The crowd thought they were watching a stunt.

Then the sky exploded.

Two fighter jets slammed into each other midair over an Idaho air show, sending fire, metal and smoke roaring toward the ground as families screamed and ran.

Spectators at Mountain Home Air Force Base watched in horror as two jets, flying dangerously close during the Gunfighters Air Show, clipped each other and locked together.

In an instant, the roar of engines turned into a sickening crack and a blooming fireball, black smoke clawing into the Idaho sky.

Parents grabbed children. People dropped their phones and ran, convinced they had just watched four service members die in front of them.

But as the wreckage tumbled toward the runway, four parachutes burst open against the smoke.

The announcer’s trembling voice cut through the panic, insisting, “We had four good parachutes,” and asking the shaken crowd to pray.

Emergency crews raced a mile south toward the landing site as the base went into lockdown, haunted by the memory of past fatal crashes.

On a day meant to celebrate precision and power, survival itself became the only miracle that mattered.
