Silhouette of a climber against the blue sky and the setting sun
A dove flying in the blue sky
The training aircraft went on a flight into the blue sky
British field with beautiful flowers and blue sky
Sandy beach with blue sky
An endless green field under a blue sky
Blue sky over a green plain
Blue sky. White clouds
Frozen tree against the blue sky
Golden grass in a field with a blue sky
The sunflower reaches for the blue sky
Soft, white clouds on a blue sky on a summer day
