The US Army lost control of a radar blimp

It's the runaway llamas all over again... in airborne form. One of the US Army's missile-detecting radar blimps broke off its tether in Maryland, creating havoc both in the skies (the Air Force even sent fighter jets to track it) and among the many, many internet users following its every move. It eventually drifted over Pennsylvania, and there are reports that it knocked out power lines at a school in the state before coming down. We're still waiting to know the blimp's health, but it's safe to say that the Army will be more than a little red-faced as it looks into what went wrong.
