Hanscom defender saves a life
Staff Sgt. Humphrey Chadbourne, 66th Security Forces Squadron patrolman, stands by his cruiser with an automated external defibrillator machine at Hanscom Air Force Base, Mass., March 12. Earlier this year, Chadbourne was the first to respond to a medical emergency where his rapid and decisive actions ultimately saved the life of a contractor who suffered a heart attack on base.
