Good idea. But don't the SSMEs go into orbit? Does their pod need both retro-rockets and an ablative heat shield to re-enter safely before deploying the chutes? Also, aren't the complex liquid engines more easily damaged by the splashdown and salt water corrosion while they're waiting to be fished out of the water? BTW, do the Russians use ablative shields on their Mir re-entries, or has something better been developed?
