I found the information

Thanks for the clue. The information I was looking for was at NIAC.
For those of you who are interested, the specific reference is

http://www.niac.usra.edu/files/studies/final_report/pdf/23Seward.pdf

I knew that someone on this list would be able to point me in the
right direction.

Thanks to all of you. Without your help I would have been searching
endlessly.
