I am not sure if the aircraft in the article is actually light than air or if it is a hybrid but I can assure you that hybrid airships are in no way shape or form vaporware. The US Military is currently developing multiple models and her is a recent video of one that can stay in the air for 21 days with a 1 ton surveillance package. Note the difference between these and normal airships though, they are not 100% buoyant in air and require active thrust in order to fly with a somewhat aerodynamic body. http://www.youtube.com/watch?v=R1G-L7qvTKI http://www.youtube.com/watch?v=R1G-L7qvTKI
