jealous diapered astronauts

I recently read a news article about a female astronaut, who was dating a male coworker and learned that he was cheating. She drove for 12 hours to attack the other woman involved:

Nowak — who was a mission specialist on a Discovery launch last summer — was wearing a trench coat and wig and had a knife, BB pistol, and latex gloves in her car, reports show. They also found diapers, which Nowak said she used so she wouldn’t have to stop on the 1,000-mile drive.

Link.

What perturbs me is that she is organized enough to strategize about diapers, demonstrating more foresight than 90% of the population. Yet she lacks the self-control to do what the rest of us would, which is to storm to the garage angrily, then burst into tears and go back indoors to eat Haagen Dazs and watch "Lost".
