Lighter Than Air

I was born in 1955.  The first successful airplane flight was in 1903.  When I was growing up, I knew people who could remember a world before airplanes.  So, I looked up early airships and I did not find any matches to this particular one, but I did find a similar airship, the Baldwin Dirigible from 1908.  It was the first airship purchased by the U.S. Army.  No doubt, as the years went by, there would have been a certain amount of design change, so this photograph could be a latter model.  Then again, this might be a civilian aircraft, or it could be from another country.
