We were at a camp ground near PA/OH border. Large Cell was coming in about hour before sun set. it was massive storm so we were watching it form our camper. Then my sister mother and I all saw the same thing a shiny object moving fast along the Horizon parallel with the lake, we all ran down to the water front to get a better view and the first object abruptly shot up at a 45deg angle (i though a wow water are we witnessing) we all stared in amazement. The first one as fast as it went up came back down to hovering above the lake surface and a second one appeared out of nowhere (possibly from under water)? They both kept moving West and then vanished.
