JuliaL, brilliant.
I don't know where I got the 12 m^3 per kWh from. brainfart.com? Possibly a case of "don't drink and derive".
Seriously, I don't know how that number slipped in, probably a confusion of /kg and /kWh - thanks for catching it. The result looked too good to be true, eh?
So, your idea of using parts of the Aluminum structure sounds very interesting. I wasn't aware of that reaction. Yes, they land in a nice forest - they might have the good sense to land near a forest on purpose.
Of course, if they rip 6 metric tons of aluminum out, that will save them almost the 7000 m^3 lifting gas, doesn't it? This would make replenishing the gas pointless. But dropping ballast (from the hull or the engines), is too boring, I want them to have to do some mad science, either electrolysis or chemistry, to make it.
Could the electrolysis be driven simply by burning wood? They'd need a lot of wood, but that shouldn't be a problem for our friends.
The will-they-make-it-back is definitely a subplot.

So how, exactly, does God know that She's NOT a brain in a vat?

Bang, they'll have a wood gas generator! Steampunk indeed. Haha my grandparents had a cur running on wood gas after the war...

Why, I have a good mind to report you for animal cruelty.

On second thought, it was probably your parents' idea.

They didn't have anything back then! He was lucky to get wood gas. Others ran just from getting stones thrown at them!

Burn the fuel and heat the remaining gas in the envelope.
Hot gas (He, H or air) has more lifting power than cold gas.
The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.

It is particularly wise to burn fuel in order to heat hydrogen in the presence of atmospheric oxygen. The crew and their Swedish nuns certainly won't worry about going home once that process is underway.
