Talking about priorities…
This beaten up ship was originally intended
as a short range transporter with a small crew.
So even if they would have “landed” without
loosing pressure they probably would only have
enough suits for 2 or 3 lucky dwarves.
And even that wouldn’t have saved em in the long run
IF there wasn’t any breathable atmosphere.
So literally just plummeting to the surface and hoping
for the best was as good a plan as there ever was.
