An enemy agent sabotages the test flight of the new Orbital Glide Transport, causing the craft to crash onto the launch control building. The flight controller is trapped inside, along with some vital monitoring equipment, and both will be destroyed if the Transport’s rocket fuel ignites. Joe takes on the brain patterns of two experts – in computers and demolitions – in order to save the day...
