I was driving when i saw blue lights that looked like an airplane landing. As i got closer i could see how close to the ground they were, just above the tree line.one pair of lights did a complete u-turn, and started to ascend and thats when i noticed a second smaller pair of lights follow on the same exact path. ,At this point, Ii had no idea what i was looking at and as i realized this is nothing ive seen, they were about 2 miles away, went over a further away higher elevation tree line and back down and completely out of sight
