WATERLOO, Iowa (AP) – The Waterloo City Council has voted to close the shortest of the local airport’s three runways — a proposal that had drawn opposition from some pilots. The Waterloo-Cedar Falls Courier reported that the council voted Monday for the airport director to work with federal authorities on the decommissioning. The director had recommended closing the runway because of safety and liability concerns. Several pilots told the council at an earlier meeting that the runway is a safe alternative when high winds and other issues make it harder to access the two primary runways.
