...but don't you think, Tom, that Boeing or Lockheed
already have detailed 'blueprints' and CAD-CAM designs
for a 3-4 man (Apollo-type) space-capsule
stored away somewhere?

All that is needed for a basic fullscale "mock-up" to be
build on short notice is...the word from O'Keefe, and
Boeing's CEO saying, "let's start cutting metal!
Get them jigs and templettes ready for the machine-tools!"
(I'm assuming they still use jigs and templettes with
manufacturing machine-tools)

Look! It took only a little more than SEVEN YEARS from Kennedy's
announcement in May/1961 until the Apollo-8 CSM circled the moon.

Seven years from today is 2011; a few months after the last shuttle
would be retired.
