I'm curious to know what materials are and are not likely to be encrusted by coral. As an animal I'm sure that coral are choosy about what they will grow on (what ever the Ballard object is coral didn't seem to grow on it). The question could be are there any of those materials likely to be part of the Electra. I agree that a lot of the plane may have been encrusted to the point where it is no longer recognizable as a man-made object, but is that true for everything on the plane?
