We are truckdrivers. We were delivering to Fairburn, Ga. and just below the airport. It couldn't have been a plane because this object was perfectly spherical but huge. It was fell before I could get my camera out. Traffic was heavy surely others saw it. It fell slower than a shooting star and was blue and yellow with a long trailing blue white tail. The event lasted about 45 sec. and we heard no noise. There was no explosion.
