Two military aircraft collided mid-air before crashing at an air show in Idaho, according to multiple reports, though the pilots were said to be able to safely eject.

In posts on social media, the Mountain Home Air Force Base Gunfighters confirmed an “aircraft incident” took place at the Gunfighter Skies Air Show on Sunday.

The incident happened about two miles northwest of the base, and first responders are investigating.

Video of the incident circulating on social media appears to show the pilots ejected from the planes.

In a separate post, the Mountain Home Air Force Base Gunfighters said the base would be locked down in the immediate aftermath.
