2008_09_handgren.jpgThe alert about a "suspicious package" at JFK Airport said there were hand grenades in a piece of luggage. The JetBlue terminal was evacuated, only for the grenades to turn out to be World War II grenade replica paperweights. Next time, mail them! JetBlue is having an opening ceremony for its new Terminal 5 today. And yesterday, a Newark Airport terminal was evacuated after many "false positives" on a suspicious bag, which was eventually deemed safe.
