5: What Are You Doing?????
I'm no scientist but even I know that there can be toxins in the air that you may not be able to smell, Co2 being an example. So when the scientists all take their helmets off because they detect a breathable atmosphere, I was screaming ''what are you doing?????'' (in my head.) What about diseases, microbes and other stuff that could be in the atmosphere? But they all act like morons and take their protective helmets off and leave themselves open to any infection that might be waiting. And even before you go exploring the cave, shouldn't you map if first? It would make everything much easier.
