Of four American-built (rigid) airships, two ditched in the sea and one was wrecked in violent winds. (The German-built Los Angeles flew safely until retired.)
The British used (hydrogen-filled) rigid airships for passenger mail, but our airship programme came to an end after the appalling tragedy of R-101. France and Italy had similar experiences.
Yet somehow the airship is too seductive a vision for people to give up on it. It floats like a butterfly as it travels quickly (? 80 knots max) and silently to its destination.
Helium-filled airships such as the Stella Artois Star over London have yet to prove themselves in bad conditions. " (Er, the USN flew helium filled patrol blimps in all weathers for many years until withdrawn in 1961 for policy reasons with a commendable safety and availability record. See the K, M and N classes)
N Class Blimp
So comparing the helium filled Zeppelin NT with the hydrogen filled Hindenburg is like comparing apples with oranges and not factoring in eighty years of technological improvement (compare a Dakota with a 787) is bananas.
