Fly Me To The Moon

An all blue sky today. The only clouds are the contrails of the plains.
Contrails, or condensation trails, are formed as a plume of carbon black and exhaust of airplanes comes into contact with the cold air in the upper atmosphere, whereby ice particles are formed. Later these stripes lose their linear character and become cirrus clouds.
The plume needs to cool down first, before it can condensate. Here you can see that there is a gap between the engine exhaust and the beginning of the contrail.
