     If you watch one of the 5-minute-long NASA animations of the
landing sequence on YouTube (search for "Seven Minutes of Terror"), a
screen goes by with the text "500,000 L1NES OF COD3".  I initially
though COD3 was some sort of special purpose language that NASA created
to fit the requirements of spaceflight.  Then I noticed the '1' in L1NES
and now I suspect that they were probably just being cutsy with the
text.  Does anyone know?
