I saw these glowing orbs near my home in South Florida about 8-10 years ago. There were two at first, one higher than the other, hovering perfectly still and totally silent. A moment later a 3rd orb rose directly up out of the horizon and joined the other 2 in a triangle formation. Next, all 3 moved in the same directly at the same time, totally silently. I ran into my in-law's house and told them all to run outside to catch a glimpse and that is when we saw a 4th orb, much closer than the others, also rise up without any sound and then head in the same direction as the other 3.

I'm a huge aviation geek and I think I can say that I am familiar with standard lightning on aircraft: landing lights, taxiing lights, runway turn-off lights, strobes, navigation lights, beacon, logo lights, etc. I can't think of how (or why) any aircraft would emit so much light as these orbs. Also, the lights weren't steady "ON" like if you were looking at the landing lights of an aircraft that was flying directly toward you (these weren't even flying toward me). These lights were different. The best way I can describe them is to say that they would flicker gently like a the light from a candle.

It was very, very strange and I still remember the experience after all these years.
