Then, in an instant, the world around McCain erupted in flames. A six-foot-long Zuni rocket, inexplicably launched by an F-4 Phantom across the flight deck, ripped through the fuel tank of McCain's aircraft. Hundreds of gallons of fuel splashed onto the deck and came ablaze. Then: Clank. Clank. Two 1,000-pound bombs dropped from under the belly of McCain's stubby A-4, the Navy's "Tinkertoy Bomber," into the fire.
McCain, who knew more than most pilots about bailing out of a crippled aircraft, leapt forward out of the cockpit, swung himself down from the refueling probe protruding from the nose cone, rolled through the flames and ran to safety across the flight deck. Just then, one of his bombs "cooked off," blowing a crater in the deck and incinerating the sailors who had rushed past McCain with hoses and fire extinguishers. McCain was stung by tiny bits of shrapnel in his legs and chest, but the wounds weren't serious; his father would later report to friends that Johnny "came through without a scratch."
The damage to the Forrestal was far more grievous: The explosion set off a chain reaction of bombs, creating a devastating inferno that would kill 134 of the carrier's 5,000-man crew, injure 161 and threaten to sink the ship.
...
McCain displayed little of Hope's valor. Although he would soon regale The New York Times with tales of the heroism of the brave enlisted men who "stayed to help the pilots fight the fire," McCain took no part in dousing the flames himself. After going belowdecks and briefly helping sailors who were frantically trying to unload bombs from an elevator to the flight deck, McCain retreated to the safety of the "ready room," where off-duty pilots spent their noncombat hours talking trash and playing poker. There, McCain watched the conflagration unfold on the room's closed-circuit television — bearing distant witness to the valiant self-sacrifice of others who died trying to save the ship, pushing jets into the sea to keep their bombs from exploding on deck.
As the ship burned, McCain took a moment to mourn his misfortune; his combat career appeared to be going up in smoke. "This distressed me considerably," he recalls in Faith of My Fathers. "I feared my ambitions were among the casualties in the calamity that had claimed the Forrestal."
