To most people, the idea that the US, China and other countries are in possession of crashed alien spacecraft is preposterous. Any suggestion that these craft have been recovered with non-human intelligences inside, dead or alive, stretches credulity to breaking point. But the evidence is overwhelming.
I have been pursuing the truth about this phenomenon since I was a teenager, when I first saw a television report about a ‘flying saucer following a passenger plane’.
For five decades, I have conducted intensive research, combing through a vast body of material and interviewing many of the key people in this twilight area, some highly confidential sources.
I have applied the same rigorous analysis that I would as a lawyer to the evidence. I use in my new book Not For Disclosure only material that I have determined to be both honest and reliable, and which I can credibly and confidently present. I have discarded a great deal. I have also received very sensitive information from many whom I trust and who have placed their trust in me.
My concern about these extraordinary objects – once termed UFOs but now known as UAPs or Unidentified Anomalous Phenomena – has been shared by many influential figures.
When I was on the editorial board of the leading international journal, Flying Saucer Review, Buckingham Palace requested that a copy of every edition was delivered to the Duke of Edinburgh’s equerry. Prince Philip, of course, was a highly experienced pilot who quietly followed this subject, even having some witnesses interviewed at the Palace.
My professional life has been spent as a barrister, a King’s Counsel, evaluating evidence in very complex cases. I have done my best to bring that experience into this more anomalous arena, and my legal reputation has sometimes meant that I have been able to open doors that were closed to other researchers.
The shocking evidence that I have amassed proves beyond any doubt that not only are UAPs real, but they are undeniably evidence of alien technology. The sources of these non-human intelligences is still not known even by the intelligence services of the world.

The shocking evidence that I have amassed proves beyond any doubt that not only are UAPs real, but they are undeniably evidence of alien technology, writes Jonathan Caplan
More than that, the United States, China and Russia have been competing to reverse engineer and replicate these technologies, including anti-gravity, free energy and the real relationship between space and time.
I am fully aware how extraordinary this sounds. The principal motive for writing my book was to enable a wider and informed debate to take place without stigma or embarrassment. This subject is not on any educational syllabus and it is difficult to know where to access reliable material.
The ridicule surrounding the subject has not arisen by accident. A deliberate policy of denial and fabrication has been implemented by the US government and others, which has ended the reputations and even the lives of many people who have tried to lift the veil.
That is changing. In July 2023, a former Air Force intelligence officer named David Grusch went public under oath on live television before the US Congress, declaring that the United States was in possession of crashed NHI (non-human intelligence) craft.
Senator Marco Rubio, the US secretary of state and a probable contender to be the next president, told political website The Hill in July 2024: ‘Either what they are saying is partially true, or entirely true – or we have some really smart educated people with very high clearances and very important positions in our government who are crazy and are leading us on a wild goose chase.
‘What incentive would so many serious people have to make something up?’
Grusch did not say how many crashed NHI craft had been recovered, only that it was ‘in double digits’. One was seen by Lance Corporal Jonathan Weygandt. He was a US Marine posted to Peru in 1997, when he was sent with his unit one night to secure the site of a crashed aircraft, close to a radar tracking station.
‘We found the area real easy,’ he said, ‘because there was a huge gash in the land. It was like something had almost cut warm butter with a knife. It was a huge ship, buried in the side of a cliff. And when I first saw it I was scared.

‘It was dripping a syrup-like liquid – about 10 metres in width, 20 metres in length, like something between an egg and a teardrop.’
Whatever it was, this craft was not manmade. As far as Weygandt could work out, it had not crashed but was shot down, apparently by a Hawk surface-to-air missile. And something was still inside it, something alive.
‘I think,’ he said, ‘the creatures inside were trying to communicate with me telepathically.’
A US military unit in plain black fatigues arrived with a Nuclear Energy Support Team from the Department of Energy to recover the entities and the craft. Weygandt was arrested and taken by helicopter to a US Navy Medical Research Unit nearby.
Here, anonymous officers told him he was witness to something that he was not supposed to have seen. ‘I thought they were going to kill me. They threatened to take me up in a helicopter and kick me out into the jungle.’
His story might seem a hallucination, if it did not tally so closely with what we know about other crash retrieval operations. Unidentified craft are tracked in the United States through various agencies, including North American Aerospace Defense Command (NORAD), the National Reconnaissance Office, the National Security Agency and the Defense Intelligence Agency.
If a UAP is detected to have crashed, then special paramilitary units are sent to the scene together with the Office of Nuclear Energy in order to secure the area – just as Weygandt describes.
The CIA is also closely involved, and has recovered craft within US borders and from foreign territory both on land and under the sea. They have also engaged in operations to bring down craft.
When craft have been too large to recover, they have allegedly been left in place, buried under a building or structure while a facility is constructed underground to study it: This is said to have happened in the 1970s in the mountains outside Seoul, South Korea.
In January 1996, NORAD warned Brazilian authorities that a UAP was in their airspace. A cigar-shaped craft was seen by residents to be flying erratically and low before it crashed.
Multiple reports were made of strange beings with dark oily skin, large red eyes and three bony protuberances on their heads in the vicinity of the town of Varginha. Witnesses included three young women as well as military personnel and firefighters. A US plane arrived at the army base in Campinas to collect the wreckage and entities. Two of these creatures were captured. A military officer, Marco Chereze, who came into physical contact with one died soon after.
We do not know what happened to one of the beings but the other was taken to the regional hospital. The head of neurosurgery, Dr Italo Venturelli, attested last year that he went to consult with one of the beings for several minutes.
He said: ‘He was magnificent and very tranquil. I wondered if he was suffering but he was not. It was like he understood everything I was thinking entirely.’
Many suppose the history of crashed spacecraft begins with the 1947 Roswell incident in New Mexico, when a ranch foreman named Mac Brazel discovered wreckage scattered across a wide area. This included metal beams covered in hieroglyphic symbols.

At a second crash site, the main part of the craft was found with five small, non-human bodies inside. The official explanation was that the debris came from a ‘weather balloon’.
But a crash in Magenta in northern Italy pre-dates that by more than a decade. In 1933, a bell-shaped object was recovered from a site near Milan, though no bodies were found inside. A secret group known as Cabinet RS/33 was established to safeguard the craft and it reported directly to dictator Benito Mussolini.
Telegrams and notes from June 1933 have been discovered, ordering a Press blackout and establishing a detailed protocol for dealing with the object’s recovery.
At the end of the Second World War, the Office for Strategic Services (the OSS, which was the first US intelligence agency), with the assistance of the Vatican, arranged for the US government to take possession of the craft and to transport it back to an American facility.
Beyond any dispute, the international operations carried out across almost a century to keep this technology away from public sight amount to the world’s greatest ever cover-up. But the technology is only part of it. Even more disturbing is the non-human intelligence behind it.
Five alien species are commonly described in the literature but there are many more that have been reported. Paul Hellyer, the former defence minister of Canada, told me that he had been officially notified that more than 40 different species have been recorded visiting Earth.
The five main observed types include ‘greys’ which are most commonly depicted in popular culture, described as about 4 ft tall with large, teardrop-shaped heads, wraparound black eyes, no nose or ear protuberances and a straight line for the mouth.
The four other most commonly observed body types include small humanoids; larger, well-built reptilian-like beings; tall, fair Nordic types; and those with a mantid or insectoid appearance.
Dr Eric Davis, an astrophysicist who has worked for the US Department of Defense, confirmed his knowledge of these species at a Congressional event held by the House Committee on Oversight and Accountability on May 1, 2025.
Many researchers suspect the ‘greys’ are actually androids, arguing they are synthetic beings built to carry out tasks for the real NHIs.
There is a strong argument that today’s UAP encounters echo the content of our fairy tales and folklore, and even of some religious visions. Instead of coming across goblins and fairies, today it is aliens and spaceships.
Witnesses are often deeply affected by what they have seen, but prefer to say little, either for fear of being mocked or in many cases because they have been directly threatened. Sometimes though such events cannot be contained and become breaking news.
On July 1, 1965, a French lavender farmer named Maurice Masse, in Valensole in the French Basses Alpes, was smoking a cigarette just before starting his tractor for the day’s work when he heard a whistling noise. On the other side of his field, he saw an egg-shaped object resting on four legs.

Two small boys were squatting nearby in grey-green overalls, looking at the ground. They stood up when he approached. They were about 4 ft tall with bald heads and large slanted eyes. Their mouths had no lips and resembled a small hole.
He claims there was a telepathic exchange, then they pointed a ‘pencil’ at him causing temporary paralysis.
The craft took off at speed and, once he was free to move, he inspected the place where it had stood. The legs of the craft had left indentations in the ground. The local gendarmerie from Digne came to investigate and alerted government agents who concluded that Masse was not lying.
From then on the landing site, damaged and charred, would only grow weeds. Madame Masse told investigators that her husband thought about these beings every day and that it was a profound experience, something that should not be discussed with anyone. He shied away from media attention but his story quickly spread and was reported in the Washington Post four days later.
A UAP investigator named Jacques Vallee who interviewed Masse wrote: ‘The Valensole case is the best authenticated close encounter incident in continental Europe. It involved hard traces, botanical data, physiological data, and detailed descriptions of beings associated with the object.’
There are also claims of official contact, the most common being that arrangements were made for US president Dwight D Eisenhower to meet a group of extraterrestrials in 1954 at Edwards/Muroc Air Force Base in the Mojave Desert in California.
On another occasion president George HW Bush was informed, when he became director of the CIA, that a craft had landed at Holloman Air Force Base and a tall humanoid of Nordic appearance emerged and met with several uniformed and CIA officers. The Holloman contact was filmed but Bush was not allowed to view it.
The astronaut Gordon Cooper (who flew on the 1963 Mercury-Atlas 9 mission and 1965’s Gemini 5) was present on another occasion when a saucer allegedly landed at Edwards base in May 1957.
He and a crew had set up a Cinetheodolite precision-landing system on a dry lakebed – a system that could take pictures at the rate of 30 frames per second – for an exercise that had nothing to do with UAPs.
Later in the morning they saw a saucer hovering above them. It landed 160 ft away using three extended landing gears. As they approached to get a better view, the landing gears were retracted and the craft took off. Cooper, who was very familiar with experimental aircraft, had never seen technology like this.
When Cooper held the negative print up to the light, he observed that the quality of the photography was excellent. The film was speedily collected by an agent who arrived by special plane. Cooper never heard any more about the matter.
As Marco Rubio has said, why should a highly trained man like that, or his colleagues, lie about such an incident?
But perhaps the accounts that are hardest to dismiss are the mass sightings. On September 16, 1994, more than 60 children at a private elementary school in Ruwa, 12 miles outside Harare in Zimbabwe, were taking a mid-morning break while their teachers were in a staff meeting.
Suddenly, several silver spheres came out of the sky and seemed to vanish and reappear. The largest object came down, hovered and landed on a hill by some gum trees just outside their schoolyard.
The children, aged six to 12, saw one or two small men, about 3 ft tall, dark grey with long black hair, large black almond eyes and tight black suits, atop the craft.
Next day, the headmaster Colin Mackie asked them to draw what they had seen. He received 35 drawings, all very similar.
The BBC’s Zimbabwe correspondent, Tim Leach, was the first to arrive to film interviews. Leach later said: ‘I could handle war zones, but I could not handle this.’
He edited his report and sent the tape to London for BBC News but the tape went missing and he had to prepare a further one – but not before, he said, he had received veiled threats to ‘be very careful’ from a source whom he suspected was working with the CIA.
Several children said they had received telepathic information from the visitors. Lisel, 11, said: ‘I received through the being’s eyes the message that we are not taking care of the planet.’
That message could not be more benign. But the implications for humankind may not be. These craft are present in our skies and oceans in increasing numbers and no government today has any real idea of their agenda.
A race is underway between the superpowers to unlock their scientific secrets which may alter our worldview and our concepts of consciousness and reality.
China is known to have advanced UAP programmes with fewer restrictions on funding and better co-operation between scientists dealing with different projects.
In December 2012, former Russian president Dmitry Medvedev was recorded off-air telling a journalist that Vladimir Putin receives a regular report prepared by the special service ‘devoted to the strangers who visit our planet’.
This secret government agency concerns ‘the control of aliens in our country’. He said he could not talk about how many were among us because ‘panic will begin’.
He did not appear to be joking.
