This weekend marks the 10th anniversary of the destruction of Meigs Field.
Working under cover of night, bulldozers, escorted by Chicago police, dug trenches across the field and cut access to airstrips.
Media were kept away until the mission was completed.
Mayor Daley, at the time, claimed he destroyed the airport for security reasons. It was the post 9/11 era and he wanted to turn the 91 acres into a nature preserve and recreational venue.
But 10 years later, some critics say, Northerly Island is a long way from the vision Daley promised.
