Geoff is inspired to build a hi-speed concept-vehicle, the Personal Assault Lander (PAL), that can travel on water and land. It's been a life-long dream of his, and despite the company's deadlines, he decides now is the time to do it. But H&H is havi... (more)ng trouble fabricating a fleet of Subterranean Rovers and is way behind schedule. In a reversal of their usual roles, Mike is being the responsible one, worrying about their core business, while Geoff is focusing on a far-out research and development project.
