The weekend of Sept 16-18 was a historic event in the European Twitter and Space sphere. For the first time, a European SpaceTweetup was held at the European Astronaut Centre in Cologne. After the succesful NASATweetups ESA and DLR thought the Tag der Luft under Raumfahrt would be a good event to invite a select few to a day filled with interesting talks, meet&greets with astronauts and excursions on the EAC premises.
