'Space City Special' by Dennis Spooner

Steve Zodiac is to receive the prestigious Astronaut of the Year award from General Rossiter. Learning that the General and Venus will be flying to Space City in a supersonic airliner, a devious Subterrain kidnaps the pilot, Major Todd, and brainwashes him to crash the aircraft once it reaches a height of eighty-thousand feet. However, when Venus and the General notice Todd behaving strangely, Venus takes over the controls – and only Steve can radio instructions to Venus so that she can land the plane safely…
