Re: Hindenburg
The concept is interesting and has merit for some applications. The idea is combine the lift from He with a modified flying wing so that is can use shorter runways for the same cargo capacity. There may be no real good military applications as they not terribly fast and are rather large targets. But there may be some civilian applications, both passenger and cargo, where they would be a fit (certain short haul passenger flights and heavier cargo). Often military research is judged a failure when the military applications are not viable but the concept is viable.
