Royal Canadian air force Cpl. Yannick Deschesnes, an aircrew flight equipment technician from the 425th Tactical Fighter Squadron, tests a joint helmet-mounted cueing system for a CF-18 Hornet pilot at Eielson Air Force Base, Alaska, May 7, 2015, during RED FLAG-Alaska (RF-A) 15-2. After testing and certifying aircrew flight equipment, Deschesnes will transition to the role of crew chief and launch jets during RF-A to reduce the amount of manning required while on temporary duty.
