Tallahassee Sighting

I went out to smoke a cigarette when I saw 2 lights moving in the sky to the southeast of Tallahassee. I paid more attention when I saw them fly horizontally and go vertical, one chasing the other.  They were moving so fast I thought they were spot lights or my imagination. 
I went back in my work and came back out 15 min later for another smoke and to leave when I looked over and the 2 lights were still chasing each other but where a lot closer.  I stood there and I saw 2 bright spheres flying at really high speeds all over the sky.  This continued for another 15 min when they started to slow down.  
I wasn’t going to report this until I saw 5 more spheres appear, like they where there the whole time but didn’t have lights on.  Six formed a V formation and one was to the north of the V but behind the leader of the V.  They flew off at extremely high speeds to the northeast until I couldn’t see them anymore.  The date and time of the sighting was 04/26/10 at 23:45 to 04/27/10 at 0:15.
