The Boeing 777X And Its Unmatched Foldable Wings
An unusual scene may become commonplace at airports in a few years if Boeing succeeds in making a new system safe for commercial operation. (airlinerwatch.com) Más...Sort type: [Top] [Newest]
Chances of Airbus claiming this is an(other) example of US government subsidizing Boeing has to be high.......
The end of the story says new engine would be put on in Renton.
I think they mean Boeing Field or Everett. Not sure a 777 has ever landed or taken off from Renton.

Probably bringing up a previous post, but.
Two points.
The United States Navy,
Twenty years on and off of flight decks, and I never saw a failure of a folding wing in flight or even on the flight deck or ground.
Remember this minor point, a 777 will probably never pull the G’s that a F18, A6 or the now rolling out F35. If they do, folding wings will be the least of the aircrews concerns.

Small aircraft have different dynamics than large ones and I can guarantee you that military aircraft do not get the use of civilian aircraft
I had to kind of laugh when the probability of catastrophe was mentioned...that proof of no chance of catastrophic problem with these wings would have to be given. That's the same kind of thinking, at the time, that caused the claim that the Titanic was unsinkable and, also, that no jet could lose all hydraulics...'til flight 232 crash landed in Sioux City, Iowa, after that very thing happened, and why there was no mention of such a catastrophe (and action to be taken) in the flight manual (and why they had to keep repeating the problem to whomever took the call when they called it in to whatever entity/authority in (I believe) Minneapolis...cuz no one there believed such a thing could happen, either. It's a good reminder, I guess, to "never say never."
Right on, Linda-like the odds that Douglas engineers calculated were 10 billion to 1 that an engine would come off the wing of a DC-10, so it was ok to route the electrical and hydraulic system through the same area of the wing, thus giving us the American Flt 191 crash at O'Hare and 273 lives lost. "No possibility both systems would be inoperative."
the engine came off because of a faulty engine-change procedure American Airlines was doing.. not because of the design.. American was using an unapproved method of re-installing the engine with the pylon attached that caused cracks in the receptacle on the wing
If I recall correctly, I believe there was also a flaw (tiny impurity) in the material used to make that, too, which was missed.
...come to think of it...I think we're talking about two different things/accidents. Flight 232 had no engine come off. The engine in the tail of the plane actually blew apart due to the flaw/impurity in the metal used to make one of the fan blades, and when that flew apart, it severed all three hydraulic lines. I think I recall something about an improper procedure during maintenance of some engine on a plane involved in a crash, but I'm not sure it was concerning Flight 232.
yeah... Chicago.. improper engine installation.. rear coupling broke...engine rotated up over wing tearing out the hydraulics.. slats and flaps retracted... left wing stopped flying at that speed.... Iowa... middle/tail engine blew and took out the hydraulics...great save by older "seat of the pants" pilot...
Yep...Cpt. Haines. He did a great job. He was very good to the Sioux City area after that, always coming back to speak at this event and that. About a year or so ago, tho, he said no more cuz he had to relive the event every time he gave his speech about it. Can't blame the guy for wanting to put it to rest! Got to praise the Siouxland area, as well, with the great rescue effort they provided. I used to work (at the Le Mars Daily Sentinel) with the guy who drove the ambulance that took Cpt. Haines to the hospital after the crash. While lots of people wouldn't want to live in the Sioux City area (unless they were born there), thinking there isn't "enough to do there," it's a great place to crash land...great caring, capable people.
Flight 232 did have a design flaw, tho...in that no one contemplated the possibility of a fan blade's blowing apart could sever all three hydraulic lines, so stop gaps had to be put into place so not all hydraulic fluid would be lost in such an incident. Like I said, "Never say never."
