No sound very smooth movement flashing different colors then all the same separating then back together

I was a young girl my early teens I was out doors on a hot summer night it was clear.  I can,t remeber who got my attention but when I looked up ther was 6 to 8 lights off a distance like an air plane very close.  I knew then it wasn't normal.  
I called my mother the sound in my voice brought her fast.  At first it looked like air plane lights, but then they separated and changed colors and went  back in formation like the air plane lights but only in that shape 
I am now 67 years old and I have never  since seen any thing like it ....until one night while looking at t.v. the army guy detaitailed the same thing it brought back all my memory like yesterday.  
I haven't shared this with many people but I got to document this before it's too late.  I know what my brothers and mom saw she's no longer with us, but its 3 of us left me being the eldest.  
I am telling the truth and I will stand by it and decided to copy and  sign my name and let the world know what I saw.
