I believe Zeppelin's have gone the way of the steam engine for the same reason. It's simply an unstable platform of transportation. Steam engines used to blow up all the time and Helium is extremely flammable.

Helium is extremely expensive, rare and likely to escape Earth's atmosphere, but not reactive under any conditions I know of. Hydrogen, on the other hand, is extremely flammable.
