How were these costs incurred? I have a detailed document describing the 
first United States manned orbital space flight  and that was done using 
ft, inches, Lbs, degrees F etc, but that was in 1962. I find it hard to 
believe the use the same units these days.
Modern USA scientific literature seems to be metric.
