A Philippine military plane on a routine training flight slammed into a mountain in northern Luzon region on Tuesday, killing all four air force officers on board, an air force spokesman said. It was the latest in a string of air accidents in the Southeast Asian country. Lieutenant-Colonel Restituto Padilla, an air force spokesman, said the four-seater T41D trainer plane radioed for help minutes after it took off from Baguio City airport, Reuters reported. "It tried an emergency landing," Padilla told reporters. "It failed. The plane ploughed through a wooded mountain slope at the end of the airport's runway. Padilla said it was the sixth light aircraft accident in less than a month. A military helicopter crash on April 28 killed nine people, including four senior government geologists surveying areas hit by landslides in the north. Between the two military accidents, four civilian light planes went down in different parts of the country, killing seven people.
