Questions on Enabling Techs??

[The_Aussie_Lurker]

Hi Guys,
I don't know if anyone out there can help me, but I'm trying to get a handle on a few Advance related issues.
#1) In the Avault Strategy guide, it's said that the U.N becomes available after nuclear fission. Yet I can't see anything that matches this wonder ounder that section of the tech tree. Additionally, they say that tac-nukes become available with space flight, and ICBM's with sattelites. Is this true? If it is it seems quite strange. I suspect an error considering that, according to the guide, you don't get nuclear subs until you have Fusion!!!

#2) When you get flight, I can see 3 things which become available. The first 2 are the bomber and the fighter, but the 3rd looks like a tower of some sort, possibly a tile improvement? What is that. I can't get a close enough look to see it, but I thought maybe someone else might!!

Anyway, any clarification would be most appreciated.

Yours,

1)Yes, the UN wonder is visible under Fission, and the "fusion" thing is a typo, you do get nuclear subs with fission.

2)Probably an airport city improvement.

Yes, that's my guess. It might be an picture of a Control Tower of some sort.

Strange, under fission I see 2 things. 1) A picture of an, obviously, nuclear submarine and 2) The Fat Man atomic bomb (which obviously relates to "The Manhattan Project"), but no U.N picture?! Could you possibly send an attachment of it so I can see?

Secondly, the airport improvement can be clearly seen under radio. So the flight related improvement "might" be a Radar tower (increasing the visibility of a city or, if it's a tile improvement, then allowing you to detect enemy units passing that tile??)

On another note, what's the "Castle" I can see under the Monarchy Advance?

OK Guys, having looked at a more enlarged Tech-Tree on the Civ Fanatics Site I think I've managed to work out the following:
1) Radio enables the U.N (I think, though it kind of makes sense!)
2) Flight enables Airport (again, makes sense)
3) Space flight has pictures of TWO missiles, making me think that both tactical nukes and ICBM's become available at that time! (This isn't so bad, as you probably will have just finished The Manhattan Project" by the time this advance is researched!!)
4) Communism enables Police Station (as before, though what it's effect might be is uncertain!)
Anyway, if anyone has a better interpretation of the modern/industrial tech tree than this, then I'll be glad to hear it, and thanks to those who've tried to answer my questions.
