The Airlander first flew in 2016, so it’s been four years. On the linked Hybrid Air Vehicles website, it appears that they’re selling this hard as some kind of luxury conveyance, much like the Hindenburg. There is no video on the site of the Airlander picking up a big pile of logs or a bulldozer. I’d need to see that before I bought one. Airships always seem to be the next big thing, but there are reasons why after a lot of developement they stopped making them in the 1930s. Many airships had catastrophic accidents, and they’re just too freakin’ big.
