Questions are being raised about whether two Russians held on terror charges in Spain were planning to launch airborne attacks on paragliders. The two Russians took paragliding lessons this year in a southern Spanish region renowned for the sport, authorities said over the weekend. A Turkish engineer also under arrest paid for the lessons. No attacks have been carried out using paragliders, experts said. However, paragliding did feature in one recent stunt by an environmentalist that must have given chills to authorities, including those from countries that use drones to target and kill suspected Islamic terrorists. The activist was arrested last May after dropping a billowing smoke bomb onto the roof of a French nuclear reactor. (AP Photo/Lagazta, Greenpeace, File)
