Yes the fan blades used to detach (perhaps not as many as we thought). Quite spectacular! And of course you will know how many miles of well used glider launching cable and old cable knots were put on the dump on a regular basis after the daily inspection of the cables.
I will be surprised if they find anything interesting after all these years - especially with you (and others from 615) already having carried out a multitude of searches.
