I think once we made the Guiness Run, Outer Space was a done deal.
That's why we went to the Pacific, I think...somewhere to get some U-know-what to go U-know-where. ;o]
I think it was discussed while we were in Loch Ness. It had to have been before we left there, because we stopped in the Norwegian Sea to pick up the Thrust Ring, (necessary for space travel.)
That was also where we discovered we needed to beef up our hull integrity, because we had "an intruder."
