The Jews were probably to blame too.

The engines were serviced wrong no doubt, but a single engine serviced all electronics (in this case it was the engine they lost)which was definitely a design flaw. Because of that the crew didn't know of the stall. Even in single engine failure, that thing should have been able to land with minimal injuries at that height/speed.

Having the electronics serviced by a single engine would be a problem today in an era where airplanes are engineered to have multiple back-ups. With 2nd generation jetliners, it would be more of the norm. The contemporary L-1011 (which was a commercial failure) was really the only 2nd generation jetliner to be built with multiple back-up systems. It's kind of a shame the Lockheed wide body didn't do better as it was revolutionary in many ways.

Another flaw with the DC-10 though is that the hydraulics all ran through 1 section so if a failure would cut 1 line, it would also cut all 3 lines. This happened with 191 and it happened with United 232. Even if the DC-10 kept its electrical power, the lack of hydraulics would've killed them before they ever could land, and unlike 232, with no left engine, there was no way to control via asymmetrical thrust even if they could climb out.

EDIT: I should also add that the DC-10 had an APU so the loss of electrical power if an engine went wasn't as much of a concern since the APU would restore power to the systems. Loss of hydraulics though, as mentioned, ensured this plane would crash no matter what transpired once the engine broke free.

I remember walking home from Elk Grove HS and just seeing smoke in the distance. The magnitude of what happened took awhile to set in. We were accustomed to having the planes as background (pausing on the phone as they took off), but I grew up a bit faster on that day. I remember my chemistry teacher bemoaning the tv coverage because the reporter had never heard of "metal fatigue".

Just starting this, don't know enough to recommend but-

That crash literally killed McDonnell Douglas, which at the time was up there with Boeing.

The DC-10's reputation never recovered and it took its company with it. The DC-10 was a flawed airplane, but this crash was ultimately the result of American Airlines failing to follow the proper steps on engine replacement rather than a flaw with the aircraft.


My grandfather was a manager at the Long Beach plant where they were built. He took me thru there when I was about 6...the place was massive. That was the only company he ever worked for...he started at Douglas before the war. After Pearl Harbor he enlisted in the Air Corps but Douglas listed him as essential to the war effort so he had to come back. I remember him and dad talking about the accident...this would have been about 1988 or so. He retired in 1986. I didn't usually pay too much attention to their conversations but a conversation about a plane crash killing hundreds of people caught my attention. I was only 10 so I didn't know anything about the accident. I do remember him telling dad that the airline was trying to save time servicing the engines and they weren't following the proper procedure. He said they were even noting in their service logs that they were having trouble re-installing the engines after servicing. I wish I could remember...were they removing just the engine when they were supposed to remove the engine and the mount? I think they were just removing the engine and then damaging the mount when they were re-installing it. I can't remember...that was quite some time ago.

The L-1011 was an amazing plane. That should have had a longer career and instead the DC-10 family won out.

Have any of you been to the 191 memorial? It's in the park at Touhy and Lee - along Touhy. I realize an elementary school class (or was it a junior high class) put the thing together, but to me a memorial needs to be at the actual crash site.
