Helicopters are parked near the site where Mexico’s Interior Minister Francisco Blake and seven others were killed in a helicopter crash on a hillside south of Mexico City November 11, 2011. President Felipe Calderon said conditions were cloudy when the helicopter came down so that an accident looked probable. But in a televised address, he said no explanations for the crash could be ruled out as he paid tribute to Blake, calling him „a great Mexican.” REUTERS/Margarito Perez (MEXICO – Tags: POLITICS OBITUARY)
