I'm glad you posted that link. There is not one single process or procedure in place by the TSA today that would prevent the very same attack from occuring if it were attempted. If you think the TSA could detect and stop it, you're being delusional.

There are no x-ray devices that will detect nitroglycerin - you're only hope is a random swab, which would be negative if the chemicals are packed and sealed in containers of 4oz or less.

Each mule can pack about 4 x 4oz containers of nitro in their 'Kippie Bag', and once airside, convene to transfer the smaller amounts into larger containers to be brought on board for detonation.

So exactly how would the TSA stop or detect such a plot? Please do tell.
