Metrojet A321 crash in Sinai

That's a fly in the ointment. It wouldn't surprise me of the bombers were British citizens fighting for ISIS. What is ISIS anyway? It's not an official country. Its made up of Jihadists around the world, including the US and even more so ---Britain.

Makes you wonder what the Russians will do about it.

 

For the most part, security is just theater. Everywhere.

 

Unfortunately, I think you are correct. However, it gets rid of the amateurs and nut cases and leaves it to the pro's.

 

Just like a home burglar alarm. Hopefully makes them go somewhere else.

 

Bomb in a beer can.

Think I read that it was the equivalent of 2+ pounds of TNT.

Don't know if this is a farce, or that's what they used.

 

Sadto hear it was declared a bomb. Again those poor souls rip.

 

Probably a little of both. Would they really take time photograph the device so carefully? I doubt it. Would they recreate it for pics, though? Sure.

I really doubt that's the bomb. The reason they posted it is to complete the "terror cycle".

It looks so easy to do that people worry so they don't fly. When they don't fly, the economies are hurt which is what the terrorists are trying to do, aside from get people to join them.

It's propaganda. But I believe they will find the actual bomb used just like they did with Lockerbee. That they traced to an exact kind of watch used, the explosive material, and the type of radio it was planted in.

Most likely, this was in someone's luggage. They will find out who's. All the evidence is sitting in the desert. It just needs to be collected and analyzed.

 

IF they had TNT that tin would hold less than half the amount claimed.

 

They are NOT claiming that it was TNT.

It said the "equivalent" of TNT....

It is common to use "pounds of TNT" in the measurement of explosive power, even with Nukes (i.e. "8 kilotons" refers to that weight of TNT).

So the equivalent of 2+ pounds of TNT of plastic explosive, for instance, would fit in a soda can.

 

From what we read, a small enough bomb, placed in the exact right area, and timed to go off at 30,000 feet where even a small breach is catstrophic is what we are looking at. This also implies a higher degree of sophistication and knowledge base compared to just a big bang as the plane gains altitude as in lockerbie.

This is not the JV team.

 

Every year that goes by will increase sophistication. We will never cover all the bases.

It is time (well it was years ago) to just roll back security to a metal detector and pound whoever claims responsibility for these acts when they occur.

There will always be a risk. Always. When someone wants it bad enough, and is even willing to die for it, you just can't defend against it.

Also, give cabin crew emergency override access to the cockpit. Hundreds of passengers are going to fight hijackers so we don't need to risk one person in the cockpit going nuts and killing hundreds a la Germanwings.

 

I don't remember what it is but at 30,000 feet the pressure differential is extreme with the cabin at 4000-5000 feet and the outside way lower at 30,000 feet. The fuselage vessel is a bomb if there is a breach. The breach, however small, is also intensified by the speed. The Comet fuselage failure was over in 6/10ths of a second when the ADF window failed. I imagine that if a small portion of the skin was blown open in the aft lower fuselage of the A320 it would precipitate an instantaneous failure in the structure. Just thinking.

 

The early "unofficial" reports are a bomb placed under a rearward/rearmost? window seat. Likely smuggled on by servicing personnel with airport access while the plane sat on the tarmac for several hours between flights.

The "evidence" is a 1 square meter hole blown through the fuselage with outward peeled skin at that location.

 

It wouldn't take much.

 

Typically the pressure differential at altitude will be around 9 psi.

 

I know that which is why I said "IF they used TNT". I should have been more specific in my post. Even if they used C4 or similar they would not have crammed that much explosive power into that can (which would only contain about 750g). I'm just trying to point out that the ISIS propaganda is just that... it is unlikely to be the bomb used.

 

Thanks for that.


Pics of the wreckage show the tail section separate from the remainder. Apparently the force was enough that when the breach happened, the damage migrated and the entire tail section separated from the fuselege.

 

And hand operated can sealers are readily available, (install tops) they could have had more then one can/bottle with explosives, or even the cart frame, i dont know if they xray drink tray cans and bottle trays from the catering companies prior to loading on the planes...

 

C4, RDX, and other explosives also have a TNT equivalence much higher than 1, usually around 1.5. So a small amount of either could have the TNT equivalence of 2 lbs.

 

A hole of 9 square meters is huge and with a pressure differential of 9 PSI and huge volume going through, it would quickly open the hole larger with an explosive force that would fail the fuselage tail structure.

 

Egypt is protecting their tourist industry. Either way, that's their priority.
