Ive got my google earth set up with the neat thing where it can read
an .igc file and then I can view the flight on my computer.

Im working on a class project on space shuttle reentry. *our FORTRAN
code will find an acceptable reentry path for the shuttle so it doesnt
burn or break up, and flies a nice pattern to landing and Kennedy
Space Center. *we will be figuring out lat/long and altitudes during
the entire trip down. *What format do I need to use to write out this
data so that I can load it onto Google Earth for a sweet
visualization??

Check this site. http://www.gpsvisualizer.com/gpsbabel/gpsbabel_convert
Converts many GPS file formats to many OTHER GPS file formats.
My personal preference would be the .igc format, then it could be
'played' on Google Earth using the IGC Playback utility, which was a
subject here a while back. Also 'playable' with See You and many
others.
