinate shipment of the inert substances to different airport bars/restaurants, and then disperse them on D-Day to the psycho mofos who would then combine them in the damn loo onboard?

"I'd like the extra-special daily special."

How hard is that?

Not very. Sleepers are a far more insidious threat. If you are patient, you can have several of your agents get jobs with concessions, and then years later use them to provide materials. They don't have to have flight line clearance - just concessions. But they can smuggle small amounts in over several weeks. If you have them all working for different vendors, there's less chance of them being found out. Have two or three for each component. Better yet, have the ones with component 1 at SFO, component 2 at ATL, and component 3 at JFK. Get on an international flight from there.

That's why I don't believe this crap about liquid explosives and sports drink containers. It's too contrived.

Hell, liquid plus powder is more believable.

And don't forget, this is an election year. Congress is out of session until September 5, when they will do nothing for a month, then adjourn so they can go fight to keep their seats. Coupled with the fact that the Bush administration was privy to the investigation all along, it seems all the more contrived.

Hey, America, look what we've been doing to keep you safe! Now pay, and obey.

I can think of two that I know of which could do major damage quite easily. One is a length of sodium based phone cable --- just put it into water in an enclosed space and wait for it to blow and it will blow, big time. The other is to simply have some pool chamical and pour DOT #3 brakd fluid on it --- Boom and fire! either of these could be done under that blanket or in a bag and only one of them is really liquid in each pair. There are others and the problem is detecting which liquid would be used for the catalyst and with which solid. I guess someone figures that eliminating the liquids and gels will eliminate at least half of the possible equation. Actually I think this ban makes a whole lot more sense than the nail clippers and crochet hooks! But then, we crazy VFD folk tend to be more aware of what will smoke, boom and burn more that what will poke, prod and cut.

I think the guy that called you a fundy christian was hilarious, so little does he know of you. Can I tell him that you have been a practicing pagan for some thirty years or more? May I, huh? LOL He also doesn't know, obviously, that you worked for many years in a chem. lab. Just shows to go ya, how quickly people are to assume when they disagree with one assertion that someone must be of a certain philosophical bent to have an opinion different from theirs. Peace, hugs and chocolate to you and to Datapard too. Tandala

[identity profile] ravan.livejournal.com 2006-08-11 05:12 am (UTC)(link)
Yeah, but sealed bottles of water purchased inside the sterile zone??

One is a length of sodium based phone cable...

Oh, cripes! I thought they phased that crap out years ago and disposed of it properly. That's just an fire waiting to happen.

... have some pool chemical and pour DOT #3 brake fluid on it --- Boom and fire!

Both of those stink (depending on what the pool chemical you're thinking of is), and are nasty to handle.

Let's just say my parents never realized how cautious I was when playing chemistry in junior high and high school, and I still ended up with some very exciting and stinky reactions... I stayed away from trying to make explosives in the house because I didn't want to scare the dog.

Sodium isn't reactive enough -- it'll burn, but not explode. Put a gram or two of rubidium (list price about $30/g) in a soluble capsule. Order a glass of water from the stewardess. Drop it in and put the glass down by the window. Boom.

[identity profile] jemyl.livejournal.com 2006-08-11 11:03 am (UTC)(link)
Sorry, but I have personally seen the results of a sic inch piece of phone cable (which our instructor told us was filled with sodium) placed in about a gallon of regular water in a five gallon plastic pail with another pail wedged down in it explode and send the "cover" pail 35 ft in the air and destroy the first pail completely. There is still a lot of that old phone cable in use as it is only replaced when it wears out because of the cost to find and replace all of it. This little explosion was part of our practical demonstration on the last day of our Hazmat training class.

[personal profile] mdlbear 2006-08-11 03:15 pm (UTC)(link)
I see where we differ. Sodium, because it burns quickly, will explode if confined. Rubidium and Caesium will explode even without being confined. A gram of caesium dropped into an open bucket would destroy the bucket on contact. It's not common, but at $30/g it's not all that hard to get.

I'm not chemist, but I know a fair bit about this subect.

1) Not all chemicals that combine to make a high explosive. I can think of three right off the top of my head, that I personally know how to make or have made. Two of them use essentially odorless, colorless components. One of them is inert when wet, unless exposed to a mild explosion of some sort (say a shotgun shell primer, some phosphorus, etc. But again. easy.

2) I don't make a habit of going through this stuff, but I can think of at least three or four totally innocent looking delivery systems that would get you on an airplane.

The point here is that yes, most of the obvious choices would not be practical. But never underestimate the patience and ingenuity of a couple reasonably bright people to find an angle.

The point here is that yes, most of the obvious choices would not be practical. But never underestimate the patience and ingenuity of a couple reasonably bright people to find an angle.

Yes, most obvious items would not be practical, yet the new regulations seem geared toward them.

Also, the patience and ingenuity angle would argue for the next logical extension of the total safety policy:
1) No carry-on possessions except travel papers as issued at the airport secure zone.
2) No clothing allowed aboard. Paper jumpsuits issued by the airport.
3) No leaving your seat. Adult sanitary underwear will be issued, and seatbelts will be locked by the staff upon boarding, and until it is time to deplane.
4) All luggage, paperwork, and clothing will be inspected and sealed aboard a different cargo flight.
5) A body cavity search and x-ray will be performed when you check into the sterile zone - no fuses sticking out of people's asses. This also helps fight the War on Drugs(tm).
6) Any required medication requires a doctor's written prescription, and will be filled at the airport and administered by the airline staff.

This is about the only level of security that I can think of that will eliminate all of the ways I can think of to try to smuggle explosives or chemical weapons aboard.

However, even with this, wait a few years and they will have sleeper agents infiltrated into the ground crews and airplane staff (assuming anyone still flies). Either that or they'll start blowing up ports with the under-regulated cargo containers.

Sugar, sodium nitrate [looks and tastes like salt] olive oil.
Mix these three ingrediants in the right ratio and you have an explosive.

Add a 9v battery, two lengths of wire and penlight bulb with the glass carefully broken, and you have the ignition system.

take yourself, and the little packets with you to the toilet once you're airborne. Mix, shake in a plastic baggie, add detonator circuit. Instant bomb.

Not much boom to it, but slap it against a window and it'll do the job.

Or if you want to use a liquid, vodka and sodium nitrate will do it. You don't even have to carry the alcohol with you, just buy it off the drinks trolly. And hey, it comes with a handy bomb casing, ie the bottle.

[identity profile] ravan.livejournal.com 2006-08-11 08:31 pm (UTC)(link)
In the last screnario, all you need is a little flashight, and a little baggie of sodium nitrate. But it wouldn't make much boom, and would not breach even a window at the join.

The question then comes, since minor amounts of explosives are do-able with common household chemicals, why would the plotters do the elaborate sports' drink can bit? That's what smells the most false to me.

Not really, a lot of people are insufficently creative enough to realise that you can improvise those sorts of bombs.

Sure, someone with a bit of knowledge can look up the chemicals needed to make traditional explosives on the net, or even find some improvised types in things like the anarchists cookbook... but it takes a kinda warped genius to go simple.

Incidently, the IED in question, even down to the use of a gatorade bottle, is a direct copy out of the anarchists handbook. Except back when it was first written, gatorade was sold in glass bottles. They make for a much more powerful bomb. The whole plane plot is direct copy of one tried in 1995 apparently, which would be consitant with the design.

Speaking from experiance, a nitrate/alcohol bomb in a 12oz miniture bottle with the cap screwed on tightly... will blow a tennis-ball sized hole in 1/16" sheet aluminium. That's enough to put hole in a plane, do it in the right place and the hull will just rip apart like paper under aerodynamic stress. A 24oz bomb, is overkill.

What annoys me is how much I've forgotten since I've changed careers out of chemistry. The side effects of a stroke make lab work hard... 8-(

Before the stroke, I had a project to take the Anarchists Cookbook, and pick apart all of the unsafe practices in it. I never got a good start on it.
