The criticism of The Avengers' nuclear-missile scene is that the weapon is marked as a Joint Stand-Off Weapon (JSOW). JSOW is described as a conventional glide weapon. It normally lacks a propulsion system and cannot accept the nuclear warhead assigned to it in the film. The scene uses the appearance of one weapon while giving it a different set of capabilities.
