Desperate Haitians have spent a third night in the streets of the capital, Port-au-Prince, waiting for promised aid that is slowly trickling in following Tuesday's devastating earthquake. The aircraft carrier USS Carl Vinson was expected to drop anchor off the Haiti coast Friday where it will serve as a floating airport for helicopters carrying rescue teams and supplies. Troops and planeloads of desperately needed food and medicine from many countries began slowly arriving in Haiti Thursday after the worst earthquake in 200 years reduced the capital city to rubble. The aid flights, however, have swamped the main airport.
