<<Well, it could be that, or it could have been something a "tad" more interesting like an inflight thrust reverser deployment of an IAE V2500...?>>
Why on Earth would it be something like an inadvertent inflight thrust reverser deployment. Nous sommes trying to be un peu dramatic ici, peut-etre? That would cause major repercussions in the aviation business that you would have heard about by now!
When a twin has a serious engine problem or shuts one down, the standing instruction is 'land at the nearest suitable airfield'. I guess that would be the reason if 'engine problem' was confirmed. Let's not overdo the drama.
