Flying against air traffic norms in the area .

This is an area of NYC where plane routes are generally from south to north and its very busy with plane traffic since there are 3 major airports in the area. I was pumping gas at a station and for some reason I looked West and witnessed a fireball traveling from west to east not too fast. I said to a man pumping gas next to me and asked him "Do you see that". He answered yes and stated  " We need all the help we can at this point" It definitely was not fireworks or a flare. because it kept the same steady trajectory until it was out of sight. It made no noise.
