@SteveThompson @derek gonna be really interesting for the future of humanity if the medical-aid-delivering airships end up exhausting the global supply of helium that is needed in part by the medical profession to run diagnostic equipment.
(Though, in researching the state of things for this post, I found there are low- and no-helium MRI machines in development)
@kboyd @SteveThompson not a problem. See, I've just discovered that there is *another* lighter-than-air gas called hydrogen. We can just use that for the airship.
@derek @SteveThompson sounds plentiful, and safe!
