Böcker av William F. Althoff

Originally published in 1990, Sky Ships is the most comprehensive history of US Navy airships ever written. The Naval Institute Press is releasing this new edition - complete with two hundred new photographs--to commemorate the twenty-fifth anniversary of the book's publication.

Closed to conventional passage, the Arctic Ocean and peripheral seas have nevertheless known European explorers since the sixteenth century. Systematic observation, however, dates only from the last years of the nineteenth century, with the epic drift of Fridtjof Nansen's ice ship Fram (1893-1896), the first scientific expedition of the modern era.
