That sounds like a very enjoyable endeavor! I was wondering, what are the benefits and drawbacks to flying a lighter-than-air ship under 1,000 feet? Or even closer to the ground/tops of buildings? <500 feet? Are there simply too many regulatory issues?

I have a dream that some day there will be airships floating around cities, ferrying passengers and freight, and they will float only 30-100 meters above the tallest buildings.

The issue is they’re quite slow and not exactly nimble craft so flying low you need to be very sure you’re well clear of the surrounding hazards.
