Due to the fact that its extremely flammable
because it is
It was hydrogen. That's why it caught fire. Modern airships use helium.
Hydrogen was one of the earliest gases to be used for inflatable flying balloons, but following the Hindenberg disaster helium is now used, as it is chemically inert.
Helium is used for inflating balloons and dirigible airships.
Helium
An advantage is that it's lighter than air and it isnt flammable and it can lift abjects of the ground A disadvantage is that its rare and costs alot and also cant lift that heavy of things:)
There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.
That'd be hydrogen.
Helium is inert. Will not burn like hydrogen does so well.
hydrogen is VERY flammable, which makes it an unpleasant choice.
Hydrogen used to be used in airships.
because hydrogen used to be in those airships and since hydrogen is flammable it was very dangerous
they blew up
Hydrogen
Hydrogen and helium are two elements that are kinda-sorta interchangeable in airships.
Modern airships use Helium for lift which is non-combustible whereas in the past airships such as the Hindenburg used Hydrogen for lift which is highly combustible. In addition, modern airships take advantage of new alloys and polymers which give them a much stronger airframe.
Hydrogen was once used to fill airships. Quite dangerous due to how flammable it is.
