A man boarded an American Airlines flight in Barbados with a loaded gun and flew to Miami with it in the cabin. The Transportation Security Administration (TSA) launched an investigation into the security lapse, which aviation experts said could have caused a disaster. The TSA informed the authorities in Barbados of the incident. The Department of Homeland Security relies on foreign governments to maintain aviation security standards at last-point-of-departure airports with direct commercial flights to the US. Security officials said Latin America and the Caribbean are at risk of being launching points for terrorists targeting the US.
