> Missile fuel is a binary: it can either be solid or liquid.
Lol what?! No, binary fuels have two components that are both neccesary for operation.
Also like commented elsewhere, peroxide fuels are... an adventurous choice
What these basic errors mean for the perception of the rest of the article is left as an exercise for the reader.
It’s a bit odd as well as they then go into describing hybrid and gel systems that are both and neither respectively. But overall it’s a pretty informative article and I learned a lot.
I think they meant like the odds are 50/50 - it either happens or it doesn’t (lol).
I think "missile fuel is a binary" is just a very inarticulate attempt to say "there are two types of missile fuel"
