...a few minutes on Google suggests that biologists have by now worked out a few plausible ways in which a bacterial flagellum might have evolved. This seems reasonable to me; I assume that the biologists are competent and know their field.
I don't know of any examples of detailed predictions of the future where the 1) it is clearly established that the prediction was actually made before the thing happened; 2) it is clearly established that the thing happened as stated; 3) the thing has a substantial degree of unknowable detail.
...I can think of a few biblical examples, but given the length of time between then and now (and how much even recent eyewitness accounts can be distorted) I can also see how all those examples would probably fail on point (2) at the very least. (I think I can probably find examples that pass on points (1) and (3), at least).
Ok. But one of the main reasons biologists have considered the flagellum issue is because Behe proposed it as something that couldn't have evolved. So the point of that was that since there are basically an unlimited number of things in nature, many of them won't have been considered in detail by scientists, or at least we might not be able to personally find those considerations (if they are only available in some obscure academic journal, for example). So if I take some animal or some organ, check to see if anyone has found a plausible way that it could ...
