Because hydrogen is highly explosive and very flammable. It is very dangerous. Even the slightest spark could explode the whole ship.
There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.
Helium has replace hydrogen in airships
Helium is inert. Will not burn like hydrogen does so well.
Weather airships are aircraft that are lifted by gases lighter than air. It is dangerous to fill them with hydrogen because hydrogen is flammable, which poses a high risk of fire or explosion. In the past, airships filled with hydrogen have experienced catastrophic accidents due to this flammability.
An example of a gas element is helium, which is a noble gas commonly used in party balloons and airships.
Hydrogen used to be used in airships.
because hydrogen used to be in those airships and since hydrogen is flammable it was very dangerous

Hydrogen
Hydrogen and helium are two elements that are kinda-sorta interchangeable in airships.
Hydrogen was once used to fill airships. Quite dangerous due to how flammable it is.
Hydrogen airships can vary in size, but most commercial airships are around 200 to 250 feet in length. However, historical airships like the Hindenburg were much larger, at approximately 800 feet long.
That'd be hydrogen.
The Hindenburg disaster
