JetA, I'm glad you clarified that, its just that too many people posting stuff like "the news said the weather was to blame" and your post did not come with any explanation.
...and I agree with your "lift-dump-explanation"; after posting the above, my boss and I talked about the same issue. It sounds like a valid scenario that they tried to go-around with the flaps down (I was told 90deg in lift dump position?!).
Mechanical: I actually became a victim of hear-say too... somebody told me the mechanic on the field has said, that he only heard one engine on the go-around - that why I mentioned it COULD be a mechanical too.
