2 lines of green, constant lights

I went outside for a cigarette around 2005 and looked up at sky like I always do. I saw 2 lines of green lights moving fast across the sky from west to east. At first I thought it might have been a meteor with a tale but I saw it was dozens of individual lights, green & constant. Staggered in random groups from 1 to 3 in a row, then space, then another group. Both lines different in groupings and spacing, reminding me of piano player tape. The line of lights moved very fast & w/o sound. As the got farther east they began disappearing from the beginning of lines to end but all at one spot in sky. Seemed like they were entering a tunnel or turning off lights when reaching a certain spot. Sky was clear & lights were much brighter than stars in sky.
