4 bright-red lights took off seemingly from the ground in the southern sky. They all, in line, went straight up a small distance, then began to fly East, while gaining some altitude, in a line. Very suddenly, the lead Red changed it's color to a yellow-white, and began to slowly descend. The remaining Reds, one by one, began to disappear while flying north-east. The remaining (now yellow-white) light drifted back west to near where it originally appeared, then rose in the sky and stayed static for at least 30 minutes. In that time, another Red light appeared on the horizon, went skyward until it was over the original light, then disappeared. As of this writing, the original light is still in the sky exactly where it was with no movement, and no other lights have appeared or moved.
