There is a discussion among UFO enthusiasts as to whether or not the objects being reported are actually material in nature. Cases where there have been physical traces left behind after a sighting support the argument that some objects are indeed solid but there were times when those traces were left behind none-too-gently. Actual collisions have been reported between UFOs and aircraft, cars and, possibly, even a train according to a report referenced to in the forum section of Trains magazine.
The most famous case involving a UFO hitting a car comes from Marshall County, Minnesota. At around 1:40 AM on August 27, 1979, Deputy Sheriff Val Johnson was driving on duty close to the North Dakota Border when he saw a light. He described it in a taped statement for UFO investigator, Guy Wescott, as “a very bright, brilliant light, eight to twelve inches in diameter, three to four feet off the ground” with well-defined edges. Thinking it was a landing light from a distressed aircraft, Johnson drove towards it, traveling a little over a mile, when it suddenly came towards him and “intercepted” the vehicle. Johnson lost consciousness for “approximately thirty-nine minutes” and came to with his car stopped sideways across the road at the end of 99 feet of skid marks, and a total of 953 feet from the site of impact. He radioed for help and Deputy Sheriff Everett Doolittle was the first to arrive. Doolittle found Johnson sitting in the driver’s seat, in a state of mild shock, with his head against the steering wheel. Johnson complained of pain in his eyes that reminded him of burns he’d experienced after welding and said his head felt as if he’d been hit “in the face with a four-hundred pound pillow.” Doolittle called for an ambulance and Johnson was taken to a hospital where his eyes were treated with salve and bandaged.

It often occurs among UFO enthusiasts that people will form a belief in a case and find it difficult to let go of that belief in spite of evidence that the case was more than likely a hoax. The alleged 1948 crash and retrieval of a flying disk near Aztec, New Mexico is a classic example. This case has spawned the well-known 1950 book by Frank Scully,

The April 24, 1964 sighting of a landed UFO with two beings standing next to it by Socorro, NM Police Sergeant, Lonnie Zamora has been written about extensively and remains a fascinating mystery to this day. What’s particularly interesting about this case is how many people investigated it. Representatives from the Socorro Police, New Mexico State Police the F.B.I. and Army were first on the scene followed by the Lorenzens from the Aerial Phenomena Research Organization, members of the Air Force and J. Allen Hynek as part of Project Blue Book, and Ray Stanford for the National Investigations Committee on Aerial Phenomena. Besides the testimony of Zamora, there was trace evidence to examine, witnesses to a similar craft to interview, and reputed witnesses to the very craft Zamora reported who were searched for but never found. Despite the thoroughness of the inquiries and analyses by so many experienced investigators, no one was able to come up with an agreeable Earthly explanation.
According to Zamora’s written 
APRO was formed in the fall of 1951 through the efforts of Coral Lorenzen with the help and encouragement of her husband, Jim. Coral’s interest in UFOs preceded the 1947 Kenneth Arnold sighting by more than a decade following her own sighting of an unexplained object. Coral claimed that in 1934, as a young girl with the maiden name, Lightner, she and her two playmates, Barbara Stringer and Dorothy Wethern, saw what looked like a parachute moving across the sky. Coral noticed that it didn’t have any strings and this caused her to question whether what she was seeing actually was a parachute. She told her father what she had seen and he was impressed enough to make inquiries and found that there were no pilots in the area at that time. Three years later, at the age of 12, Coral was being checked for astigmatism and told her doctor what she had seen. He recommended that she read the books of Charles Fort, a writer who was a pioneer chronicler of the strange and unusual, and Coral developed an interest that would stick with her for the rest of her life.
In 1951, Coral and Jim Lorenzen were living in Sturgeon Bay, Wisconsin after a brief stay in Los Angeles. While in Los Angeles, they had met contactee, George Adamski, and Coral reported that she was unimpressed by his claims, in part due to his repeated references to the moon as a planet. In Wisconsin, Coral decided to start a group that would keep track of sightings reports and she wrote to people she knew who might be interested. Around fifty responded positively and the Aerial Phenomena Research Organization came to be. Coral had chosen the name, consciously avoiding the term, “flying saucers” which she found distasteful. The center of operation for APRO was an antique table with clawed feet in the corner of the Lorenzen’s living room and the means of communication among its members was a portable typewriter.
