>>10811248If an aerial structure based on buoyancy has several pockets of lighter-than-air instead of just a large one, it will be heavier and less efficient but in the case of containment failure, the first case drops in altitude and may allow for an emergency landing while the latter case results immediately in catastrophic failure and everything is destroyed and any occupants die.
That said, why not just invest in a sturdier outer shell for the blimp, right?
