@ Thrusty, Feathers, and others who are discussing the pic of the recovered disk in post #682:
You are aware that the poster has INVERTED the colors of that image as described, and as per instructions of post #629, and that the dark marks are thus actually bright marks in reality?
The round star shaped thing anyways is with 99% certainty the boundary of a reflection of a bright window to the right of the image. You can even see the outline from a part of the cart handle...
@topbunk: Just to clarify: I daresay most people would expect the generator of the affected engine to be gone (possibly literally :-) )- the fact that it is specifically mentioned does not by any chance mean another generator was lost for some reason?!
Darn scary list, either way!!
