Didnt see this before our group flight or we could have discussed about it.

The safety of Airbuses? or what is the spin? (or the lack of spin for what I see 'n the pic)

If we gave everybody in the World free software today, but we failed to teach them about the four freedoms, five years from now, would they still have it? Probably not, because if they don’t recognise their freedoms, they’ll let their freedoms fall

I think this is more about engine manufacturers than aircraft manufacturers. Lately quite a few uncontained failures happened. That is rather surprising, because in the good old days engines were tested if all the parts stayed in the casing, when they broke the scoops with firing chicken in them at full throttle.

Kind regards, Vincent

Is AF using GE engines? We know for a fact that RR did test the engines from breaking the outer casing. Not too sure about GE, I'm gonna be assuming the same things too. However cases like this and the Qantas one made me think if these tests should include much more than what we can see.

It looks to me that the outer casing seemingly contained the explosion alright, seeing that there is no fragment puncture in the wing or fuselage (at least from what we gather in this news), but the whole thing simply fell off after that. Scary thought - the whole casing might hit the flight control bits on the way out and seriously screw up everything.

There are no GE engines, only the GP7200, which was derived from the GE90, and the PW4000, both very successful engines.

You're right. I confused it (engine-choice-wise) with the B777

I stared now for a while at those photos and I don't see anything that makes me think "explosion". The fan went off and took a part of the casing with it and honestly, I can't imagine any engine where the fan isn't able to rip of the inlet part of the casing, so that missing part of the casing is not so miraculous.
What makes me scratch my head is, why did the fan go on the first place? The way, the hub looks, it is as if the fan ripped off in one piece, it was not really disintegration, like the blades flew of one by one. That would look much more like shotgun on the wing above it. And it doesn't look like someone shot a frozen goose or something in it, then there would be at least some discrete impacts from fan blade parts visible. But the casing is all around gone in the front part, that means, the fan didn't just suddenly flew away in some direction but almost as if it wobbled some few times around before it flew off. So, maybe a material problem? Or some maintenance problem that compromised hub or fan axis?

That's what I meant by 'explosion'. :D Basically one or more blades flying off into the casing - a sudden high energy event. The shrapnel, if any seemed contained well.. the casing not taking any flight controls or flaps out is a good thing.

I'd imagine that it's something to do with what holds the fan and the rest of the engine together, or what connects them... a drive shaft or something. I mean, that's kind of what it sounds like, if the shaft cracked, the fan would go out the front breaking the connections?
