Not terrorism, apparently

I felt paranoid wondering if there was any chance of sabotage or other hostile actions, but I realize now that I was far from the only person to have this thought, and I flipped to Peter Jennings saying that this has effectively been ruled out, or at least that the accident happened too far up in the atmosphere for there to be any chance that a missile or other projectile could have impacted the craft, and that the numerous photos and videotape of the incident show no such outside interference.
