CHICAGO - Chicago's aviation department is launching a test to try to give communities near O'Hare International Airport a break from the noise of jets taking off and landing.
The test that begins this weekend will rotate the runways being used overnight to see if there is a way to better distribute the noise. Residents of communities near the airport have complained about the loud sounds for years.
The test follows another runway rotation test conducted last year and will last 12 weeks.
A third rotation test would likely run from July until October. There will be a survey that will allow residents to give their opinions.
