Interesting. But the programs in this paper are all written in FORTRAN and need to be run on large(ish) computers. Airplane design went straight from sliderule to mainframe and mostly bypassed the pocket calculator... When I started to study aerospace engineering two years after this paper was published, one of our early tasks was to do the FORTRAN course.

You missed the HP-25 program in section 8. It's an odd program, step 01 is [R/S], but I didn't read the full section to understand operation; maybe there's a reason for that.
