We had the chance to have a trip to Icelandn which is really aother country ! I had the opportunity to see gliders of two types over there.
First the "natural ones", particularly Fulmar which are soaring really well over cliffs :
And then the "imported ones", seen at
Sandskeid airfield near Reykjavik (BISS)
According to local pilots, you can as well fly thermals, wave or slope (as on this day). The nice thing is that in summer you can fly at 11PM...
Sadly I had not the time to fly as proposed by the people there.
