pretty much what I said, the blade was sent to an cheap, fly by night, independent contractor for refurbish, the necessary inspections and work were not done, and the blade returned to service, of course when you drag it into the court room, fingers are going to be pointed at everyone that can conceivably be implicated, I'm sure the plaintiffs tried to assign guilt on the estates of Wilbur and Orville
ETA: the loss of all hydraulic systems, and subsequent hull loss, due to a relatively minor mechanical malfunction, was especially tragic because a similar crash is May, '79 of American flight 191, where the #1 engine failed/separated, going over the wing shortly after rotation, the hydraulic lines were severed ,causing the slats on the left wing to retract and the aircraft rolled 112 degrees at low altitude and crashed, the engine out profile was nailed, which unfortunately reduced the already minimal chance of recovery, these design flaws were eventually corrected and the DC-10 became an awesome airplane after the loss of a few hundred lives, there was one more similar crash for pretty much the same reason, but essentially same story, small malfunction, loss of hydraulics, airplane unflyable, people die

Makes you wonder if it was done to help keep people calm more than anything due to the unclear air.
Its interesting because the last flight I had I wondered how often does those emergency oxygen dispensers get used.
The cabin crew deployed them so that the pax wouldn't inhale smoke. The crew had to manually deploy since they are only designed to automatically drop when there is a change in cabin pressure.
Not very often thankfully, and you have about 30 minutes of oxygen in reserve.

Well there was some back and forth on if it was actually smoke rather than pressure induced water vapor condensation, so I wanted to try to steer clear of that.

Not trying to get in a pissing match but but not the same thing.
Blade didnt fail. Fan disc failed. Big difference
We are talking about United 232, the Sioux City,Iowa crash, correct?
The uncontained manner in which the engine failed resulted in high-speed shrapnel being hurled from the engine; this shrapnel penetrated the hydraulic lines of all three independent hydraulic systems on board the aircraft, which rapidly lost their hydraulic fluid. As the flight controls on the DC-10 are hydraulically powered, the flight crew lost their ability to operate nearly all of them. Despite these losses, the crew were able to attain and then maintain limited control by using the only systems still workable: the two remaining engines. By utilizing each engine independently, the crew made rough steering adjustments, and by using the engines together they were able to roughly adjust altitude. The crew guided the crippled jet to Sioux Gateway Airport and lined it up for landing on one of the runways. Without the use of flaps and slats, they were unable to slow down for landing, and were forced to attempt landing at a very high airspeed. The aircraft also landed at an extremely high rate of descent due to the inability to flare (reduce the rate of descent prior to touch down by increasing pitch). As a result, upon touchdown the aircraft broke apart, rolled over and caught fire. The largest section came to rest in a cornfield next to the runway. Despite the ferocity of the accident, 185 (62.5%) passengers and crew survived due to multiple factors including the relatively controlled manner of the crash and the early notification of emergency services.[1]
The cause of the engine failure was traced back to a manufacturing defect in the fan disk, which had microscopic cracks due to impurities. The cracking was present during maintenance inspections and should have been detected by maintenance personnel, revealing shortcomings in the maintenance processes.

That is exactly why I load up on Xanax before every flight

me either, but you and I are really starting to whiz over semantics, condition initiated by a relatively benign cause, blade or disc, part of the same component failed, severing the three hydraulic lines, basically rendering the plane uncontrollable, lives were saved by the incredible ad libbing of some pretty good pilots, the plane was in an a death spiral until they started messing with the thrust, easy for me to say but I think if the power were reduced separately instead of simultaneously right before impact, it might have saved a few more, but it's crazy to Monday morning qb something like that, I've seen that scenario replicated in the sim a few times, and even knowing it's coming it's ugly, I salute those guys every time I think about it

This dude must have bowling balls in his pants to have the presence of mind to record this.

you can still fly on just one engine.

I just realized that I was referring to the entire rotor assembly, or fan, as a blade in my earlier posts, when you and I were actually talking about the same part, shorthand from work I guess, thanks

Wow, the envy I have for the people on that plane.
They should all experience the best day of their life after getting off that plane.
Hell I would've started on the plane...
"Umm stewardess, since it looks like we're all going to die in 10 minutes, how about you and me take a trip to poundtown and die in ecstasy"

People seem fairly calm. I was expecting Costanza-like panic.

wouldn't even need a perceived near death experience for that

I was in a situation kind of like this. I don't think it was as bad though. Maybe some of the pilots on here can chime in and tell me. But fwiw, I was calm and quite content.
My basic thought was. "I know the pilot can land this plane somehow, and we'll survive, and if not frick it, nothing I can do but try to go out happy."
On approach into Denver captain came on intercom and said we have landing gear failure, and will climb back up to altitude and make circles to burn jet fuel. Once enough fuel has burned out we will attempt a belly landing. If we try belly landing with the fuel on-board we may explode.
We burned fuel for like 45 minutes before they realized it was an instrumentation error, and got the gear down and landed the plane.
Me, my brother, and friends were calm and actually cutting up. My mom, their mom, and others were catatonic, b'c they popped so man xanax they didn't even know they were on a plane at that point. Some guy started handing them out like candy
