Saddlebags, not the kind that you put on a horse, or the kind that chocolate cream pie puts on you.
These are new saddlebags, more properly toolboxes, I guess, for the Docking Module that's going up to repair the Hubble Telescope.
I can tell you two things;
1- They were built by Boeing.
2- No matter how much you like 'em, you can't afford 'em.
