Once a year, the Dornier Museum in Friedrichshafen on Lake Constance becomes the Flying Museum. For DO Days, a spectacular weekend of flying from 9 to 10 August 2014, the museum is transformed into an aircraft hangar. Those with a passion for aviation or transport heritage are in for a treat, with numerous guest aeroplanes on display outside. But there's more than just flying machines on offer. The varied programme has plenty to keep visitors big and small entertained: from passenger flights and impressive model aeroplane displays to painting your own biplane or dancing to classic rock tunes.
