Gen. Stephen Wilson, vice chief of staff of the Air Force, interacts with an instructor through virtual means in a new unclassified classroom in the 316th Training Squadron computer lab on Goodfellow Air Force Base, Texas, May 29, 2020. Since COVID-19, the curriculum for some courses has been adapted to a hybrid version so that students have the ability to study outside of the classroom and interact with instructors virtually, guaranteeing student and instructor safety during the pandemic.
