A 70-year-old man, Maishe Rosstein, undergoes open-heart surgery. Details of his procedure open the novel/novella. Once in recovery in ICU, in Intermediate, later at home, he recalls that during the procedure, he perceived through a glass darkly his days entering the Air Force (AF), his duties, the women he meets, and other events. More than mere dreamy recall, it is as if he lives them again. Thence, the story returns where it began, at his home, recovering, now with new insights about his life.
Please note that once USAF classified information is included, albeit now declassified and available to the public.
