Should the governing body of any city which has been requested by the United States to furnish the site for an aircraft control and warning station and the federal authorities deem it best to condemn the needed land in the name of the United States of America under the power of eminent domain vested in the federal government, then such city is authorized to pay any awards made to the owners of such property so taken for use as an aircraft control and warning station and all court costs incurred in connection with the condemnation proceedings to the same extent that they could pay such costs if the condemnation had been filed in the name of the city.
