good point, but do the Russians have another Progress (which I am sure NASA is paying for at this point) ready?

Good question, actually. Yeah, you do have a point, I was just "assuming" they had another one in stock and/or ready. I know it is dangerous to assume but I think it would be wise to have a second and third ready to go for "just in case."
