It's Perfect
Bugs? Impossible!
Fred: A glitch? No, that's not possible. I programmed it myself. It's perfect.
Mars team: Not exactly. Your program keeps miscalculating our orbital entry trajectories. Here's the data.
Fred: Well there's the problem. Gary's been running his hone and transfer equations to include gravitational effect, bearing as the inverse cube of the distance.
Mars team: I'm a decorated astronaut. I don't make those kind of mistakes!
Fred: Well, now wait a minute. I'll show you. I'll add to the same calculations, using what we like to call "the right way"...
