OK, a couple of pictures from the Technisches Museum in Vienna. The first is of the oldest (1841) existing railroad locomotive in mainland Europe (There are at least a couple of older locomotives in England, and a couple of more in the US). The second photo is an original Lilienthal glider; we previously saw one from Warsaw. I think there are six originals in existence, in Vienna, Warsaw, Moscow, London, Washington DC and I think one in poor condition in Munich.
