Although this first test flight was carried out with a crew on board, the LEMV is designed to be operated without a crew. - gurjeet Wed, 03 Oct 2012 02:53:54 +0100 http://www.ecogeek.org/efficiency/3798-new-airships-taking-flight#comment-47248 Airships are great means of transportation, non-polluting, quiet and take up far less space than airplanes and their airports. The other uses reported such as communications links after disasters are fascinating too. I stand by my title question: what took so long? Two answers could be: cheap oil for 50 years, and the technical difficulties behind preparing large quantities of non-combustible helium for airship flotation. Bring them on! I'd love to travel over the Atlantic in a dirigible someday soon. - Carol S. Sun, 16 Sep 2012 16:30:57 +0100
