Did they duplicate the supposed terrorist's plans exactly? I'll bet not. They may have mixed up the Tang Bomb but I'll bet they used a commercial blasting cap to set it off. It is a heck of a lot easier to set off a boarderline bang with a real blasting cap to initiate it than to use the very questionable detonator the article describes these tewwowists planning to use.

The video looks rigged for effect. What "destruction" is shown by the video? The bomb was surrounded by loose sheets of plastic looking to be 3 by 6 feet in size, leaning against a short wall. That is a sheet of plywood. Huge area, does not take much to blow one over. A leaf blower or an air gun can blow one over from the distance shown. A large balloon popping might do it.

How about a real test? Complete reality would take an entire scrap aircraft section sealed up and pressurized to high altitude equivalent differential to stress the metal. But at least cut a lav out of a scrap plane and set this same bomb off inside. The structure might contain the blast.

I can blow a sheet of plywood over six feet away with a leaf blower, but a leaf blower inside an airplane lav will do: nothing.
