I'm not competent to judge, but from what I read on another website, two additional elements [1]. On the video of the bird strike flaps were deployed, but during the crash they weren't. The plane did a 180º and landed on a different runway than it was initially approaching (tailwind, making it worse).

This suggests (this is only speculation) a scenario akin to: normal approach for landing -> brid strike -> go around (retract flaps and full power on the remaining engine) -> loss of power on the second engine (so no more hydraulic power, and no power to climb) -> attempt to land in very unfavorable conditions.

As you say, give it a couple at least a day if not more to settle.

Can’t speak for Jeju, but at United flaps 5 is the go-around flap configuration. Never heard of flaps zero on a 737 for a go-around.
