QDL[edit]
The article says the solid propellant contains either QDL-1 or QDL-2. But it doesn't say what that is, doesn't link it, and Wikipedia doesn't have an article about it. Isn't it the case that it's a name for the HTPB/aluminium mix, rather than some additional chemical? Either way, the article should explain what it is. -- Finlay McWalter··–·Talk 06:55, 3 July 2018 (UTC)
