The Egypt Air one was apparently diagnosed as being triggered by delamination of the carbon skin inside the air intake. As soon a little bit of the lining separated, the rest from the segment in question is sucked into the intake a bit like a girl's hair being sucked into a spa intake. The weakened nacelle segment then implodes as a result of the high negative pressure, followed by an engine fault caused by ingestion of all the carbon fibre reinforced plastic from the cowling structure.
Last night's incident and the photographic evidence certainly seem consistent with it being another example of that phenomenon. I wonder if wet conditions are a contributing factor in such cases?
