Interesting random fact about this crash. On board was a man by the name of John Stille. He had invented a very versatile carbon-carbon bond formation that bears his name “the Stille reaction”.<p>His work eventually resulted in a Nobel prize for the scientists who built upon it.<p>He didn’t survive the crash.<p><a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;John_Kenneth_Stille" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;John_Kenneth_Stille</a>

Air Crash Investigation&#x2F;Mayday does a pretty good dramatization of this flight:<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=N-UM-YcwWBc" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=N-UM-YcwWBc</a><p>A similar incident took place in 2003 on a DHL cargo plane after being hit by a surface-to-air missile. Miraculously they did manage to land the plane intact despite the total loss of hydraulics and needing to rely on engine thrust alone to control the plane.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;2003_Baghdad_DHL_attempted_shootdown_incident" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;2003_Baghdad_DHL_attempted_sho...</a><p>The Mayday episode might also mention (least from my memory of last watching it) an experimental NASA program developed sometime after this crash that would allow &quot;full airplane control&quot; via computer in the event one more more control surfaces could not be used. It achieved this by translating normal flight inputs into sophisticated throttle manipulation of the engines, just like the pilots on flight 232 did, but with the reflexes and modeling of a computer.<p><a href="https:&#x2F;&#x2F;www.nasa.gov&#x2F;centers&#x2F;dryden&#x2F;pdf&#x2F;88794main_PCA.pdf" rel="nofollow">https:&#x2F;&#x2F;www.nasa.gov&#x2F;centers&#x2F;dryden&#x2F;pdf&#x2F;88794main_PCA.pdf</a>

With all the attention given to the 737 MAX lately, it&#x27;s easy to forget that airline travel is dramatically safer today than it was just 30 years ago when this incident took place.<p>Fatalities per revenue passenger-mile have decreased by a factor of 15x from 1989 to 2018 (and 54x from 1970 to 2018) [1].<p>[1] <a href="https:&#x2F;&#x2F;theblogbyjavier.com&#x2F;2019&#x2F;01&#x2F;02&#x2F;aviation-safety-evolution-2018-update&#x2F;" rel="nofollow">https:&#x2F;&#x2F;theblogbyjavier.com&#x2F;2019&#x2F;01&#x2F;02&#x2F;aviation-safety-evolu...</a>

&quot;A fireball and smoke rose from the middle portion of the plane as banks of seats began vaulting and somersaulting high above the flames. Some of the banks of seats were thrown far above the fuselage in great parabolas, shot as if from a cannon by the centrifugal force of the aft end of the fuselage swinging in its majestic, flaming arc. What must it have been like to take that ride, alive, aloft, alone, aware, unhurt as yet, and looking down on the green earth?&quot;<p>Holy shit.

It was a grim situation, but I don&#x27;t think the end of the article does justice to the fact that nearly two-thirds of the passengers survived what by all rights should have been completely unsurvivable, thanks to the sterling performance of the flight crew and the flight instructor, as well as the flight attendants for keeping everyone calm and prepared, and the control tower personnel for getting a prodigious amount of local firefighters and EMTs on the scene before the plane arrived.<p>It was, as Wikipedia dryly puts it, &quot;a prime example of successful crew resource management,&quot; and had a big influence on training practices as airlines sought to replicate that professionalism.<p>United Flight 232 was an engineering disaster, but a piloting miracle.

I heard Al Haynes speak in a small group setting regarding this incident when I was in aviation college.<p>The amount of composure they had to maintain to even get this aircraft near an airport was unbelievable.

I notice that the flight instructor disobeys the captain, who says to says to remove power from the engines, and does the opposite right as they&#x27;re touching down.<p>Was there ever any thought as to whether that contributed to the loss of life?

This is one of those classic aviation tales I&#x27;m never not going to re-read when they pop up, right there with the Gimli Glider [1] and the various SR-71 stories.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Gimli_Glider" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Gimli_Glider</a>

I wonder if the same McDonnell Douglas corporate culture behind the flawed DC 10 is what led to the MAX? It&#x27;s often said Boeing&#x27;s acquisition of Douglas was more of a reverse takeover.<p>On a side note, I once met an aircraft investigator who called it the Death Cruiser 10, and that it put his kids through college!

One thing I never understood as a kid, was why wasn&#x27;t there better footage of a crash. Many people at the airport knew the plane was coming in, and they had plenty of time. Yes this wasn&#x27;t 2019 where everyone has a camera in their pocket, but nonetheless I always thought the could have done better than the crazy shot through the chain-link fence.

IIRC, several policy changes resulted from this crash:<p>- Pathway lighting for exits<p>- Reminding passengers that the nearest exit may be behind you (not all airlines remind you)<p>- Changes in how lap children are dealt with during an emergency.

This book about the incident is a great read. <a href="https:&#x2F;&#x2F;www.amazon.co.uk&#x2F;Flight-232-Story-Disaster-Survival&#x2F;dp&#x2F;0393240029" rel="nofollow">https:&#x2F;&#x2F;www.amazon.co.uk&#x2F;Flight-232-Story-Disaster-Survival&#x2F;...</a><p>It goes into detail about the causes of the crash, the stories of the passengers before and after the crash.

I also remember something about Sioux City itself - the hospital was at shift change, so they were able to have just about 2x the normal amount of staff available.<p>They had enough advance warning and were able to start getting more fire&#x2F;EMS resources heading that way as well.

111 people died on that flight according to Wikipedia, more amazingly, 185 survived.

Would ditching (assuming there was a large body of water near) or landing in a huge cornfield (like Ural Airlines 178 out of ZIA (Moscow-Zhukovsky)) have made it better or worse?

Did the kids without seatbelts all die? I can&#x27;t imagine what I would do as a parent of one of those babies if I were told to put them on the ground. Like... Hell no!

Note that this <i>article</i> is from 2017, but the <i>crash-landing</i> was in 1989.

so back in the day we had to watch film footage of this as part of the training for working on Boeing aircraft electrical wirings.

I&#x27;d never read about this flight before. Thanks for the share. Tragic about the loss of life.

&quot;When the plane pancaked onto the runway, more than 10,000 pounds of kerosene came out all at once from the ruptured right wing and turned to mist.&quot;<p>I wonder why they didn&#x27;t &quot;dump the fuel&quot; just before the crash to have avoided the fire. I thought this was standard operating procedure to dump fuel before crash landings.<p>I had read about the crash awhile ago and as I recall many people that died died of smoke inhalation from the fire and not the impact itself.
