The Day the Earth Died

"The Day the Earth Died" from Rip Hunter... Time Master #15 (DC, 1963) by Jack Miller and Bill Ely

Oh well... Let's hope it's sometime in the future. You know, I love time travel stories, but every Silver Age Rip Hunter story has been filled with aliens and weird goings-on, or else things like famous beauties from history competing in pageants. Should I be complaining? I guess it's a lot like what Doctor Who has become...
