Is it me, or are the major pieces of the Space Shuttle Still missing. I have heard nothing about the discovery of pieces of the three main engines, two Orbital maneuvering Engines, or three auxiliary Power Units. These are large, heavy, metal forgings out of temperature resistant material that should have survived the re-entry largely intact. Is it true that none of these have been found yet, and if so where are they. Could the entire aft section be in Toledo Band Reservoir?
