In the How to Achieve Cats (Cheap Access to Space) there were three Popular Mechanics links included at the time I wrote and posted the page to the old CommonSenseCentral.com...THAT domain was, and remains, STOLEN, from me as the ORIGINAL registrar of that name, In setting up CommonSenseCentral.NET I had to review the entire site for 'dead links' and those three Popular Mechanics Articles were no longer available on the web, nor at the Popular Mechanics Site itself in it's archives. I decided to have a librarian help me find them again.
The following was retrieved from Plattsburgh NY Public Library October 31, 2007 since original links were now dead in 2007.
The following are color scans from printouts from their database.
End of rebuild of link.
