[Proj] Need info on Pittman's paper on geodesics

[Charles Karney]

I'm looking for Pittman's paper on geodesics:

    M. E. Pittman.
    Precision direct and inverse solutions of the
    geodesic, Surveying and Mapping 46, 47-54 (1986)

Does anyone know how to get hold of this paper?  (Paying is OK, up to a
point.)

Also, does anyone know Pittman's method in enough detain to describe it?

Thanks!
