Carver Faull, a participant in the Pilot for a Day program on McChord Field, smiles after members of the 627th Civil Engineer Squadron’s explosive ordnance disposal team let him make the call to detonate explosives, Feb. 20, 2015, at Joint Base Lewis-McChord, Wash. After Carver called the detonation over the radio, two and a half pounds of C-4 ignited from across the air field.
