1) The cost
It costs much less to fake a space program than to actually have one.
Cost of McMurdo Base per year $197M (1997 price)
Estimate 72 similar bases (500 kms apart for 36,600 kms - estimate of perimeter)
Annual cost (72 x 197) = circa $14 Billion per year.
Total cost of the space shuttle program -> $145 billion over 23 years
Annual cost $6 Billion per year
2) There is no motive
Money can be a surprisingly good motivator.
This is true, but what possible money could be made by pretending the earth is round when it is flat?
3) There is no evidence
There is actually quite a bit of evidence.
Please present one example, preferably independantly confirmable.
4) It is such a big undertaking, it could not be kept secret
Only a few people have to know about it. The rest of the NASA employees only know what they see on a TV screen.
Sorry to be crass, but President Clinton could'nt keep 1 BJ secret, and only 2 people knew about that.
The onsite staff at the bases would be at least 1000.
Life "In the Freezer" over winter causes many psychological problems, you get an extreme version of cabin fever (apparently everyone gets it sooner or later) because of this, there is a very high turnover of staff.
Every country in the world with a space program (there are at least 30) would have to be complicite with the conspiracy
This includes Russia and the USA during the cold war. The is entirely unlikely.
5) Machine guns don't work at -20 Centigrade (joke BTW)
I don't see how this is relevant.
It was a joke

- it was in part a parody of the flippant nature with which (what I have read about) this conspiracy seems flung together.
Not one point has been seriously contested.
I've contested quite a few of your points.
Thanks

My last one got moved to "Angry Rants" - there was nothing angry about it.
I'm not sure who moved it there but it was moved back.
Thank you very much.
I appreciate it
