So, I for one think the flammability problem of hydrogen airships is overblown.
But for the love of the above, if you're trying to inspire confidence in a hydrogen airship designed to inspect flammable fluid pipelines do not call it the "Lighter"
This connotation is too bad because HyLighter is a great multi-way pun (highlighting defects; going high in the air; with a lighter-than-air vehicle; based on hydrogen).
