Well, I'm a... less recent grad and in all of the time that I worked as an AE, almost all of it was with Fortran. All of our CFD codes are in Fortran. All of the legacy aerodynamic performance codes are in Fortran. This also seems to be the case with our partners in the Air Force and with other corporations.
Perhaps it's different in your sub-discipline?
I don't think the person writing the summary was implying that the list was DoD classified. I read this as being a more generic definition of "secret". Plus, it's pretty obvious from reading the document that it is not "SECRET".
I can't speak for anyone else, but I'm pretty religious and I actually like my life. I enjoy spending time with my family and I'd like to hang around for a while. I actually don't spend a great deal of time thinking about the afterlife. I find that living my beliefs makes me happier in this life.
