Walking with Superman: Day 357

A tragic death during a routine National Guard parachuting exercise was the first indication that something was wrong at Montana's Fort Harrison. By the time Superman arrives, there's no chance that such an accident could happen again, because none of the planes can get off the ground. In fact, nothing can get off the ground! The local gravitational pull has become unbearable, and it'll soon become unbearable for the rest of the planet if Superman can't find a way to stop it! But while the Man of Steel evacuates the soldiers and staff, gravity bends sunlight, dilates time, and strains Superman's mighty muscles more and more. If Superman doesn't hurry, then this will soon become his most crushing defeat!
