G. Harry Stine  was an engineer, an SF author (under the pen-name Lee Correy), and for about thirty-five years, off and on, author of a science fact column for Astounding/Analog. He was a big space booster. His 1975 book, The Third Industrial Revolution was a best-selling popularization that predicted a great age of space exploitation that would begin in the 1980s.
Of course Stine was also a True Believer in the Dean Drive. Maybe fourteen-year-old James should have taken warning from that. In fourteen-year-old James’ defense, he was somewhat credulous when it came to SPACE!
