All the Tracys are dedicated men of action, and Scott Tracy is no exception! The eldest of Jeff Tracy's sons, Scott pilots the rocket-reconnaissance aircraft, Thunderbird 1. First to arrive at any disaster scene, he evaluates the situation and coordinates the team's rescue strategy on site. Due to the importance of Thunderbird 1 to International Rescue's operation, Scott is present for nearly every rescue mission. Nonetheless, even Scott has his limitations, and in Action Alert, he stretches himself to those very limits. Can he do so without consequences to himself and International Rescue?
