Born at an early age of mixed parents, a man and woman (this must be made clear nowadays), my early childhood was a disaster. My imaginary playmate would have nothing to do with me, though I thought he was the greatest.Since then it's been all downhill. Seriously, I'm a former aerospace engineer (Lockheed Missiles & Space Co., later with a developer/vendor of Flight Motion Simulators, and later still as technical journalist for a developer/vendor of GPS Systems). Some time ago, I took up writing science fiction as an avocation. First published during the dark ages (1970s hardcover sf novels by then-Doubleday & Co., and St. Martin's Press, plus magazine shorts, novelettes, a co-authored serial novel, and a science article). Currently, nine of my self-published novels (eight "hard" speculative fiction, the ninth a humorous spoof on the U.S. aerospace industry), are available as softcover books, as well as ebooks, and a tenth title only as a e-book.
