Following the destruction of Fireflash 4, the International Rescue team take a more active interest in the next Fireflash test, Fireflash 5, as Scott joins Captain Hanson on the flight deck to co-pilot the aircraft, while Virgil stands by in Thunderbird 2. Almost as soon as the Fireflash takes off, Alan reports that its reported position is 20 miles off, and soon after, as with the previous planes, the elevator power unit fails and all power is lost.
The Fireflash goes into a crash-dive, but Scott has brought along a back-up radio system to keep in contact with Thunderbird 2 and 5. Gordon enters the airliner's starboard wing via a line from Thunderbird 2. There, he finds that the EPU wiring has been cut by a Saboteur, working for Benton Aircraft Espionage, who opens fire on him while attempting to escape. However, Gordon shoots him down and manually holds the EPU wiring in place, allowing the Fireflash to gain height and prevent another crash-landing into the sea.
