'This morning at 7:40, a Greenpeace campaigner, aboard a motor powered hang glider, has flown over the plant of Bugey (35 km east of Lyon), penetrating prohibited airspace .
Illustrating the vulnerability of nuclear facilities to an air based threat, he managed to drop smoke bombs on one nuclear reactor and landed inside the site.'
