2 orange fireballs flying parallel to each other then progressively fading out.

My husband and I were driving when we noticed what looked like 2 orange fireballs in the sky. I did not see them first appear, but just happened to look up and saw them. We stopped the car and got out to get a better look. They were flying west toward Cecil Field, parallel to each other/ side-by-side, at the same rate of speed. They appeared to be flickering slowly, getting dim and then bright again, but they were also going up and down slightly, almost like the were floating or bouncing on the wind... like they were dancing. Then the one to my right dimmed and went out completely. After maybe 15 more seconds the other dimmed and went out. Since it was late at night and the sky was dark I could not tell if there were any objects in the sky after their lights went out. They were not aircraft, because there were no other lights or even a craft seen. There was also no sound. They did not behave like flares or skydivers with flares. They were not falling, but flying straight ahead, keeping the same altitude and same rate of speed.
