The explosive was discovered two days later, Wednesday, during a routine maintenance check. Especially the parents were concerned because the school bus was then used to transport 26 students from two elementary schools and one high school over the two days the material was left in the bus. CIA was quick to assure everyone that the stuff “did not pose a danger to passengers on the bus” and needed a special detonator to work.. The Agency coordinated closely with local authorities and recovered the training material. “The CIA really expressed its deep concern and regret today, and it was sincere,” Loudoun schools spokesman Wayde Byard told to the media. Training exercises among groups in this program were suspended. Some acid comments targeting CIA’s error appeared in the media.
