6 objects flying north near area 51i live in las vegas nv and was visiting rachel nevada which is about about three miles from groom lake(area 51). as i was looking at the night sky, i noticed 6 objects flying in a v formation at about 22:55. They were moving rather slow,(like a single engine prop plane) but seemed to change direction in an unpatterned way. all 6 always stayed in perfect formation. they were heading north, and disappeared 3 minutes later over the horizon.i never saw hem land or take off. i did notice however, three f-16 fighter jets chasing them a few minutes later
