The department is authorized on behalf of and in the name of the state, out of appropriations and other moneys made available for such purposes, to plan, establish, construct, enlarge, improve, maintain, equip, operate, regulate, protect, and police airports, air navigation facilities, and air markers and/or air marking systems, either within or without the state, including the construction, installation, equipment, maintenance, and operation at the airports of buildings and other facilities for the servicing of aircraft or for the comfort and accommodation of air travelers. For such purposes the department may by purchase, gift, devise, lease, condemnation, or otherwise, acquire property, real or personal, or any interest therein, including easements or land outside the boundaries of an airport or airport site, as are necessary to permit safe and efficient operation of the airports or to permit the removal, elimination, marking, or lighting of obstructions or airport hazards, or to prevent the establishment of airport hazards. In like manner the department may acquire existing airports and air navigation facilities. However, it shall not acquire or take over any airport or air navigation facility owned or controlled by a municipality of this or any other state without the consent of the municipality. The department may by sale, lease, or otherwise, dispose of any property, airport, air navigation facility, or portion thereof or interest therein. The disposal by sale, lease, or otherwise shall be in accordance with the laws of this state governing the disposition of other property of the state, except that in the case of disposals to any municipality or state government or the United States for aeronautical purposes incident thereto, the sale, lease, or other disposal may be effected in such manner and upon such terms as the department deems in the best interest of the state. The department may exercise any powers granted by this section jointly with any municipalities, agencies, or departments of the state government, with other states or their municipalities, or with the United States.
