French police loose explosives on jet!

Monday, December 6, 2004 PARIS

Police at Paris' top airport lost track of a passenger's bag in which plastic explosives were placed to test bomb-sniffing dogs, police said Saturday. Warned that the bag may have gotten on any of nearly 90 flights from Charles de Gaulle, authorities searched planes upon arrival in Los Angeles and New York.

For failure modes that are likely to have safety, commercial or environmental consequences, it is a good idea to work at a detailed level.
