419th Tactical Fighter Wing, Hill AFB Utah.
If the date on the photo is correct, this was January 1984 - as the last squadron in the world flying F-105s officially became a F-16 squadron that month.
On June 4, 1983, the 419th Tactical Fighter Wing, Utah's only Air Force Reserve flying unit, began retiring the renowned F-105 Thunderchief with a 24-ship flyover of Hill Air Force Base. Personnel who had distinguished themselves in combat operations years before in Southeast Asia led and participated in the singular final tribute.
