You don't use Helium. You use Hydrogen. Hydrogen cannot burn without oxygen. Hydrogen is too tightly packed in an airship to get sufficient exposure to oxygen. Therefore, even in case of a fire, much of the hydrogen just escapes without burning. Airplanes too fell from the sky when the industry was not mature. We didn't just ban airplanes outright.
yup. and we don't dope the envelopes with aluminum powder either.

Likely static charge from a cloud causing hydrogen to ignite. Hydrogen burns freely at all concentrations both very low and very high and is therefore far, far more flammable even than natural gas, so I'm afraid hydrogen airships will always be a catastrophe waiting to happen.
