Did you hear that initial reports are citing a build-up of dihydrogen monoxide vapour as the cause of the explosion?

Dad used to be a fuel handler for Titan II ICBMs and the second stage of that rocket uses the same fuel and oxidizer. If exposed to the air, the oxidizer would become red fuming nitric acid (or, as they called it at the missile sites, BFRC for Big loving Red Cloud), which could melt your lungs.

He posted a warning to his friends in the area to watch out for BFRC.

Second stage of what rocket, the Antares? The Antares doesn't use RFNA on any stage, the first stage is regular old kerosene/LOX and the second stage is a solid rocket.

Supposedly there was some big nitrogen tank on board. Am I wrong or is that why the explosion was so huge?

Serious answer after all the razzing, gaseous nitrogen (N2) is extremely stable and unreactive, as it has a triple bond between the two individual atoms. Triple bonds are extremely difficult (read: take a lot of energy input) to break apart so nitrogen can be put into other compounds. Those compounds are notoriously unstable because of said input energy, it's still part of the atom by dint of the triple bond not existing. When those compounds decompose and the nitrogen atoms re-form that triple bond, all that energy that was put in to break it is released at once.

See for example this blog post on a compound containing 6 Nitrogen atoms per molecule. A highlight:

quote:

...Making something like this that can actually be handled and stored is a real accomplishment.

Not that it's what you'd call a perfect compound in that regard - despite a lot of effort, it's still not quite ready to be hauled around in trucks. There's a recent report of a method to make a more stable form of it, by mixing it with TNT. Yes, this is an example of something that becomes less explosive as a one-to-one cocrystal with TNT. Although, as the authors point out, if you heat those crystals up the two components separate out, and you're left with crystals of pure CL-20 soaking in liquid TNT, a situation that will heighten your awareness of the fleeting nature of life.

1) Lots of intercepts going on. Russian Bear diplomacy continues; it's not every day Portugal has to scramble fighter jets.

2) People are accusing France of shenanigans with delivery of those assault ships. According to the report, France's president will decide "at the moment of hand-over" weather or not the ship will in fact be handed over.

Dad must have misspoke when he said second. Yeah, dinitrogen tetroxide is pretty nasty stuff that was used as the oxidizer in Titan IIs and turned into a BFRC it got out.

What third stage? Neither Titan II or Antares have one. Antares is nothing like a storable-liquid-fuel ICBM.

Titan II:
First stage: hydrazine/UDMH/dinitrogen tetroxide.
Second stage: hydrazine/dinitrogen tetroxide.

Antares:
First stage: kerosene/LOX
Second stage: solid fuel (aluminum/binder/oxidizer).

Thanks for explaining this. Chemistry is my worst subject (AFAIK) and I never understood why stable, boring nitrogen was found in so many things that explode.

Dumb question: I remember from high school nitrogen has a triple bond. Could you (in theory) make even better explosives out of something with a quadruple bond, like silicon or carbon?

Fair enough. From my limited recollection of high school chemistry, that sounds implausible simply because electrons, as with all like-charged particles, will tend to repel each other and squishing eight into the same area isn't too likely.

No you cannot get 4 bonds to another atom with carbon/silicon due to how the electron orbitals are arranged.
