The evening of September 19, 1961, the Hills were driving back to Portsmouth, New Hampshire. South of Groveton, they are said to have observed a bright point of light in the sky. Approximately one mile south of Indian Head, the craft rapidly descended toward the Hills' vehicle causing Barney to stop directly in the middle of the highway. Opening the car door for a closer look, Barney pocketed his pistol and grabbed his binoculars. The craft descended to approximately 80-100 feet above the Hills' 1957 Chevrolet.
Betty described the aliens as small men who stood about five feet tall, and wore matching uniforms, with caps similar to those worn in the U.S. Air Force. They had no hair on their heads, and had large bulbous foreheads.
Betty, Barney and the small men all walked up a ramp into a disc-shaped craft of metallic appearance. Once inside, Barney and Betty were separated. She protested, and was told by a man she called "the leader" that if she and Barney were examined together, it would take much longer to conduct the exams. She and Barney were then taken to separate rooms. Though the leader and the other men spoke to her in English, their command of the language seemed imperfect, and they had difficulty communicating.
Betty then proclaimed that a new man, similar to the others, entered to conduct her exam with the leader. Betty called this new man "the examiner" and said he had a pleasant, calm manner. The examiner told Betty that he would conduct a quick exam and a few tests to note the differences between humans and the craft's inhabitants. He seated her on a chair, and a bright light was shone on her. The man cut off a lock of Betty's hair. He examined her eyes, ears, mouth, teeth, throat and hands. He saved trimmings from her fingernails. After examining her legs and feet, the man then used a dull knife, similar to a letter opener to scrape some of her skin on to a glass slide.
The doctor removed Betty's dress. He told her to lie on a table. Saying he was examining her nervous system, he dragged a machine somewhat resembling an EEG device over her front and back body.The doctor cleaned his hands with a liquid and put examination gloves on. He took out a hypodermic needle some four to six inches long to conduct what he said was a pregnancy exam. He used a wet swab on her navel. He thrust the needle into it, which caused Betty agonizing pain, but the doctor rubbed her forehead and the pain vanished.

So out here on this lonely road, on the top of a small hill, is a decontamination kit in case you get abducted.
