6 lights in line formation moving northeast from Oneil bridge area over Florence AL6 lights flying in formation coming from Tennessee River from what looked like Oneil bridge heading northeast. Lights were not flashing like normal aircraft and formation started to break up as rear lights seemed to drop as lights in front seemed to rise. Lights looked like possibly helicopters, but have never seen 6 helicopters flying in any formation over Florence, AL, at 10:00 pm....EVER!!!!!! Lights were moving northeast at a faster speed than you would associate with helicopters but were too low to be mistaken for airplanes, not to mention that there is no military base for aircraft anywhere near this area.
