The fire department said the Boeing 757 had taken off from Juan Santamaría Airport just west of the capital but decided to return after detecting a failure in the hydraulic system. Héctor Chaves, director of the Costa Rica Fire Department, said that upon landing, the aircraft skidded, turned, and broke in two, exposing its cargo. "Units mobilized to remove the pilot and co-pilot," Chaves said. "Then they applied foam to prevent a spill, and now they are working on an earthen dike to avoid any fuel from reaching the drainage system."
