I got to Repconn pretty early in this playthrough and my science was too low to check the targeting for the rocket Jason and the ghouls blast off in. Where does it end up?

Three rockets, isn't it? I'm thinking space station or smoking crater. Maybe I missed something, though -- is their destination revealed?

I don't think the destination is ever revealed, but here are some endings that imply...

Well, if you believe No-Bark, they're going to the moon. However, he says they're communist ghosts that want to paint a Lenin face on the moon.

They obviously flew to Tamriel. :laugh:

A smoking radioactive hole in the Capital Wasteland?

They made it to low orbit, then were vaporized by Aliens.
