The Poplar Bluff Municipal Airport is located on approximately 344 acres, 4 miles east of Poplar Bluff, on a level tract adjacent to State Highway "B" (old U. S. Highway 60) in Butler County. It was constructed in 1934 and originally named Earl Fields Airport as a memorial to the late Alderman Earl Fields, who was also Chairman of the Airport Committee. The name was changed in December, 1950, to Earl Fields Memorial Airport dedicating the Airport as a memorial to those who died while serving as members of the armed forces of the United States in World Wars I and II. In 1970, the name was changed to the Poplar Bluff Municipal Airport and was dedicated to the memory of Earl Fields.
