U.S. Air Force Senior Master Sgt. Scott Piper, 60th Air Mobility Wing career assistance advisor, describes to his 11-year-old son Sean Piper, how football formations work November 11, 2018, at Levi’s Stadium, Santa Clara, California. Ten Airmen and their families had the opportunity to attend a 49ers practice, talk about experiences and get in-depth about what it means to be an Airman and what it means to be a 49er.
