A company that makes airships presents them as a way to reduce the emissions of air travel.

However, that company's airships apparently won't reduce emissions the tiniest bit, since it plans to use them as a sort of aerial cruise ship.

I am puzzled by the claim that they will travel faster than trains. Fast trains today sometimes take passengers station to station averaging 175 miles per hour, while these airships seem to be tested only up to 50 knots.
