Hill fighter wings to continue night flying through second week of April Published Feb. 3, 2021 By Micah Garbarino 388th Fighter Wing Public Affairs HILL AIR FORCE BASE, Utah -- F-35 pilots and maintainers from the Air Force Reserve 419th Fighter Wing and active duty 388th Fighter Wing will be working later shifts as they conduct local night-flying operations most weekdays through the second week of April. During this period, most flying is scheduled to be completed between 7-10 p.m., but there will be a few occasions where flying ends later. These times may change based on a number of factors including weather, airspace availability on the Utah Test and Training Range, and other support elements. Hill’s fighter wings must train at night to maintain their combat readiness and all-weather capabilities and night flying is limited to what is required for pilots to remain proficient in those skills. Hill AFB is home to 78 F-35A Lightning IIs. The 388th and 419th are the Air Force's first combat-capable F-35A units, and fly and maintain the jet in a Total Force partnership, which capitalizes on the strength of both the active duty and Reserve.
