Zeppelins Over Duluth
From the book The First Time Germany Invaded Duluth, Minnesota by Peter S. Svenson:
“July 1, 1917: The Weltanshauung, a German hydrogen war-zeppelin, lost power over Bavaria. Captured by the wind, for the next two weeks it blew north across Europe and then the Arctic Circle. The furious crew tried fixing the engines but never succeeded. Technically, they set the World Record for the first arctic crossing by air, a feat later repeated by Shackleton.”
From “Zeppelins Over Duluth!” Duluth Herald, July 16, 1917:
“The Weltanshauung contained an internal airplane hangar with six black tri-planes that emerged from the nose of the craft like hornets. A Canadian fighter squadron looked for the zeppelin over Lake Erie and almost collided with it in the dark. It was a cliff face hanging in the sky, dwarfing them with the black-cross-on-white symbol of the German Air Force. But the Canadians lost it in confusion and fear. Soon a lake steamer spotted it drifting within sight of the North Shore of Lake Superior, toward Duluth. The authorities mobilized the American helium zeppelin, the Federalist, from its floating hangar in the Duluth harbor.
