US Aircraft to Deliver Medical Support to Chile VOA News 09 March 2010 A doctor examines a boy on a provisional house in Constitución, Chile, 9 Mar 2010 Photo: ASSOCIATED PRESS A doctor examines a boy on a provisional house in Constitución, Chile, 9 Mar 2010 U.S. military aircraft carrying medical supplies and personnel are to arrive in Chile Tuesday to help victims of the massive earthquake that struck February 27. In a statement Tuesday, the U.S. Southern Command said three C-17 Globemaster aircraft were en route to Chile with a team of 84 airmen, including 63 medical personnel. The team is designed to provide a variety of medical services including surgery, radiology, pharmaceutical, dentistry and laboratory work. The statement said the Air Force personnel will work alongside Chilean civilian medical personnel. The deployment is sponsored by the U.S. Agency for International Development (USAID). A new poll released Tuesday shows Chile's outgoing President Michelle Bachelet's popularity remains high despite some criticism of her government's response to the earthquake. The survey shows 84 percent approve of her performance in office. Ms. Bachelet leaves office Thursday, when President-elect Sebastian Pinera takes over. Tuesday is the final day of a three-day national mourning period for the hundreds of people killed in the quake. National flags are flying at half-staff across Chile in honor of the victims. In New York Monday, United Nations Secretary-General Ban Ki-moon said the destruction in Chile is beyond description. Mr. Ban said that although grief is widespread, there is a sense of unity among the people that he called "heartening." Mr. Ban was in Chile last week to assess the damage. He took part in a telethon in Santiago to raise money for victims and visited the badly hit city of Concepcion, which was closest to the quake's epicenter. Mr. Ban is expected to brief the U.N. General Assembly on Chile Wednesday. He has pledged up to $10 million to Chile from a U.N. fund for quake relief. The government in Santiago has said reconstruction could cost about $30 billion. Government officials are struggling to come up with an accurate death toll. They already have lowered the official number of people killed from more than 800 to 452. Authorities say they will add victims to the count only after their remains have been positively identified. Some information for this report was provided by AFP, AP and Reuters. .
