hydrogen is VERY flammable, which makes it an unpleasant choice.

How do airships fly?
Just like how a ship floats in the sea because it weighs less than the amount of water it displaces... an airship weighs less than the amount of air it displaces.This is accomplished through the use of lighter-than-air gasses such as helium. In the past hydrogen was used for this, but due to its high flammability this is no longer done. Helium is completely non-flammable and thus is perfectly safe lifting agent.The pilot adjusts the airships bouyancy by either adding more gas, venting gas or by dropping ballast (usually water tanks or sandbags) Once the airship has neutral bouyancy, it can be steered using the elevators and rudders.It is similar in principle to a submarine, which uses 'air' in the ballast to float to the surface and water to descend. Airships rise when 'air' in their hull tanks is replaced with a 'lighter than air' gas, such as Hydrogen or Helium.Just like how a ship floats in the sea because it weighs less than the amount of water it displaces... an airship weighs less than the amount of air it displaces.This is accomplished through the use of lighter-than-air gasses such as helium.

Can Hydrogen fly?
No, Hydrogen is a gas. The verb "fly" can not be applied to a gas.
A gas with one proton?
Hydrogen
What fraction of the average kinetic energy of hydrogen gas at 100K does hydrogen gas have at 40K?
40% -- it is directly proportional to the energy (in Kelvin)
What makes a balloon float?
All balloons do not float. Those that do are filled with a gas that is less dense than the surrounding air, so that is is displaced upward by weight of the denser air. Small balloons are typically filled with helium, a much lighter gas than the nitrogen and oxygen in the atmosphere. Larger balloons may be filled with heated air, which occupies a greater volume and is therefore "lighter" than air outside the balloon. Some dirigibles (airships) were filled with the lighter but flammable gas hydrogen. Hydrogen can be split from water and used to fill thin plastic bags, which will also rise into the air like balloons.
What flammable gas used to be used in airships?
Hydrogen used to be used in airships.
What accident led to change hydrogen gas in airships?
The Hindenburg disaster
What gases are in an airship?
Helium has replace hydrogen in airships
Which floatation gas has been replaced by safer helium in airships?
The gas that helium replaced was Hydrogen
What lighter than air gas was once used to power airships in cause the Hindenburg disaster?
The gas was Hydrogen.
What gas do you use in airships today?
In their early history, buoyant airships (zepellins, blimps) were filled with hydrogen, a highly flammable gas. Since the Hindenburg disaster, hydrogen has been supplanted by helium, a much more expensive material, but one that is inert and hence much safer.
Do airships use gas?
Airships do use gas, to provide lift.
What type of gas filled the Hindenburg airship?
It was hydrogen. That's why it caught fire. Modern airships use helium.
What gas helps airships float?
the gas that helps airships is i hate you wikianswers.com
Why is gas no longer used for airships?
gas is still used in airships to provide lift.
What other properties of helium makes it good for filling airships?
It's very light (only hydrogen gas is less dense than helium), it's relatively cheap, and (most importantly) it's not flammable (hydrogen gas is--the Hindenburg was filled with hydrogen gas).
What element was once used to fill airships?
Hydrogen was the gas that was once used to filled airships. It is extremely plentiful and easy to produce. However, it is also extremely flammable and caused a few accidents. Helium is now used.
