But the article doesn't say how fast it can travel, which is extremely important in reaching disaster zones. Even if you're travelling from, say, Miami to Haiti is 1000km, so I guess it would take 30 hours? But providing aid to Tonga after the recent volcano seems unlikely with this airship. Sergey Brin also has a ship that provides aid: https://www.indiatimes.com/technology/news/sergey-brin-secret-disaster-relief-team-with-ex-us-military-516282.html https://www.indiatimes.com/technology/news/sergey-brin-secre... - so I don't know what advantage he sees in this airship.
