Dear Jack, As regards your question, "Is there any way of finding out how much money was spent by NASA on V-R?", I would imagine that the US Audit Office must have a figure, though whether that is available to the (non-American) public, I don't know. Marshall Hall ( www.fixedearth.com ) has several pieces about this on his website (and in the September bulletin, I believe). Regards, Neville.
