It would have been nice to go up through the opening in that overhead hatch and have the shuttle meet us there like the humans had done before, but (a) the armed shuttle was still in play somewhere and there was an unknown chance it would be out looking for our shuttle; and (b) we didn’t have ART-drone with us so it could carry the humans up to the unresponsive hatch. (That was such a big "but" it should probably have been (a) instead of (b).) Our shuttle could land or hover to let ART-drone out, but it would have to come all the way down here to get the humans and that was more time on the ground, more time for the B-E shuttle to find us.
