We observed two red lights moving at incredible speeds in perfect formation over Charlotte.

During an evening walk, my son and I noticed two reddish bright lights in the sky south of us.  The lights were moving faster than any plane but about the same altitude as a jet. The distance between the lights was possibly a mile or more but moved in perfect synchrony. They moved in a north easterly direction for about 30 30-45 seconds then disappeared.  About 15-20 seconds later the lights reappeared due east of us for a moment then disappeared again.  No aircraft I've ever heard of could move that distance so quickly.
