Im looking for this scene from superman 2 from 1980 where these astronauts are on the moon and they all get killed, by Zod, Ursa, and Non I remember one of the astronauts death where you actually saw him explode into a giant balloon like thing but I cannot find that scene anywhere if you can tell me how to find that one scene you will be my hero.

You don't actually see him explode here, but is this part of the scene you're looking for?
