It's not the first time that Chicago has had one of these no fly zones enforced. Presidential visits have occassioned the directive in the past.

But what makes this order different is that some nutcase in the OWS movement is likely to challenge it.

A new report reveals plans to keep residents and dignitaries safe during the NATO Summit include a no-fly zone, with a shoot-to-kill mandate for those who break the ban.

As CBS 2's Susanna Song reports, the government is warning small plane pilots that if they enter the no-fly zone during the summit, they may be shot down.

This is no joke. It will be enforced for May 19 to May 21.

The flight advisory was issued by the Federal Aviation Administration. The advisory bans non-commercial aircraft from flying within 10 nautical miles of downtown Chicago and below 18,000 feet.

"The United States Government may use deadly force against the airborne aircraft, if it is determined that the aircraft poses an imminent security threat," the advisory says. "Be advised that noncompliance with the published (notice to airmen) may result in the use of force."

The advisory says lesser violations by airmen might result in civil penalties and the suspension of airmen certificates, as well as criminal charges.

The only aircraft allowed to fly within the restricted area include regularly-scheduled commercial passenger and cargo carriers, police, and military planes supporting the Secret Service.

What better way to expose the oppression of the system and NATO militarism than for some idiot to fly a small plane into the restricted zone and have it shot down? There are at least a dozen small airports dotting the landscape around Chicago so it will be difficult to police them all.

Unless the feds get wind of a specific plot like this, they are not likely to intercept it. No doubt it's thoughts like this that are keeping Mayor Rahm Emanuel - and many residents of Chicago - awake at night.
