Mauterndorf LOSM it is. The football pitch postdates the Google image. The railway line is narrow guage and runs steam trains and hauls timber in the summer. The airfield is the highest in Austria at 1110m amsl (for our continental friends). Well known gliding site due to mountain wave and ridge soaring conditions. Powered aircraft welcome in the summer. I understand that a few ski equipped aircraft operate in the winter. Friendly lot there.
SLB has control.
