I was 12 and my friend the same age.
The lights were coming from the West of Dallas, where we lived was on a hill that overlooked the Dallas skyline.
Just as they got above us they stopped.
There was no sound, and I told my friend they were helicopters because my dad worked there.
They were in a triangular formation, the only one in the front an they stopped.
Then they went back to the West, first the lead one then the next 2 then the next 2 an so on.
I never thought about it till I got older.
Now I know better.
I have had others but not as good ever since I have grown up.
I am not a UFO believer but that was real strange.
