Bomb-proof lining contains explosion in luggage hold of aircraft

A bomb-proof lining developed by an international team of scientists, including academics from the University of Sheffield, has successfully contained blasts in a series of controlled explosions in the luggage hold of a Boeing 747 and an Airbus 321.

The Fly-Bag, which lines an aircraft's luggage hold with multiple layers of novel fabrics and composites, was tested under increasing explosive charges on disused planes at Cotswolds Airport, near Cirencester, this week.

Using this technology, the tests have demonstrated that a plane's luggage hold may be able to contain the force of an explosion should a device concealed within a passenger's luggage be detonated during a flight. This would mitigate damage to the plane and help keep passengers safe.

After the tests, explosives were placed in the aircraft without the lining to show the damage that could be caused.

Disasters such as the Lockerbie bombing in 1988 drove the need for this kind of invention, as well as the incident in which a printer cartridge bomb was found on-board a cargo plane at East Midlands Airport in 2010.

Fundamental to the design of the bag is a combination of fabrics which have high strength and impact and heat resistance. The fabrics include Aramid, which is used in ballistic body armour.

"Key to the concept is that the lining is flexible and this adds to its resilience when containing the explosive force and any fragments produced," said Dr Andy Tyas, of the Department of Civil and Structural Engineering, who is leading the research at the University of Sheffield.

"This helps to ensure that the Fly-Bag acts as a membrane rather than as a rigid-walled container which might shatter on impact."

"We have extensively tested Fly-Bag prototypes at the University of Sheffield's blast-testing laboratory, but the purpose of these tests was to investigate how the concept works in the confines of a real and the results are extremely promising."

Hardened luggage containers (HULD) have been developed to deal with bombs hidden in passenger luggage, but these containers are heavier and more costly than conventional equivalents.

A European consortium working on the Fly Bag project includes Blastech, a spin out company from the University of Sheffield, as well as partners from Greece, Spain, Italy, Germany, Sweden and the Netherlands.

The technology could either be something that becomes compulsory for all airlines to use if the law was changed or could be used by airlines responding to particular threats.

It has also been adapted for use in cabin holds within the plane if the airline crew spot something they think might be a threat and could be a risk to passengers.

While this may help defend against crude bombs, it is still ridiculously easy to build a more powerful explosive or even a shaped charge to blow right though such measures.

This is a social problem that technology can not easily fix.

The issue has never been terrorism. When one digs well enough, False flags are seen to be at the heart of most terrorism, as the response by ruling systems is detrimental to the given causes, in ways the given cause cannot possibly benefit via. Cui Bono?

The issue has always that these things, the few times they are real....are a response to a motion into clandestinely delivered and violently enforced global oligarchy.

Cows and corporate shills will jump out and claim otherwise, in most cases - helping hold up the cover story for a corporate media.

The story gets a bit more complex than that, but down underneath all the lies and shifts and shell games, that's the greater truth of it.

Cows and controllers and the games played to try and keep it that way.

Oh, you mean back when the Democrats got us involved in Vietnam?
Or was it when the Republicans got civil rights laws enacted?

It was nice of the Republicans to go along with LBJ when he gave America back to The People with Civil Rights laws, opposed by conservatives in both parties.

As far as Vietnam goes, I guess you are ignorant of Dien Bien Phu and our agreement for free elections in Vietnam, reneged on by John foster Dulles?

No, we weren't. And I'm old enough to remember what international aviation was like from the early 1970s on.

Even a perfect foreign policy (whatever that might be) is not going to stop attacks against commercial aviation. Deranged people exist. Cults exist. Ignorance exists. These can all lead to hateful attacks against commercial aviation.

You're starting from a ridiculous assumption that politics alone can solve this dilemma and then you went even further by trying to hang it on one party or point of view. I wish the reality really was like that, but it is not. Posting nonsense suggesting that this might be true just shows the foolishness of this point of view.

We got our Police State after their failure, their Criminal Negligence of 9/11.

Did you fail to notice it was Dubya screaming "WMD!" and "Bring 'em on!"?

Did you notice they were cowering in their Undisclosed Locations when they screamed it?

They sure had you folk figured out, even having the hundreds and hundreds of pages of the draconian Patriot Act ready. How did they know they would "need" it?

You should have listened to us Vietnam War veterans who tried and tried to tell you the truth.
