The cast put on the brakes long enough to spill their guts about all the jaw-dropping makes and laughter-inducing misfires from their risk-fuelled second season: piloting a rocket-powered tricycle, walking chute-less on the wing of a biplane, back-flipping a 75-foot gap across two buildings 130 feet high, and nearly drowning in a foam pit after a 65-foot fall. Whether a stunt ends in epic pass or epic fail, the Nitro crew never gives up and never gives in.
