To give you a little background information, I am the Trustee of Betty's archival collection and have photocopies of her files that fill two four drawer file cabinets in my home office. The fact that I specialize in the Hill abduction case and have so much material on hand makes it possible for me to fact check quite easily. Whenever I encounter a statement that appears to be inconsistent with Betty's documented information, I attempt to set the record straight.
I do this without malice. Certainly memory is malleable, and although we might retain the whole picture of an event that occurred several years ago, specific details might be mis-remembered or altered somewhat. I suspect that this is what happened to Gordon. I am not attempting to criticize him--only to correct a small mistake and to offer what I suspect might be a more accurate account of the memory he retrieved.
Anyone who has a copy of Betty's 1995 book, A Common Sense Approach to UFOs, will find documentation that supports my statement that Betty did not believe that she is the only person ever to have been abducted. Refer to Chapter 6 on page 81, "Criteria for Real Abductions" and Chapter 7 "Reality." She states on page 85, "Real abductions do exist but they are extremely rare." Betty discusses the differences between what, in her opinion, are real vs psychological abductions in Chapter 6. She discusses the experiences of a man who she thought had a real abduction. "The day after the abduction, he was too ill to get out of bed. The third day he went to the doctor who did some tests on him." She then discusses the abduction of a couple who lived hundreds of miles apart but were abducted from a vehicle when they were riding together. Chapter 7 gives brief case histories of several additional abductions that met Betty's criteria as being veridical experiences.
