He (correctly) reasoned that if he could put any fluid at all into the reservoir (which can be reached from inside the airplane) that would at least allow him to get the gear down, and that a new gear hydraulic system was cheaper than a new airplane. The only fluid handy happened to be in his bladder, but that did it.
