Interdimensional, a starship trilogy

"Should we maybe say our goodbyes chief administrator Rasplos, before we leave?", captain Lucinda proposed good humouredly as the starship lifted from the ocean. 


"That's not necessary, I think he 'll understand", said captain Lucinda. 


"I was only joking", chuckled captain Lucinda. 


"We were not even supposed to have been on the planet", said captain Maguire. We just got caught up in a situation. 


"Pilot, set direct course for Earth", captain ordered lieutenant Tashinga at flight control. It felt good to say the words and for good measure he added, "Maximum speed if you please".
