Brazil delivered five military planes to Colombia on Thursday in a move that Colombia's biggest rebel group characterized as meddling in its four-decade fight to establish a socialist state, according to Reuters. The Super Tucano turboprop planes, made by Embraer, are part of a bigger order of 25 aircraft worth $235 million. Brazil uses them for training pilots and surveillance over its vast Amazon region, which borders Colombia. "The Colombian air force chose the Super Tucano as the most efficient option for the important mission of internal security," Embraer quoted Colombian Gen. Ricardo Rubianogroot as saying in a statement.
