It’s probably just a coincidence, but soon after my post on airships this story covering the World Forum on Enterprise and the Environment turned up. Among other things, they were discussing the future of airships, and that they could be used for some transport in under 10 years.
Also, the US Army has recently selected a winner in the LEMV (Long-Endurance Multi-intelligence Vehicle) program for a recon airship with an endurance 3 weeks. Northrop Grumman’s design is a hybrid design (like HMS Indefatigable!) as this approach give the craft far better control. The contract is for 3 at the moment and they could be in service as early as next year.
