My sister reported this incident when driving north from Gambrills Maryland towards Baltimore: It looked like a plane on fire. It was a ball of fire with a trail of black smoke. It was falling straight down. It was small, as though the object was far away, and not at our BWI airport. As it fell closer to the ground the flame seemed to go out and we didn't see any explosion or more smoke. <br /><br />Anyone hear or see this incident?
