What's the "lower receiver" of a rocket stage?It's the structural airframe, which is the combination of the thrust structure and fuel tanks. For all practical purposes, those are not replaceable, and if the airframe is worn or damaged to the point where it cannot be repaired the booster is toast.

It was the Thaicom 8 first stage that's being converted to a FH side booster, and apparently the octaweb is being ripped apart as part of this conversion process. Will we count that as reflight of a stage?
