Alice Averlong🏳️⚧️more sci-fi should deal with the fact that your average Enterprise starship has a fuel tank measured in Chicxulubs of antimatter
"a spaceship crashed" shouldn't be a bunch of wreckage in a forest and plucky scavengers finding neat bits of technology to resell, it should be a "so the dominant species on that planet has been forever changed"
even if it blows up in orbit, that's still 90 teratons of TNT going off. That's equivalent to a solar flare.
You're still going to Have A Bad Day.
oh, to clarify, when I say "Chicxulubs of antimatter", I don't mean, like, the amount of antimatter is equivalent to the mass of the Chicxulub asteroid: I mean the amount of antimatter has energy approximately equal to the impact at Chicxulub that extincted the dinosaurs.
that's the thing with antimatter FTL starships: they're super dangerous in multiple ways, and that's an inherent part of how they work.
even ignoring them potentially being armed, even ignoring that they can go very fast (and what happens when they crash into something?), just the power they'd need to store to be able to do all that makes them weapons of mass destruction on a scale we can't even conceive of

@foone I haven't seen it in decades-ish, but I recalled the Han Solo quote: "Traveling through hyperspace ain't like dusting crops, farm boy. Without precise calculations, we could fly right through a star, or bounce too close to a supernova, and that'd end your trip real quick, wouldn't it?"
(Yes, mixing fandoms, but it's an applicable point regarding FTL travel.)
