the World President – returns to duty to help lead the operation. Accompanied by the Angel fighter squadron, Scarlet and Captain Blue (voiced by Ed Bishop) depart Cloudbase in a Spectrum Passenger Jet and fly to London. Meanwhile, the Mysterons use their powers to create a massive systems failure on board an airliner, Flight DT-19, causing it to crash into the ocean and explode. A Mysteron reconstruction of the plane, devoid of crew and passengers, continues on the original flight path from New York to London. As a double of the Director General is driven in to London Airport in a decoy motorcade, the real Xian Yoh arrives in Spectrum's "Yellow Fox" – a secure transport disguised as an aircraft fuel tanker – and discreetly boards his private jet. As DT-19 lands, Scarlet, watching the operation from the control tower with Blue, experiences a sudden nausea that he interprets as a warning that the Director General is in danger. At that moment, DT-19 breaks away from the terminal and rushes towards the jet. Ordering the jet to take off immediately, Scarlet and Blue intercept DT-19 in their Spectrum Pursuit Vehicle. The plane is unhindered by the Angels' airstrikes, and when the captains target its undercarriage with the SPV's rockets, the launch mechanism jams. Shouting down Blue's objections, Scarlet ejects him and rams DT-19's wheels, destroying them and bringing the plane to a crashing halt. He is fatally injured when the SPV collides with a radar bunker. Meanwhile, the jet takes off but hits one of DT-19's wings and crashes into a field, killing the Director General and everyone else on board. As Scarlet's body is taken away in an ambulance, the airport chief assumes that he is dead, to which Blue replies: "Maybe he didn't die ... in vain." Production In Tony Barwick's script, the DT-19 co-pilot is called Johnson. Dialogue in the episode indicates that it is set on 10 July, the same day as the events of "Treble Cross" and the closing scene of "Flight to Atlantica". Barwick was fond of inserting references to 10 July as that was his birthday. The scale model of the entrance to London International Airport was designed by special effects assistant Mike Trim. "Winged Assassin" is the first episode of Captain Scarlet to feature contributions from uncredited voice actor Neil McCallum, who also voiced guest characters in the episodes "Big Ben Strikes
