'Swarm' by Phil Ford

A USAAF transport plane is detected on a collision course with Skybase; Colonel White orders the Angels on intercept launch, and when the plane fails to respond to hails, Destiny shoots it down. However, the explosion unleashes a swarm of green insects, which immediately cover Destiny’s Interceptor; the bugs enter the plane through its engine intake, and immediately begin to disrupt its systems. With her craft out of control, Destiny launches her escape pod, but the creatures cling to its hull and begin eating through the metal in order to reach her inside. Realising that she cannot land on Skybase, Destiny decides to eject, only to learn that the bugs have damaged her parachute. Captain Scarlet instructs her to eject anyway, and then skydives off the Skybase landing platform after her; just in time he reaches Destiny and activates his own chute, landing them both safely. Later, Colonel White informs his staff that the transport plane contained a consignment of experimental cyber bugs, which had been taken over by the Mysterons. Believing the threat to be over, Destiny returns to her quarters, unaware that a solitary bug has secreted itself on her jumpsuit. It isn’t long before the creature reproduces itself, creating a massive swarm that quickly infects Skybase’s systems; the creatures then capture the sleeping form of Lieutenant Green, tapping into her brain in order to learn the location of Skybase’s atomic reactor…
