The V formation greatly boosts the efficiency and range of flying birds, particularly over long migratory routes. All the birds except the first fly in the upwash from the wingtip vortices of the bird ahead. The upwash assists each bird in supporting its own weight in flight, in the same way a glider can climb or maintain height indefinitely in rising air. In a V formation of 25 members, each bird can achieve a reduction of induced drag by up to 65% and as a result increase their range by 71%. The birds flying at the tips and at the front are rotated in a timely cyclical fashion to spread flight fatigue equally among the flock members. The formation also makes communication easier and allows the birds to maintain visual contact with each other. (Souce: http://en.wikipedia.org/wiki/V_formation)
If we consider that light is made out of a formation of multiple particles that generate a draft than we can consider that it would use a V-formation like the birds because it is the most economic formula to cross large distances.
If we consider that the group would be traveling through Aether where there is nog gravitational influence, than we might consider that the formation is no longer necessarily flat, and that it has a spiraling forward motion where it has break through matter in 3 directions; straight forward along the Z-axis (green), and Up & down along the vertical Y-axis (red, blue). The (8) has at all these 'groundbreaking' cornerstones a V-shape. The whole formation is closed in the back with a 'V' in the opposite direction (yellow), constructing a perfectly symmetrical and fluent circuit where-in all the parts can automatically change position to preserve energy just like the birds do.
