Policemen guard the Salgado Filho airport in Porto Alegre, Brazil July 17, 2007. A Brazilian airliner crashed and burst into flames on Tuesday at Brazil's busiest airport, and as many as 200 people were feared dead in the country's second major air disaster in less than a year. The plane, flying from Porto Alegre in southern Brazil, lost control on landing in Sao Paulo's Congonhas airport.
