After the most recent example of launch delays I wish to add a simple consideration to my opinion about the "one-and-half" launch architecture.

It's too easy to talk of the Shuttle as an "example of launch delays" (one year of delays from last launch and we are not sure that it will really fly in july...) but the delayed launch of the CloudSat and Calipso is a clear evidence of the problem: a very long delay due to a strike by Boeing workers and now SIX delays in a week due to technical and weather problems!

And this was a very simple launch of two simple (and unmanned...) satellites with a little, simple and reliable rocket!

Just imagine what may happen with two, big, new (then, experimental), very complex and (one) manned launches like the CEV/SM/CLV and the LSAM/EDS/CaLV!

The delays of to-day's satellites and Shuttles launches may be multiplied by TEN!

I've read hundreds of posts in dozens of threads/forums (and articles on newspapers and websites) but near ALL users/journalists prefer to ignore the problem.

They all (but also NASA and press) talk about the CEV dimensions, the SSME/J2X CLV 2nd stage dispute, the 4/5-segment 1st stage change, etc. etc. etc. but NEVER of that problem.

That is VERY INCREDIBLE for me because it's like talk about the dimensions, materials, use, elevators, floors, color, windows, price, parking, air conditioned, furnitures, lighting, streets, doors, etc. etc. etc. of a giant and very very expensive 2000 feet new skyscraper with all (engineers, buyers, etc.) ignoring that it is built on a sand-like terrain and may collapse after its inauguration!!!

I think that, BEFORE start making the building NASA must give it a solid ground with a reliable "single launch architecture".

Ignore the problem is not a good and savvy policy!
