The Magonia blog posted a review today of a new book on the great airship sightings of 1897: The Great Airship of 1897: A Provocative Look at the Most Mysterious Aviation Event in History.
Amazon has the publication date as February 11, 2010, but I’m guessing you can still order it.
This isn’t the only book on this subject. Michael Busby published one in 2004 (Solving the 1897 Airship Mystery).
I have that one, but I’m guessing I’ll get this one, too. If anyone tells you these were alien craft, you need to direct them to these books, since there is solid evidence that this was nothing alien.
