Airport security officers around the nation have been alerted by federal officials to look out for terrorists practicing to carry explosive components onto aircraft, based on four curious seizures at airports since last September.
The unclassified alert was distributed on July 20 by the Transportation Security Administration to federal air marshals, its own transportation security officers and other law enforcement agencies.
The four seizures were described this way:
San Diego, July 7. A U.S. person — either a citizen or a foreigner legally here — checked baggage containing two ice packs covered in duct tape. The ice packs had clay inside them rather than the normal blue gel.
Milwaukee, June 4. A U.S. person’s carryon baggage contained wire coil wrapped around a possible initiator, an electrical switch, batteries, three tubes and two blocks of cheese. The bulletin said block cheese has a consistency similar to some explosives.
Houston, Nov. 8, 2006. A U.S. person’s checked baggage contained a plastic bag with a 9-volt battery, wires, a block of brown clay-like minerals and pipes.
Baltimore, Sept. 16, 2006. A couple’s checked baggage contained a plastic bag with a block of processed cheese taped to another plastic bag holding a cellular phone charger.
Yes. they did thwart an attack very similar to this before. But this was the whole scare over liquids. Remember? No liquids allowed over 3.5 ounces?

It seems that while we were looking at liquids they were seeing if they could get plastique n board!
Nitroglycerin is made of carbon, nitrogen, hydrogen and oxygen. A physical shock can start a chain reaction that breaks its molecules down into carbon dioxide, water and oxygen. The breaking of the bonds between the atoms releases an enormous amount of energy in a very short amount of time.
Nitroglycerin is a component in some relatively stable solid explosives, like dynamite. But as a liquid, it's extremely dangerous and volatile. You typically have to use a blasting cap to detonate a stick of dynamite, but you can accidentally trigger a nitroglycerin explosion with a physical shock. It doesn't blow up at the slightest movement as depicted in some movies and TV shows, but you can detonate it by hitting it.
Nitroglycerin is oily and clear, so if you poured some into an opaque lotion bottle, no one but you would know what was really inside. However, nitroglycerin's inherent instability would make this bottle very dangerous for you to carry around.
Like nitroglycerin, most liquid explosives are made of unstable molecules. These complex molecules break down into ordinary, stable molecules when exposed to the right stimulus. Even a very minor shock can start the process, and since it involves the breaking of atomic bonds, it releases enormous amounts of energy.
The terrorists most likely intended to remove the explosives from their carry-on luggage and detonate them while the planes were over the Atlantic Ocean. They may have planned to use explosives that require the mixing of two different liquids in order to start the reaction. Unnamed sources have stated that the attackers planned to mix a liquid dyed to resemble a sports drink with a peroxide gel to create an explosive substance.
According to other sources, the attackers intended to use triacetone triperoxide, which can be made from readily available substances like hydrogen peroxide, acetone and acid. Like nitroglycerin, triacetone triperoxide molecules are made of hydrogen, oxygen and carbon. When it explodes, it breaks down into large amounts of ozone and acetone.
Regardless of which exact substance the attackers planned to use, the liquid nature of the explosives would have been central to the plot for two reasons:
Liquid explosives are very volatile, so the attackers would not necessarily need elaborate or powerful detonators to start the explosion. Without as much material to smuggle on board, the attackers would be less likely to attract the attention of airport security. In the case of the August 2006 plot, unnamed officials speculated that the attackers planned to use cell phones or MP3 players as detonators.
Smuggling a liquid onto an airplane would not be very difficult. The attackers may have planned to use ordinary bottles made for hair gel, shampoo, lotion or other liquids and gels. Under typical circumstances, airport security probably would not question items like these.

These are indeed trying times, and to look at the world today with rose colored glasses donned to your eyes is a sore mistake. I'm not an alarmist. I would do anything - ANYTHING - to insure that the world would be hate and war free. Unfortunately, that's not the case. This new breed of "terrorist" is smart, clever, and extremely patient.

It is obvious you are much more well versed than I on such matters.
Thanks for a mature and rational response. That is refreshing on this board. I look forward to further exchanges.
Thank Sir.....kk

But local TSA Security Director Michael J. Aguilar – and the chief of the police agency that patrols the airport – said Wednesday that while screeners initially thought the packs held a clay-like substance, it was quickly determined they contained the usual blue gel.

Not to be argumentative, but to further my point. I had remembered the following excersice and just found the link.
First, simply watch the video and count how many times the people in white shirts pass the ball. That is all you must do.
Don't cheat.

I am sure the most astute here will see what others don't. My point is simply that the act of diversion is powerful.
