City: Black Hawk Helicopter Flights Were Just A Training Exercise

CHICAGO (CBS) -- Yes, those were indeed Black Hawk helicopters that you saw buzzing over downtown Chicago Monday afternoon, but there was nothing to worry about.

The Black Hawk and Little Bird OH-6 helicopters were seen flying down the Chicago River alongside Wacker Drive on Monday afternoon. Many people were alarmed by helicopters and wondered if the city was under attack.

But the Chicago Office of Emergency Management and Communications actually had put out a statement early Monday morning warning people not to get anxious about the helicopters that would be coming later in the day.

The office said the flyaround was part of routine training conducted by military personnel in cities across the country.

The helicopters were seen landing in the McCormick Place parking lot. But the city denies that the helicopter flights had anything to do with the upcoming NATO summit at the convention center next month.
