Several red balls of light flying in formation over the gulf of mexico with no sound at high speed.

There were a number of red balls of light flying in a sort of formation over the Gulf of Mexico. They were flying low to the Gulf and made no sound. They flew at high speeds and made turns at right angles in such a way that any man made air craft would not be able to do. They appeared and disappeared. They flew back and forth within I'd say a 5 mile length of area.
Witness indicates that date of incident is approximate.  PD
