Erslanda was an airport in Ersmark north of Skellefteå that has been disused for many years. It was in operation between 1959-1984 and was the base for Skellefteå Gummifabrik's (Skega) aircraft. They have had both a Klemm and a Piper PA-30 as corporate aircraft.
This is a basic recreation and utilizes models from libraries. I have had a hard time to find any reference pictures but I know they had a small tower and the approximate sizes of the buildings.
In the real world, the airport had the code ESNE, but as this has since been used by Överkalix, I changed it to ESN5.
