With the requirement of public ownership thus complied with, events moved swiftly toward the realization of an airport for the Adirondacks. Through persistent effort on the part of various citizens, who maintained close contact with Washington, D.C., the site was inspected and federal expenditures for construction of a Class III airport were approved. Step by step, the Town of Harrietstown Town Board and the Saranac Lake Airport Commission worked closely with state and federal agencies in the building process. Construction of the airfield was completed in 1942. The Town of Harrietstown issued bonds to augment the available funds and erected a terminal building in 1948 and a 100 by hangar in 1950.
