I have, for the 07:09:11 UTC, 02 Dec Mars Pathfinder launch, the
following based on data kindly furnished by David Spencer (JPL):

Shadow entry is at 08:15:47 UTC, exit at 08:45:37 UTC. See 
http://mpfwww.jpl.nasa.gov for more background and look at
http://mpfwww.jpl.nasa.gov/mpf/launch_profile.html for a summary of the
launch profile.

David's state vectors are as follows (in case Bjorn wants to try out his
new toy):
