Helicopter.
Nope, I have seen them many times drunk and blurry eyed with double vision. Unless that spot is right on you it would not look like that consistently like it did. And there is not one other light on a helicopter that bright period. You can’t even see cockpit lights a 1/4 mile away. It was right in the approach path for McCarran airport from first the east and then the west. That is what the other blinking lights were, planes coming for approach to McCarran. I used to live there and know that skyline like the back of my hand.
