Plot hole: Van Gunther has the two rockets aimed at the Geneva Convention. They launch with Steve attached to one of them. Wonder Woman chases in her invisible jet and shoots down the other rocket. She then gets out and uses her crown like a boomerang to break the chains holding Steve to the second rocket and rescues him off it. She or her crown never touch the rocket, but it crashes into a mountain. She did nothing to it to disrupt its course towards the Geneva Arms Conference. There was nothing to make it crash or hit prematurely, and the sudden weight change of Steve falling off would not have been enough to cause it.
