I would guess that the contrail was formed some time before that photo was taken HIDDY, they can dissipate quickly at times but for the Cirrus to have formed in the way it did here, it was likely more stable up there and formed a ribbon of cloud when the plane passed overhead between an hour and 3 hours before this picture...then the winds started to shear (possibly with the strengthening of the Sun if this picture was about 9 AM or so) and blew through the ribbon of cloud from the right side causing the lines we see.
