explosively pager
The Secret Service managed an incredible logistical operation. Inserting xy g PETN into thousands of pagers. A pager is a relatively small device,
usually smaller than a cell phone. And as you know, there is very little room for any changes in any electronic device. I estimate that the HE took
90% of the battery compartment. An integral part of the charge is the detonator, the size I estimate on 10 x 4 mm. Without metal tube. The advantage
of a modern Li-Po battery is that
that it is vacuum sealed. PETN inside is therefore difficult to detect as an odor trace. Furthermore, 95% of the battery's weight consists of copper
and aluminum. Which makes it difficult to detect the different design by X-ray. So the battery is an ideal place to put the HE. But even so, at least
10% of the battery capacity had to be left for the pager. Even before publishing detailed information, I estimated the amount of HE used to be at
least 15 grams.
Some reports state 3 grams of HE, other sources 20g of HE. According to estimates, the size of the pager is approximately 100 x 60 x 30 mm. Which is
enough room for at least 10g of HE. Hole in metal table looks on at least 10g HE, measured by secondary hole in wooden table under. But rather 15 -
20g HE is more realistic.

yes, very clever infiltration. Apparently there was a second round of explosions, this time walkie-talkies. I have seen some speculators saying the
PETN was set off by thermal shock from battery overheating, and that some owners noticed their pagers get hot and discarded them. Seems unlikely to me
compared to a cap. But impressive that no devices exploded prematurely if they were bought 5 months ago, especially if they did contain a blasting
cap.
I hope I'm allowed to say this here. I think this was not a targeted military attack, but a terrorist attack on civilians. If you put explosives in a
phone, you can get the guy on a phone call, confirming his identity via voice and holding the explosive to his head. But there's a picture of a phone
store with lots of smoke, I think these pagers were sold on the market. If you put explosives in consumer devices (that may often be bought by
Hezbollah) and explode them without regard for device position or user identity, you are going to get explosions killing civilian owners, shrapnel
injuries in supermarkets, little girls killed bringing their father's pager to him, etc. Which is what has been reported. I think about Life After
Detonation and then of these 2800 injuries...

The fact that none of these devices were discovered, even by airport security, is extremely concerning.

There were claims made on social media about how nobody uses pagers and therefore it was such a clever attack because only Hizbullah members would
have a pager. I found this particularly unconvincing, because I had carried a pager for work at my last job -- it was the accepted alternative to
installing some kind of spying software on my cell phone. Apparently this is also true at some hospitals in Lebanon, where, according to The
Economist:
| Quote: | | Medics at the American University of Beirut’s hospital were told to throw away their own pagers. |
Luckily, our pagers used non-rechargeable AA batteries, and I don't live anywhere near Lebanon.

Am thinking exactly the same thing. If they really knew "terrorist" would get these device, why not keep them online to track them and listen what
they say.

It's a horrific and barbaric attack.
| Quote: | US and Lebanese sources told the New York Times and Reuters that Israel had planted small amounts of explosives inside the pagers which blew up on
Tuesday.
An ophthalmologist at one hospital in Beirut told the BBC that at least 60% of the people he had seen had lost at least one eye, with most also losing
a hand.
“Probably this is the worst day of my life as a physician. I believe the number of casualties and the type of damage that has been done is
humongous," Dr Elias Warrak said.
"Unfortunately, we were not able to save a lot of eyes, and unfortunately the damage is not limited to the eyes - some of them have damage in the
brain in addition to any facial damage.” |

I have found PETN to be quite efficient in small masses. RDX appears to be even more efficient in micro application despite the common belief that
PETN is lower critical diameter.
While I do l appreciate the novel use and micro application of explosives generally, In this instance the application is so indiscriminate it is
degenerate and unprofessional in a military context. It is a group of people, on behalf of a nation state, detonating explosives in public areas in
proximity to definite civilians, and the targets are only theoretically military targets, not positively identified military targets. It isn't
possible to ascertain the location and identity of all the people in possession of so many devices at one time. Not to mention the greatly multiplied
number of civilian injuries. So it is indiscriminate bombing and killing of non-uniformed combatants in a civil environment with no regard for
civilians at best. Terrorism at worst.
Furthermore, I noticed (conspicuously) that the topic, it's technical explanation of "batteries", and the popularity of the topic were all produced
and served to the public by a wide array of news media outlets and social media hubs simultaneously, in a manner that demonstrated an oddly intensive
interest to the media, disproportionate to the event, on a topic that is frankly no more interesting or noteworthy than the explosions of plants in
Russia taking place at the same time. One of which registered on the international richter scale.
I would assume from these observations, that the intensity of reporting on the topic is propaganda to make israel appear competent. The technical
details are untrustworthy, because the true methods would be concealed. The explosive application isn't as incredible as the fact that so many people
had devices within a supposed combatant network. If this is the case, then it's likely that next, all of hezbolla will start having their matching
athletic sneakers detonate. If you can get that many devices into the hands of a network of non-uniformed combatants, then they aren't very
intelligent, and have no security protocols for their incoming equipment and distribution.
In my opinion, it is more likely that hezbolla at it's funding source, is actually an israeli organization, and that is the reason that so many
devices could be distributed. Regardless, it is a radical departure from traditional warfare and is certainly outside the bounds of what is considered
ethical. I don't see any ethical difference between this sort of application and say, suicide bombing. Both are directed at political/military targets
generally, both indiscriminately kill and injure non combatants. They are the same. They are both terrorism.
The difference is that one of the methods requires a large network and lots of funding, and nation state hosting, and the other only requires one or
two people to accomplish independently. Suicide bombers can be radicalized individuals, independent from their respective states, for them to act
doesnt hold their states culpable. This incident demonstrates that the israeli nation state itself is radicalized at the same level of terrorists but
with access to NATO equipment and resources.

The primary hole next to the mirror is cca 40 x 40 mm. And the secondary hole next to the hair brush is about 80x80mm in diameter. Of course, they
were right under each other at the time of the explosion. The bottom plate, about 20 mm thick, was pulled out later for the photo. The top plate has a
metal surface, I guess aluminum with a thickness of 1 mm. The edges at the top hole are not sharp, indicating a blast charge distance of approximately
5 - 10 mm. Which corresponds to the distance, i.e. the thickness of the plastic material of the pager. Given these clues, I estimate the weight of
pressed PETN to be 7 - 10 grams. The stated 3g of PETN is too little for secondary punching of the second plate....

Interesting observation. I saw some video of a pager detonation which appeared to only be a few gram payload, difficult to accurately measure, but it
may be up to 10 g, but it seemed perhaps half of that to my eye. There were some other detonation videos I saw that were obviously in the 30+ g range.

The frightening thing is though, that microdetonators nowadays exist to be small enough to even fit in wireless earbuds that are far more common in
the west than pagers. And those detonators, containing maybe even a few 100 milligrams of EM, could be wirelessly initiated via RF or high frequency
from something like a smartphone nearby. A blown eardrum would be the least of my worries then. And to think that these pagers were built by a country
directly funded by US taxpayer dollars…

Probably secret services have listened to those devices for God knows how long!
And they might have already figured out the connections and where the HVTs (high value targets) are located! in the event of the clash; they just
needed to cut off the communication lines and take their enemies by surprise!

During my childhood, there were myths circulating, one of which suggested that modern technology allows for the concealment of explosives within a
coin that could be remotely detonated. From a scientific perspective, can this claim be substantiated?

No need to prove scientifically. Young men in Beirut have pockets full of such coins......

The main problem I see is density. Metals used in currency are at least 1.4 times as dense as, say, HMX or TATB. It is hard to explain a half-dollar
coin (11.34 g copper/copper-nickel alloy, density about 7.16 g/cm3) that weighs just 3.5 grams (2.7 grams TATB, density about 1.9
g/cm3; 0.8 grams for detonator and outer layer), for example.
I'm glad my ancestors went West rather than East.
