We were on top of the stadium working at the super bowl when i spotted three or four orbs above the clouds moving west to east. my co-workers looked up and we noticed there were much more and they were all moving in the same direction. the light they admitted was constant but because of the clouds that look like it was flickering a bit. some were further behind the others and they appear to be moving much faster. the altitude that they were at coupled with how quickly they move across the sky i would say they were traveling at a rate of speed that common aircraft cannot do.
