Contrail Saltaire - @juliank @photocontest

in bluehourphotography •  6 years ago 

On perfect early summers day, two aircraft crossed paths leaving a temporary condensation trail, or contrail in their wake.

There are of course many conspiracy theories surrounding contrails but basically, they are nothing more than water vapour and ice crystals, formed when the hot exhaust gasses from a jet engine condense in wet, cold air.

So why do some go a long time, and others simply quickly fade ?

Go here for an excellent and simple explanation

Of course, the Scots might have sent up these planes and be trying to tell us something.........

Great timing...

I've always liked to lie on the grass to see the wake that planes leave in the sky

me too, but then it makes me long to be back up in the sky :-)

how charming the sky
