Advertising blimp lost in Czech airspace


A ten-metre advertising blimp is lost in Czech airspace after coming untied from a building in Stará Boleslav on Monday. The unmanned helium blimp damaged two roofs and a chimney before disappearing into cloudy skies. While it poses no danger in falling to the ground, air traffic control at nearby Prague Airport was forced to adapt flight plans according to its expected speed and course.
