15 Infamous Movie Plot Holes (That Actually Aren't)
12. Why Aren't Kirk & Sulu Killed By Beaming In Mid-Air? - Star Trek
The "Plot Hole": After Kirk and Sulu attempt to escape the Romulan drilling platform, they're beamed back onto the Enterprise by Chekov while in free-fall. How come they weren't killed by the momentum of slamming down on the Enterprise's beaming pad?
Why It Actually Isn't: For starters, those who pay attention will hear Chekov say that he's "compensating for gravitational pull", a fairly ambiguous phrase that basically has them covered.
Furthermore, it's totally plausible that momentum is not reconstituted during the beaming process, completely cancelling it out and giving the two a safe landing when they're back on the Enterprise.
Do you really think technology that can teleport a human being across vast distances can't stop their momentum? Really!?
