USS Akron (ZRS-4)
It was destroyed during a flight off the coast of New Jersey by a storm.
Only three people survived the crash.
Admiral Moffett, then the most ardent proponent of airships in the US Navy was onboard and was killed.
Its sister ship, the USS Macon crashed a few years later.
The loss of these two airships marked the end of US Navy involvement with rigid airships.
