Four crew ⁠members involved in a mid-air ⁠collision of military jets at an air show ejected safely on Sunday outside Mountain Home Air Force Base in Idaho, the US Navy said.

Two E/A-18G Growler ‌jets collided in mid-air two miles from the base during the two-day Gunfighter Skies Air Show, said Commander Amelia Umayam, a spokeswoman for Naval Air Forces, US Pacific Fleet.

The two jets with four crew collided “while performing an aerial ⁠demonstration” as part of the air ‌show, Umayam said, noting that all four crew members ejected safely.

“The incident is under investigation. More ‌information will be released as it becomes available,” Umayam said.

The airbase was locked down after the crash, according to Mountain Home’s Facebook page. The ‌air show’s official site lists the US Navy’s E/A-18G “Vikings” Growler Demo Team as ‌one of ‌the scheduled performers. The jets involved in the collision ‌were assigned to Electronic Attack Squadron 129 from Whidbey Island, Washington, Umayam ⁠said.

Sunday marked the first Gunfighter Skies Air Show in eight years. ⁠A hang-glider pilot died in a crash during the last show in 2018.
