You're Not Going to Believe This, But...
I read the book on this, "Witnessed: the True Story of the Brooklyn Bridge UFO Abductions" and assuming everything he wrote in there is true, it is an amazing and well-documented story. The guy who wrote the column above dissecting the case says he's seen the documents. If the documents are real, then it's hard to see how this story was a hoax.
The Cortile case, later published as Hopkins' book Witnessed: the True Story of the Brooklyn Bridge UFO Abductions, focused on a Manhattan housewife allegedly drawn out of her 12th story window in Lower Manhattan and lifted up into a UFO that turned on all its lights at 3:00 am, November 30, 1989. Although the details of the story were convoluted, involving alleged alien abduction, government cover-up, kidnapping and attempted murder by secret agents, and more, Hopkins believed the case supported "both the objective reality of UFO abductions and the accuracy of regressive hypnosis."
Hopkins died in 2011. A video of Cortile can be seen on Youtube here, in a video by Hopkins' wife, who apparently is skeptical about the abduction research.
Here's a whole website devoted to defending the Cortile case, and has a rebuttal to Hopkin's wife and lots of other stuff.
