"SAN ANDREAS, CA (AP) - 12 are dead and 23 injured after an American Airlines 767 fired on a Boy Scout model rocketry event. The jet, which had taken off from San Francisco minutes before, apparently detected and responded to what it classified as multiple launch threats. This follows up last week's massacre at the Jamaica, NY KOA campgrounds when a barbecue triggered defensive missile firing from another Boeing aircraft."
