triangle shaped object-3 bright lights-blinked in a pattern-made no sound

My daughters and I were heading home after eating dinner at my mother-in-law's house.  We live in the country, away from the bright lights of the town, so we have a good view of the night sky. 
At first we saw a bright orange light that zoomed across the sky.  We thought it was a shooting star, but then it just stopped in the sky.  Then the light changed to a bright white light and we saw two more lights. They were in a triangular shape and they were blinking in a pattern. We live mear Shaw Air Force Base and we are used to air craft and jets flying over our house. This object did not make any noise. My husband was in his truck behind us and he saw it too.  We saw it for about 30 seconds and then it just disappeared.  It was just so eerie, not only to see, but the feeling that went through my body was just indescribable.  It just sent chills through me.  We did not report it.
