Colorado Springs - The commander of military forces protecting North America has ordered a review of the costly air defenses intended to prevent another Sept. 11-style terrorism attack, an assessment aimed at determining whether the commitment of jet fighters, other aircraft and crews remains justified.
Senior officers involved in the effort say the assessment is to gauge the likelihood that terrorists may succeed in hijacking an airliner or flying their own smaller craft into the United States or Canada. The study is focused on circumstances in which the attack would be aimed not at a public building or landmark but instead at a power plant or a critical link in the nation's financial network, like a major electrical grid or a computer network hub.
The review, to be completed next spring, is expected to be the military's most thorough reassessment of the threat of a terrorism attack by air since Al Qaeda's strikes on Sept. 11, 2001, transformed a Defense Department focused on fighting other militaries and led to the Bush administration's "global war on terror."
