Everything is done via checklists. You don't just "try a few more times" unless there's some indication that you should. They only had 30 minutes of fuel left, and if they had an unrelated go-around and ran out of fuel while setting up for another landing, everyone dies. Once you've run all the relevant checklists and ARFF is in position, you land the plane.
