Jets take off toward the north then orange lights glow in succession repeatedly.While sitting on the balcony of my apartment We saw and heard 2 jets take off from Nellis Air Force Base( less than a mile from my home)The jets shot off towards the north mountain range and were gone. A few seconds later my wife and I were looking to see the jets and saw 2 bright orange circular lights flash on then off, then one on then off slowly, then the other on, then off slowly. We watched to see if we could see what it was and quite a ways to the left saw another orange light, same type, turn on then slowly off, then next to it another on, then slowly off, then again, and one more time, then they were gone. The second time there were 4 in a row. We then saw what appeared to be the jets circling as if the were searching for the lights. Two or three jets appeared to be circling in the distance above the northern mountains of the las vegas valley.
