After blowing up Travis' ship, Cally says, "You could hardly miss at that range." However, Cally was a lot closer to Blake in Time Squad, and she probably would have killed him if she felt he was a threat.
At least twice we see Liberator in a very stationary orbit. No movement at all. ;-)
If the Liberator is so fast, how do Travis and Servalan not only get here first, but get here early enough to establish themselves with the royal family?
And is there really only one royal family on the whole planet? And Blake and company sure are lucky they just happen to catch the right one. (Not to mention getting the verbal trigger from the old coot just as he dies of old age.)
