Håkan Blomqvist of Archives for the Unexplained (AFU) is a UFO scholar who has written an interesting article about the Swedish Understanding Unit Number One. Recommended! Here is the first paragraph:
One of the largest UFO contactee organizations in the 1950s and 60s was Understanding, Inc. founded by Daniel W. Fry in 1955. From a modest beginning with nine members in El Monte, California the organization grew to more than 70 local units in the United States and many members throughout the world. Recently AFU received a donation of old documents from the only European Understanding Unit, founded in Sweden 1963 by Sven-Erik and Ing-Marie Asklund, then living i Bandhagen, south of Stockholm. This event was proudly announced in the magazine Understanding, June 1963.
