Wife & I driving on hwy I-85 westbound. Sky had multiple cloud formations. My wife held cell phone out window and was snapping shots as we rode. After about 7 shots she stopped. Nothing was viable in sky as we rode. After snapping pics we were looking at them. On the last photo we saw the 4 objects which looked like exhaust coming out of bottom. One or two previous shots showed faint blurred images which I assume we’re part of this 4 but not as close. Never saw items, only appeared in photo. After seeing these my wife and I wondered how we had pics when nothing was visable. Othere who have seen the pic are also wondering how this could be.
