Al Haynes could have used this system in the DC10 ...
If Al Haynes had been in an L1011 instead of a DC-10, he would have had a
much better chance of landing the airplane in one piece...due to hydraulic fusing...built in at the factory, not added later on.
Face it folks, the 'ole TriStar was so far ahead of its time, it's unreal.
Speaking with a (now) retired Boeing design engineer a few months ago, he related that when Boeing looked at the L1011 years ago, they found the systems integration/redundancy so very good, it was a huge wake-up call to the folks in Seattle.
Lockheed, simply the finest, straight out of the factory, years ago.
PS: and yes, one can split the spoilers for pitch control, just like on the 707, years before.
A superb design.
