Nice shot, and very unusual.
But not actually inexplicable in terms of normal atmospherics.
Your photo has all teh characteristics of an aerodynamic contrail coming from the top of hte a/c's wings.
the physics is pretty simple - the top of the wing is a low pressure area, so as the air pressure decreases across it the temperature decreases -
that's your basic gas law.
As the temperature and pressure decrease the ability fo the air to hold poisture also decreases, and if conditions are right some moisture will
A fuller explaination and some links and photos can be seen here
So to me it has all the characteristics of a known phenomena.
How can you tell it is a chemtrail and not anything else?
