Metalcrafters is right by claiming that the contract was discharged. The text makes a list of the impossibilities that allow for a contract to be discharged. "That the occurrence made performance impossible. The doctrine of impossibility relieves nonperformance only in extreme circumstances" (Twomey & Jennings). Samet's death in the automobile accident qualifies Metalcrafters for the doctrine of impossibility. He was the only one capable of making the product and died unexpectedly.
