The easter one is mostly fun and he saves everyone so that is happy, but make sure your happy pills are working before watching this one. It's a great, really deep and questioning episode, very worth your time, but man.
If the substances were coated in self-oxygenating fuel from the rocket, that could lead to them continuing to burn for a bit because with such a substance the process of burning would create the necessary oxygen for further burning by releasing it from the fuel.
Which is complete handwavey crap, because I don't know of anything that man's discovered or invented that does such a thing, but I imagine it'd be something we'd have to work on for serious longterm space travel projects.
And here we go: among the other known oxidizing elements, at least fluorine is capable of sustaining fire, and would pretty much only be used as a fuel element in longterm/deep space projects because there is currently no method known to man of putting out a fluorine fire!
Huh! That is really interesting about the flourine being viable, and I do like your logic about the need for some kind of fuel that would generate more oxygen. As far as I remember, rechargeable batteries are like that- the chemicals made from the first chemical reaction create another chemical reaction from the introduction of electrical current and bring it back to the start. I suppose it would have to be like that, except on a really enormous scale.
(Forgive any glaring ignorance I display. It has been about seven years since my last serious foray into chemistry.)

I haven't watched it yet, though! I realized that I never even finished the Easter special, and uh, watched Seeker instead. :D

But really, I have no idea if you could get fire using something other than oxygen. I'd almost think so, but I don't know.

I think that was entirely the reasoning, and I was so busy agreeing that I totally missed the science. WELL PLAYED, DW TEAM.
