    Hello all. Does anyone have a copy of Jim Barrowman's original pamphlet for >> NASA? It was published by the Educational Services Office, and was in the
    "Information For You" series. The title is "Calculating the Center of
    Pressure of a Rocket". This was put out in the mid 60's.

    Here's the thing, finally released by NASA :

    THE PRACTICAL CALCULATION OF THE AERODYNAMIC CHARACTERISTICS OF SLENDER FINNED VEHICLES, by
    James. S. Barrowman https://ntrs.nasa.gov/api/citations/20010047838/downloads/20010047838.pdf?attachment=true

    Very nice. I used this to write a 4 card HP-65 series of programs for
    model rocket design. Modern computers are of course much faster. But I enjoyed the vintage machine.
