I saw this at home in Baltimore, MD. Watching a camera that is used by railroad fans. The fireball descended almost straight down until hidden by trees and a building. A friend captured the fireball and posted it to facebook. He then forwarded it to me via the internet. Here is the facebook URL for the fireball: https://www.facebook.com/Zombiehuner/videos/2246716275357940/
