Spoilers Star Trek Beyond: Errors, Goofs, Inconsistencies

[Crazy Eddie]

Did anyone else find it off that Kirk and Chekov were able to shoot through the glass on the bridge so easily. I would hate to see what would happen to the bridge if they took a direct hit from a full sized ship.

Why were the last 3 swarm ships stopped by the Franklin. We saw that those ships could bore through the likely tougher armor of the Enterprise with easy.

Not moving fast enough. Atmospheric drag, plus they weren't moving at ramming speed, plus a couple hundred tons of water getting splashed up in front of them.

Also, the swarmships didn't really penetrate more than one layer of Enterprise hull - cutting through the neck took the concerted action of a great many of them. The three ships did pierce the outer hull of the Franklin, and Chekov reported those three breaching points, after which Kirk ordered a search for intruders at those specific locations - a logical step in light of what he knew about the behavior of the swarmships.

Or any of them. What, they run on chemical fuel now, while in the previous movie they failed to work when warp power was offline? Then again, if they do, they probably share a common fuel infrastructure, or else some thrusters would run out of fuel sooner than others, depending on maneuvers. So forcibly igniting one might light up the whole system.

These are once again "thrusters" of the exclusively ventral type, apparently designed for takeoff rather than steering. The Franklin has the same sort. Looks way more primitive than any takeoff system we have seen since they days of Cochrane. A backup to the backup that amazingly did not fail when Kirk took his ship out of the sea in the previous movie?

Well according to the TV shows, the RCS thrusters are hot gas propelled and fuelled by deuterium.

Unless they had some sort of fail safe that cuts off when main power is offline. Since they were seperated from the warp core (Kirk made the sequence complete) the power source may have switched over to their own back up to engage the thrusters. Obviously, in this instance, they really didn't have time to do any emergency maneuvers.

In other words, it's a chemical fuel back up that could be ignited if main power is disconnected or activated in emergencies.

I do agree with this point. Kirk's efforts to find the boarders makes perfect sense. The swarm ships seem to function better as a group, but single ones could only do so much.

There's your answer...they almost died due to that last time, so they had Scotty rig it up so that the thrusters could work without warp power online.
