No flap landing: Giving the pilots the benefit of doubt, maybe they were concerned about low fuel and wanted less drag or a different deck angle to avoid seeing the fuel pickup becoming uncovered. Or .. the extra speed afforded more speed and thus greater rudder authority that he felt was needed. If any of this were the case, his decision was using his emergency authority. I have no way to know without talking to the Captain. Just trying to give some credit until we know otherwise.
