Winged Assassin - Plot

Plot

The Mysterons threaten to assassinate the Director General of the United Asian Republic, Xian Yoh, who is completing a tour of the United Kingdom. One night, a sniper targets the Director General in his London hotel room, only for Spectrum officer Captain Grey, acting as bodyguard, to shoot him dead. Maximum security is imposed at London International Airport, from which the Director General is due to leave Britain. On the permission of Colonel White, the Mysteron reconstruction of Captain Scarlet, who has assumed the consciousness of the deceased human agent and is now "indestructible", returns to official duties to lead the protection operation with Captain Blue. Elsewhere, the Mysterons engineer a power failure on airliner Delta-Tango 19, which plunges into the Atlantic Ocean with the deaths of all on board. An unmanned reconstruction of the plane continues on the original flight path from New York to London.

An impersonator Director General is driven to London Airport in a false motorcade. Meanwhile, the real Xian Yoh arrives in Yellow Fox, a secure Spectrum transporter with the appearance of a fuel tanker. When DT19 lands a short distance from the Director General's private jet, Scarlet experiences a sudden nausea which precedes the revelation to the Control Tower personnel that the airliner is a weapon: breaking off from the terminal building, it charges forward, threatening to crush the jet. Leaving the Control Tower in their Spectrum Pursuit Vehicle, Scarlet and Blue attempt to fire at DT19's undercarriage, but the projectile gun is jammed. Activating Blue's ejection seat, Scarlet rams the wheels and succeeds in halting the airliner, but then collides with a radar bunker, sustaining fatal injuries. Meanwhile, the jet lifts off but fails to gain sufficient altitude, clipping DT19's wing, crashing into a field and killing all including the Director General. Blue assures the airport chief that, despite Spectrum's defeat, Scarlet will return to face the Mysterons again.
