Bombs that drop under gravity, in space.
I'm not sure how that's anything new to comment on seeing as how Y-Wings have done the same in other SW films.
This has come up so often in discussions of this film around the internet that it's almost like someone coordinated such an effort, ignoring this issue in other films in the franchise.
The only time I can recall ever seeing a Y-wing dropping bombs was when they were attacking the planetary gateway in the big battle at the end of Rogue One. Technically, they were in space, but it also looked to be a geostationary planetary low-owbit, so there would definitely be gravity. Now, if the gateway were orbiting the planet, that would be a different matter, but this was not the case.
To me, the "drop the bombs" scenes in E8
stuck out like such a sore thumb, I couldn't stop thinking about it for days afterwards. We can believe in artificial gravity on ships, just about. It's harder to believe when the bombs continue to accelerate towards their target long after they've left the bay doors.
I could have let it slide if they were powered or had thusters or something, but no; They just dropped, in space, far above the planet. If the bombs from ship A fell under gravity onto ship B, why on earth did ships A and B not fall under gravity down to the planet?!
