Yes, only a small proportion of the world's 777 fleet is affected (most 777s have General Electric or Rolls-Royce engines, rather than Pratt & Whitney).

The bits that fell off have nothing to do with turbine containment.
When a turbine blade or disk lets go (which didn't happen here) nothing on earth is going to contain it.
Why during those eight years? What were you up to?

Just heard a report on CNN saying that a turbine blade broke and that took out a couple more
I'm not sure where the report originated - best thing is to wait until the experts have had a proper look - even if a blade did break there is then the question of why - did something go into the engine that shouldn't have
I guess it is only a matter of time before some idiot is flying a drone around and it gets too close and causes a problem like this - I know they are designed to cope with bird strikes but a metal drone might cause bigger problems!

I'm not an engineer but look at that picture i'd definately say something is not right 😂"I looked out...... I could see smoke coming... you just know something's wrong!"
Something of an understatement!

No, this picture shows the fan, not the turbine.

Is that one of those exploded views of an engine ?

I read an article which said that when Boeing took over Mc Donnel Douglas who were in a bad way that a lot of their managers took top jobs in Boeing which led to a decline in their safety standards.

That's when they must regret doing away with the flight engineer on board. Send him out there with some gaffer tape and a few zip ties and they would be fine to continue to Honolulu.

Not a view you see very often, but a good illustration of how light and well-engineered aircraft components are.
That cowl ring is around 11 feet in diameter (almost as wide as the fuselage of a 737) and yet it's partly supported by that flimsy tree branch:

The inconel/kevlar/tungsten carbide (combinations thereof, or delete as applicable) cover shroud is designed to do precisely that - blade failure containment. Have a browse on Pratt and Whitney's own website.
A lot of Boeing production was moved from Seattle to North Carolina (or South, I forget which) and concerns about lesser quality from that plant are well documented in the public domain - poorly fitted fasteners, incorrectly routed cabling, lots of little things adding up to a big bucket of creaks and rattles. Not enough to fail certification, but enough that these aircraft are difficult to sell once they're 5 or more years old. Be interesting to see where this one was constructed.

That statement is entirely correct.
But the Kevlar ring that you can see in the photo is in the plane of the fan, not the turbine. It appears to have done its job.
