Three completely silent red lights traveling in the sky which had the ability to alter configuration.

I was enjoying the clear night sky, when I noticed 3 lights (light red in color) traveling in concert with one another in a straight line.  It was night so I could not make out a shape, but it did appear that there was some sort of drag effect occurring behind each light, almost like blurring of the atmosphere.  Given the relative distance from me, I would have heard an engine noise if it were a plane but it was completely silent, also the speed was much faster than any plane I’ve seen.  
About half way through the occurance the lights changed from a linear formation and configured into a triangle.  The object(s) were heading from southeast to northwest.  
I am 30 years old, in good mental and physical health, have a doctorate and MBA and I am not known to fabricate or exaggerate stories.  I was honestly very startled by this event and have no explanation for what I saw.
