Metal rain clattered into the carrier’s superstructure as shrapnel from the blast whickered through the air to strike them. One twisted iron rivet that must have been traveling at the speed of sound smashed into the armor glass with a giant thud, to leave a delicate star pattern at the point of impact.

Two heartbeats later a five-hundred-kilogram bomb speared into the flight deck of the USS Hillary Clinton, two hundred meters aft of the flag bridge. The dumb iron bomb detonated a few feet from the Clinton’s captain, Guy Chandler, and the group of unconscious technicians who had been carrying out routine maintenance checks on the aft catapults when the floor of the universe dropped out beneath them all. They all died without ever knowing they had journeyed between worlds.

The deck of the Clinton was armored against mace munitions. The number three catapult, however, was not. Indeed, like all of the ship’s catapults it was a terribly vulnerable, high-maintenance bitch of a thing, which demanded constant loving care and attention lest it decide to malfunction with a fully laden Raptor hooked up and ready to roll. It was similar in form to the last generation of steam-driven catapults, consisting of a pair of very long tubes, topped by an open slot, sealed with rubber flanges. But rather than drawing pressurized steam from the ship’s propulsion plant, the fuel-air explosive, or FAX, catapults used a binary fuel mix that was theoretically easier and safer to handle.

The theory, however, did not account for a bomb strike taking place in the middle of a launch simulation. The technical crew who died at catapult three had been running her through a series of prelaunch tests in preparation for the day’s exercises. When the bomb struck, the seventy-five-meter-long catapult tubes were full of the highly volatile fuel-air mix; enough, when it detonated, to rip a huge furrow out of the angled portside flight deck.

Enough, as well, to trigger a much more powerful and catastrophic explosion in a liquid oxygen tank recessed in a nominally secure area just below the lip of the flight deck, behind the Optical Landing System. It blew with a blinding white light and a head-cracking roar that approximated the effect of a subnuclear plasma-yield warhead. Most of that blast wave traveled up and outward, raking the flight deck of all human life and obliterating the frail dive-bomber that had launched the attack.

But it did not kill the Clinton. The voided double hull and monobonded deck plating absorbed and then shed 60 percent of the blast. That still left force enough, however, to trash dozens of aircraft chained down outboard of catapults one and two, and to sweep the flight decks clear of any personnel who had not been instantly vaporized.
