He's seen more than his fair share of perilous situations, but on each job he has to show the crew he knows his stuff. It's usually a quick initiation, and soon Riley is flexing his engineering muscle while helping experts solve problems of enormous proportions. Whether dangling from ropes hundreds of feet in the air or diving close to a construction vessel's propellers, Riley's engineering prowess takes viewers inside the marvels of large-scale industry — and he shows what happens when things don't go as planned.
