Helium was the primary choice for lighter than air because it does not burn.
In the 40's only the allies had a supply - against better judgement the designers used very unstable (lighter than air) hydrogen for lift in zeppelins because of supply issues. It didnt work out too well for them, hydrogen abandoned in due course.
put a couple of electrodes in water, supply a voltage - hydrogen will bubble off one side oxygen the other - pretty easy stuff to make....
