There is a military airport at Maritsa next to the civil one but it is rarely used appart from some helicopters. Usually military transport planes land at Diagoras.
Two more landing strips on the island, one at Gadoura on the way to Lindos. Nothing to see there but it has a long history, constructed by the Italians in the 30s and used by the famous Italian SM79 torpedo planes during WWII. The last in at kattavia in the far southwestern part of the island and it is used by the military during manouevers (i had landed there once in a HAF C-130).
