I am looking for a copy of the paper "An Interstellar Precursor Mission" by L.D. Jaffe. It was published as a JPL report (JPL-PUB-77-70) and in the JBIS (vol. 33, Jan. 1980, p. 3-26). Does anybody have a copy and can send me a scan?
I have looked on NTRS but the paper is not available in pdf format
