Destruction of adjacent structures, namely the inlet section, which is not intended to contain anything. I think the engine casing held. The picture I'm getting is that a fan blade departed, the debris got thrown forward into the undefended inlet section, the inlet section was damaged and then aerodynamic forces and vibration caused it to fail, throwing debris and causing damage to the leading edge and window, causing the decompression and subsequent blow-out of the window. This is why I speculate that the decompression did not occur immediately, and explains why the pilot did not report decompression, declare emergency or initiate an emergency descent. I think her original transmission of "descending" may have been due to the engine failure alone and inability to maintain RVSM altitude. The delay between the engine event and the decompression event is something I guess we have to wait for...
