Any ideas yet what was the reason?

Compressor disk faillure.
http://avherald.com/h?article=49ffa115&opt=0Full disk faillure is a category more serious than just loosing a fan blade. This is of the type DC-10 at Sioux City.
Btw, recent uncontained engine faillures are mostly General Electric engines. Remenber the BA 777 at Las Vegas? My estimate is that 90% of the uncontained engine faillures lately are General Electric. Maybe a good idea next time you fly to not only choose the airline, but also the engine manufacturer.
Kind regards, Vincent

How so, many planes are available with different engine options, so as passenger, yousee what you get only before you board, if at all (in some airports, there aren't even clear windows anymore to see the plane at the jetway.

Fairly rare failure, but it does raise concern, this has happenned about 3 times already in what - 6 years ? Granted that Qantas one was a RR engine, but if 2 manufacturers has had this problem then it may happen again.
Whereas the Sioux City one was probably the only a few in decades and that was due to some maintenance thing (iirc?). I don't recall that kind of stuff happening again all the way up to the late 90s. Although there was one where a Lockheed Trident had a similar failure but that was due to the pilots fooling around with the throttle settings causing it to vibrate uncontrollably and disintegrate.

The DC-10 (MD-10) which burned, had General Electric engines. The 767 American had GE engiens.
Doesn't BA use RR and IAE engines only?

BA may have loads of RR's, but the few GE's they have are the ones exploding.

With Pratty & Whitney now testing engines with a geared turbofan in them (additional point of failure), and I know that they will try to increase reliability to it as much as possible, but, at the end of the day it's still an additional point of failure... at what point will the gears fail and cause a possible uncontrollable rotational speed (if this is even possible to begin with, as I am still trying to get a handle on that concept)?
