I went up to our local community turbine this morning to read the meter. The sun was out, albeit very low in the sky, and it was very cold. The turbine was making a reassuring swishing sound, but inside the tower there was a pentrating whistle.
So I got out as soon as I could and flew my little Spark drone to get an overhead shot of the turbine. I already had the permission of the farmer who owns the land.
It was very difficult to see the picture on my iPhone because of the sun, but I managed to capture a few shots and this is one.
