Can we assume that all Captains have their own Bison? Well, except Blue of course. His is probably a smouldering wreck embedded in the wall of some building
I liked the story on this one, once again it always hints at something much more obvious before surprising you, in this case a planned attack on Earth while Spectrum was focusing on the Moon. Serena's character seemed odd for some reason though. I guess it's just the last time we saw her off duty she was trapped in a cacoon.
Once major error I noticed though. Mars is 80,000,000 km from Earth, and in Rat Trap it stated Spectrum craft take 2 weeks to reach it. However, they clearly use the same craft to reach the Moon, which White says takes 24 hours. However the moon is only 384,403 km from Earth, which would of taken just over 90 minutes presuming a constant speed, and even if you factor in things such as acceleration and take off speed it's still way out.
