Nope. I'm thinking of the 2nd 5yr mission that never was a 5yr mission. Any book that mentions a 2nd 5yr mission has it wrong.
Why couldn't there be another 5 year mission?
1.) It's fiction. It's ALL made up.
2.) There's supposed to be a 10 year gap between TMP and TWOK. Fill in the gap.
3.) Make it up. If you want to believe there was another 5 year mission, then by all means, believe there was another 5 year mission. Unless some other book contradicts that, who's to say you're wrong.
4.) Other than JWolf.
5.) 5 year missions rock!
