I complete every single part of my spaceship and launch in 1952. The screen says "10 turns to victory!" Joao lauches his spaceship in 1953. Nine turns later, the screen says 1 turn to victory!" I press enter to end the turn... ...the screen says, "Joao II has won a spaceship victory!" How did Joao get there in eight years? Does AI have quicker spaceships? Is it possible to skip some parts and have a faster ship?
