I was on the phone with a friend of mine and i happened to notice a group of about 10 dimly lit lights traveling west in plano, tx. so i decided to take some pictures with my phone, couldnt record because i was on the phone. in total i saw about 15 of these ufo's traveling in the same direction, what looked like some kind of formation and at the same speed. as i kept observing, i saw the lights just slowly dim out and that what it. all 15 lights i observed were gone.
