No planes and no helicopers, nothing moving that wasn't natural. Not even a cloud - just blue from zenith to horizon. Blue from dawn to dusk.
Except I suppose there was something in the sky, something that gave the horizon a hazy look, a something that gave the sunsets that golden glow of yesterday's photo.
The volcanic something that has my brother and family stuck on their holiday in Egypt.
Volcanic ash covering Europe from Ireland to Russia, floating up there in the blue.
