As pointed out in the answer to What items are shown in this panel of All-Star Superman?, Superman in the All Star Superman series has the space shuttle Columbia in his Fortress of Solitude. This seems really strange to me given that the comic was made in 2005, two years after the ship was destroyed in real life.
Why does Superman have it? Did Columbia not get destroyed in the comics? Did he put all the pieces back together? Is it from an alternate universe? And why is Superman allowed to keep it rather than letting it stay with NASA?
