Troy's Jetpack Invention and Testing

Troy visits Garrett with a jetpack invention intended for use on skis. Garrett helps Troy understand the physics and potential dangers, including the risk of fire and injury. They simulate a malfunction using a mannequin, demonstrating the risks. Despite the dangers, Troy is determined to proceed. He later tests the jetpack in the Nevada mountains, successfully using it with skis, though the risks remain evident.
