Victory might also be wearing a space suit. Which... I mean, if I was flying into a combat zone, I would.... There should at least be one on the shuttle that they can put on, at any rate, if they are still both alive and conscious, and the shuttle isn't already completely decompressed after the crash.
Part of Tsuguka's orders was that she knew the vessel was already venting atmosphere, being as it was previously shot full of holes... But yeah. Teleporting directly inside the Eucharis would also be bad, unless there is a pre-depressurized airlock free.
As for the Mindy's actual carrying capacity, yeah, it's merely based on weight. The damage to exposed organic tissue seems to result more from explosively rapid changes in the density of the air around them. I would say a suit should be fine.
