Determined to acquire the secrets of International Rescue's "Thunderbird" machines, the Hood plots to engineer a rescue situation that will give him the perfect opportunity to spy on the organisation. Travelling to London International Airport, he plants a bomb within the hydraulics of "Fireflash", a new atomic-powered hypersonic airliner departing for its maiden flight. Its passengers include Kyrano's daughter Tin-Tin (voiced by Christine Finn). After "Fireflash" takes off, the Hood anonymously calls air traffic control to reveal his sabotage, warning Commander Norman that the bomb will detonate from the impact of landing.
