The Shuttle is great - but it doesn't compare
to the power of a Saturn V.  The launch
was an experience not to be forgotten.

Spoken as an Apollo-era youth who saw the launch
of Apollo 14 from inside five miles.

Check out some of the historical stuff at
the NASA history pages at:

Can't wait to see what the dreamers (engineers)
think up next to go beyond the Shuttle.
