This was generated by seeing a Navy blimp while outside earlier today. I'm not suggesting anything other than a highly limited niche market for lighter-than-air transportation--perhaps, as one poster suggested, something of an alternative to the cruise ship and thus strictly a tourist attraction of sorts. Come to think of it, that may not be altogether ludicrous: there are tourist railroads that don't do anything apart from re-enacting (if you will) rail transportation of decades ago; it's not entirely unfathomable to imagine a tourist airship endeavor.
It would be a wonderful trip. You could say board the Zeppelin early in the morning (6 am) in Victoria. With a speed of say 150 and altitude of 1500 feet, you could make about a thousand miles up the BC/Alaska coast and be back for a late dinner. This is roughly to Anchorage and back. The advantage is it is one day to see all the Glaciers, not a 3 day cruise.
Or it would be great for whale watching. It actually easily has the range to make the Antarctic whaling grounds in a two day trip. Leave late one evening, and in morning you would be over the whaling grounds. Come back the next night. All out of your trip to New Zealand.
1) Does not hit endangered whales.
2) Probably quiet enough to spook them.
3) Your are looking down, so much easier to spot the dark shapes under the water.
4) You are higher, so can see more ocean at any given time.
5) Can loiter over a large group of whales/dolphins for hours if desired.
Or say for astronomy buffs. Many cities have a lot of light pollution. You could put an observatory on one of these. Say leave LA in evening and by true dark, you could be far enough away from cities to not have light issues. And with 5K or say elevation and ability to move, clouds should not be an issue.
I think if you can avoid the Hindenburg disaster, you could easily see some type of niche tourist today. You might also need to have the company do something like move to Switzerland pre-WW2. It would be a common practice if done between 1920 and 1933.
It can also provide what we can do with drones decades earlier, if their was a desire. I can play with situations where in the 1980's on the war on drugs, the USA builds a few of these ships to watch for drug smugglers. Think of a AWAC that says on station for a week at a time. Basically anytime you want surface ship like loiter times, but at 5K feet, it will work.
