Walter Momper (ruling mayor of Berlin in 1989) expected the Berlin Wall to open: "We expected that one day the storm would come across the border from behind, actually, since Otto von Habsburg and the Pan-Europa-Union had the pan-European picnic on the border between Hungary and Austria on August 19, 1989 in Sopron. Hundreds of them came. It was stupid that people from the GDR should cross the border via Hungary and Austria. if there was a border crossing directly with them."
