That reminds me, I dunno what's going on, but I have three Jebs from regular gameplay alone. I work carefully to keep them from encountering one another. If they did, who knows what might happen.
I absolutely love how much this thread derailed. I have never done a successful orbit (last one ended in landing on the dark side of the planet, which is apparently made of antimatter or reverse-explodium) but I once did one of the ridiculous straight-up flights and then managed to land on the launch tower. It was pure luck though.
