How to Start Building A Spaceship

[GhostOfDisco]

Recenlty I did some work on Sobieski - having figured out a way (I think) to incorporate the "Apollo" aspect of Civ II (it's about royal elections), I'd thought I'd test it out by building the Apollo wonder and building a "ship." I build the wonder, and I've got all the techs I need to build space parts (as of the testing part, the Apollo and ship parts' required techs were set to "nil"), but none of them appear in the production menu! So, what else do I need to do to begin spaceship construction?

I'm not sure, but try adding whatever tech went in the rocketry slot. It may well be like the Manhattan Project, where you need an additional tech (in that case, Nuclear Fission).
