The Insular Airfield is an airport situated on an island of the coast of the continent the main KSC is on, and is a prime first target for beginner spaceplane pilots. It is comprised of a landing strip, hangars and a tower located on the largest of the string of islands 31 km east of the KSC. The surface of the landing strip is sand and is on an elevated area making it hazardous to overshoot and falling off the strip or turning at an end. Prior to the redesign in version 0.22 the landing strip had a grass-like texture, which made it harder to find from the air.
With 0.22 the buildings are now south of the strip instead of north. The tower looks ruinous with segments of the façade fallen down and ivy growing inside the building. It is still possible to get to the top with a Kerbal via an external staircase at the north side of the tower.
The landing strip is not illuminated. There is only one light on top of the tower.
