*Is there interest in talking about lighter-than-air aircraft.* I am devoured by films like Hindenberg and Dirigible. Though a failed commercial technology, lighter-than-air is historic and a rare adventure into unfulfilled scientific tech. We seem to be imune to disbelieving the future as a nation. I was born in 1932 and can just remember the thrill -and drone- of a dirigible over Long Island headed toward Roosevelt Field.
