The plot of Starship Troopers centers around one major failure and
the devastation it caused. When the pilots and technology of their
spaceship fail to avoid the asteroid headed towards earth, the communications
array on the ship is destroyed. Since this was their only way to communicate
with Earth, the ship was unable to give Earth a warning about the approaching
asteroid. Additionally, once the asteroid arrived, the orbital defense system in
place around earth failed to detect the asteroid in advance or destroy it and thus
an entire city was destroyed by the impact.
