A very long string of white lights appearing to be of the same enormous object configured in a line traveling silently at a high speed.

Very visible long straight line of white lights, not blinking but constant, very close together appearing to be originating from the same craft.  Craft was moving from NW to SE at a rapid rate but gave no sound at all. Craft appeared to be high in the sky, approximately 7000 ft.  Was not low, which adds to the enormous size of the craft.  Craft faded out very high in the sky after passing over, which again proves it was enormous and not an optical illusion. Craft flew at a constant speed.  Could not see a defined shape of the craft, only the lights. Took photo with camera on phone.
