Two jets crashed during the second day of the Gunfighter Skies Air Show at Mountain Home Air Force Base in Idaho on Sunday, prompting a lockdown at the installation, according to local reports and eyewitnesses. 

In a statement posted to Facebook, Mountain Home Gunfighters said “an aircraft incident has occurred at Mountain Home Air Force Base during the Gunfighter Skies Air Show two miles northwest of the base.”

“Emergency responders are on the scene, an investigation is underway and more details will be released as they become available,” the statement added.

Videos posted to social media appear to show two jets colliding midair before four parachutes deploy. The aircraft then fall to the ground before exploding, sending thick black smoke billowing into the air.

David Katz, who attended the air show with his family, told Fox News Digital he witnessed what appeared to be the two aircraft colliding before one erupted into flames.

“We saw the smoke and fireball,” Katz said. “Apparently they collided there. One of the planes was impacted and started burning in the air.”
