OK, this claim of "never had a problem" reminds of a very recent show on Smithsonian Channel about Air Disasters. In 1989, United Airlines flight 232 suffered a SINGLE middle engine failure of the turbofan blade (made of titanium, BTW) which severed ALL 3 of the airplane's hydraulic systems. The DC-10 has a TRIPLE REDUNDANT system that is professionally designed and maintained by the best crews in the world. The resulting crash ONLY killed about half of the passengers due to heroic efforts by the flight crew to defeat the phugoid curve induced oscillation. See for details:http://en.wikipedia.org/wiki/Phugoid

My point is that this DC-10 had triple redundant HYDRAULIC system. The BTV is a single point of failure HYDRAULIC system. One can claim that they've never had a problem UNTIL YOU DO. At least with a double redundant system, the odds are pushed further down that your "problem" will occur and kill you.
