Betty Tackaberry "Tack" Blake (October 29, 1920 β April 9, 2015) was the last surviving member of the first training class (Class 43-W-1 at Sweetwater, Texas, on April 24, 1943) of the Women Airforce Service Pilots paramilitary aviation service.
The WASPS flew aircraft ferrying/delivery missions, towed aerial targets, and some even participated in flight testing and evaluation of advanced jet and rocket-powered aircraft.
In performing these missions, the woman effectively replaced male pilots, who could be utilized in combat roles.
