Yep, I bet the Terrorists wanted a 1-2 punch.
Knock Americans off balance with the first strike, hit em again for the knock-out blow a short while later. Trust me, the US economy and its people are on a razors edge right now.
A tanking stock market, massive layoffs, key parts of the economy failing, all when we started to see an up-swing.
If they can get off even one terrorist attack, especially against an airline, it will be catastrophic.
This plan they had hatched was detailed, well funded, and thorough. It can still be devastating. Just pray the FBI and CIA are now up to the task of finishing the round up.
My best guess is that the Terrorists would go after other means of transportation. Probably hit a train line, or blow some critical bridge. They have already shown how vulnerable our Airlines are, and they would profit most from showing how our entire infrastructure could be affected. Or they could target our power grid.
A nation is only as strong as its infrastructure. Bring that infrastructure down, and you can bring a nation down. Its how our Airforce targeted Iraq and Serbia. And its our greatest weakness.
Here's hoping I am wrong.
