I'm old enough to remember Airship Industries (1979):
>The AD500 was "a new-generation airship making use of advanced materials and technology." It was 164 feet (50 m) long and contained 181,200 cubic feet (5,130 m3) of helium.
>Unfortunately, on 8 March 1979, the month-old AD500 was seriously damaged when the nosecone failed while the ship was moored in high winds.
