Ultimate Fantastic Four #14 (2004)

N-Zone
Reed Richards has convinced General Ross to allow a trip to the N-Zone, once Reed showed him a military application of the device. Dr. Storm isn't happy about it, but he can't prevent it, so the team refits an old space shuttle as per Reed's design specs, and find themselves ready to depart for realities unknown. The transfer from one world to another goes quite smoothly, and the exploring begins.
