Thank you Indian_flyboy!!

But I would like to have the article similar to the quotation from Captain Haynes in the thread "DC-10: The Relation Between Ailerons And Gear"

Anyone could do me a favor?

There were passengers on a United 727 taking off from Sioux City. Imagine there reaction when they saw a United DC-10 burning on the ground. Knowing how most people don't know that much about aviation, they probably thought that the DC-10 was a 727 and that they were gonna crash.

McDonnell Douglas engineers poorly designed the DC-10's 3 hydraulic systems by putting them all together side by side instead of having them separate from each other so that in case one of the systems gets ruptured the other 2 can take over keeping the aircraft controllable. The DC-10 at the time of the UA Flt 232 accident, lacked one way shut off valves in the hydraulic lines to contain any leaks so as not to have a total loss of fluid.

Dear TEDSKI -
You think they put the lines separately in 747s (for the 4 systems...?)
xxx
Nope -
And that was the reason JAL 123 went down... at least UA crew did save many people lives by attempting to control the aircraft, and landing it at Sioux City... with the JAL plane, they did not...
xxx
What can happen to a DC-10 can happen (again) - including 747s and many other "all hydraulic airplanes"... at least in the Caravelle and the Comet, which are mid-1950 designs, if the 4 hydraulic systems were lost, they could go through the floor of the cabin to the reservoirs, and fill them with Coca Cola, strained tea, water or milk - in emergency...

They dont say if milk must be low fat...  Wink/being sarcastic

747skipper, I read that Boeing installed the one way shut off valves to the 4 hydraulic lines on the 747 as well to prevent what happened to JAL 123. When the DC-10 & 747 were designed why didn't they separate the hydraulic systems from each other in different areas of the aircraft?

Yes did they did fix the problem supposedly... I hope, we all hope...
Both the DC-10 and the 747...
xxx
But let's face it, all designs remain faulty to some points... The 4 hydraulic lines in the tail (for 747) are still needed to move rudder and elevator... and while I know "only 1 system left" could do the job... still...
xxx
No matter what accident, which is an aircraft system (or structural) failure, the engineers scratch their head for solutions... That poor DC-10 had horrible incidents and accidents (floor collapsing because belly door), then there was the Chicago tragedy (engine fell-off, then leading endge retracted) - yet at times airplanes survive incredible catastrophic failures, some, bomb explosions.
Then if it is not that... airplanes collide...
