A Partisan airport was located near Otok during World War II. The building of the simple grass runway began in spring 1944. The airport was ready for operation in June. Its military code name was EKG 2 and the commander was Stane Oberstal. The first aircraft landed there in September the same year. The airport was used by Allied airforces in order to deliver humanitarian and military aid, and to evacuate wounded and other people. It was used by Soviet aircraft until the end of 1944 and by British and American aircraft until March 1945.[4] The airport was part of three other Partisan airports in the vicinity: Krasinec, Griblje, and Prilozje after the first airport Podlesk ceased operation in September 1944. Today an original DC-3 airplane on the fields near Otok serves as a memorial for the airport and the Allied help.
