Weightlessness was a condition any sci-fi pilot could experience without warning and your chances of staying alive depended very much on how you could cope in such an environment. This is why the SSRB (Space Safety and Regularity Board) deemed that any pilot wishing to hold a permit to fly needed to pass a yearly check. Such a regulation ensured that Zero G training spheres had a steady stream of occupants. Caoimhe and Turlough spent as they could working out in a sphere and when they were on form they moved with such ease that it had all the signs of a choreographed dance routine. Each would call a number or a name which conveyed the next manoeuvre to be performed. As such there was no set routine just a series of random manoeuvres in response to the action called. The idea being that little warning was given to any movement making the response as unpredictable as any real emergency.
