Corrected entry: When Rico is whipped, the guy with the whip is shown about 15 feet in the background. The lashes leave huge 18-inch stripes on Rico's back, implying that the whip is about 17 feet long. But the maximum effective striking length of a whip is only 12 feet, at most.
Corrected entry: The Federation is in conflict with the Bugs and mention is made early on that they throw asteroids our way. Yet, an asteroid manages to "sneak up" on Buenos Aires. One would think that they would be on the look out for such things. We have even see them destroy one. Yet, B.A. gets zero warning. An asteroid could sneak through if it were accelerated to near light speed. But in that case an asteroid equivalent to the mass of the asteroids we are shown would pretty much vaporize the Earth.
